MPLCTecVirtualEncoder Introduction I 2 2 MPLCTecVirtualEncoder 2.1 Introduction The MPLCTecVirtualEncoder library offers function modules for implementing a virtual motor axis. The motor axis can be operated like a real drive in various operating modes. You can operate the virtual encoder as speed-controlled motor axis move to absolute target positions in positioning mode perform endless movement over a specified distance Velocities and ramps can be set, which means a specified travel profile can be implemented. Depending on which mode is set, the current position of the virtual encoder is sent via the SBus with a resolution of 496 increments (MOVIDRIVE B mode), or with 65536 increments per revolution (MOVIAXIS mode) as cyclic transmit object. It can be used as master value, for example for synchronous operation slaves or electronic cam slaves. 2.2 Areas of application The MPLCTecVirtualEncoder library is suited for all applications in which a central position master value is needed. This position master value is then used as common master signal for several motor axes in a synchronous operation system. Application examples Material handling, e.g. two-axis pick and place unit Synchronous material transportation, e.g. several conveyor belts are synchronized to one master Multi-axis hoists/trolleys Packaging technology, e.g. tubular bag machines Properties Two independent virtual encoders are possible Various operating modes: Absolute positioning Relative positioning Speed control Absolute modulo positioning Relative modulo positioning Setting the current position to a certain value ("virtual reference travel") Current position can be stored in a non-volatile memory ("Absolute encoder functionalilty") Adjustable cycle time for sending the position Automatic setup of a synchronization object for synchronizing the SBus MOVIDRIVE or MOVIAXIS mode selectable with corresponding scaling of velocities and ramps as well as respective encoder resolution Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC 7
I MPLCTecVirtualEncoder 2 Project planning 2.3 Project planning 2.3.1 Prerequisites To be able to use the MPLCTecVirtualEncoder library, you need a MOVI-PLC controller in technology version T1 or higher. 2.3.2 Basic principle and notes The MPLCTecVirtualEncoder library automatically includes the MPLCTecFct_ProfGen library. The LinProfGen function module represents the actual profile generator. This function module is configured to the required function by the library modules in order to keep handling the virtual encoder as simple as possible. The MC_LinkTecAxis_Virtual function module is mandatory for using the virtual encoder. The function module is used, among others, to determine the logical address and the synchronization object for SBus synchronization as well as to create the send object for the current position. This function module must be called in a cyclic task that corresponds to the set cycle time (recommended: 5 ms function module is called cyclically at intervals of 5 ms; so-called 5 ms task) The sycnchronization object has the fixed identifier 1 (ID1). The send object of the first virtual encoder is assigned ID 2 and the second virtual encoder is assigned ID3 to ensure that these objects have the highest priority on the SBus. The current position of the virtual encoder is stored in a non-volatile memory. Some of the system variables are used for this purpose. System variables beginning from H2 should therefore not be written by the user program. 2.3.3 Project planning procedure The function modules of the MPLCTecVirtualEncoder library are divided into three directories.

VirtualEncoder_ SingleAxis VirtualEncoder_SingleAxis directory: MC_MoveAbsolute_Virtual function module The MC_MoveAbsolute_Virtual function module lets you start a positioning travel to an absolute target with specified velocity and ramp. MC_MoveAbsoluteModulo_Virtual function module The MC_MoveAbsoluteModulo_Virtual function module starts a positioning travel to an absolute target in modulo format with specified velocity and ramp. MC_MoveRelative_Virtual function module The MC_MoveRelative_Virtual function module starts a relative positioning travel from the current position with specified step width, velocity and ramp. MC_MoveRelativeModulo_Virtual function module The MC_MoveRelativeModulo_Virtual function module starts a relative modulo positioning from the current position with specified step width, velocity and ramp. MC_MoveVelocity_Virtual function module The MC_MoveVelocity_Virtual function module starts a process of endless movement with set velocity and ramp (speed control). MC_SetActPos_Virtual function module The MC_SetActPos_Virtual function module is used to set the current position to a specified value. In this way, a virtual reference travel can be implemented comparable with reference travel type 5 for MOVIDRIVE. MC_Stop_Virtual function module The MC_Stop_Virtual function module stops an already started travel of the virtual encoder. 1 Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC
MPLCTecVirtualEncoder Overview of the MPLCTecVirtualEncoder library I 2 2.4.1 Determining the address and addressing of the virtual encoder The MC_LInkTecAxis_Virtual function module determines the axis reference AXIS_REF_VIRTUAL from the input SendObjectID as logical address for the remaining modules of the MPLCTecVirtualEncoder library. The MPLCDatatypes library includes the file type MC_PDO_ID_MDX where two settings are provided for the virtual encoder ( following figure). 61653AXX Example The MC_LinkTecAxis_Virtual function module contains the "MDX_VIRTUAL_ENCODER_ID1" signal at the input MDX_VIRTUAL_ENCODER_ID1 and outputs the axis reference LogAdrVirt as logical address at the output VirtualAxis ( following figure).

These status messages are saved and deleted by the relevant Move function modules because the profile generator in the MC_LinkTecAxis_Virtual function module is edge controlled. This is the reason why the status messages of the Move module should rather be used for inhibit or step enabling conditions in the user program. 12 Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC

I MPLCTecVirtualEncoder 2 Overview of the MPLCTecVirtualEncoder library 2.4.4 Function modules of the MPLCTecVirtualEncoder library MC_LinkTecAxis_Virtual function module MC_LINKTECAXIS_VIRTUAL Enable : BOOL CycleTime : BYTE Modulo : BOOL SaveActPosition : BOOL SendObjectID : MC_PDO_ID_MDX Node : CAN_NODE Done : BOOL Busy : BOOL Error : BOOL ErrorID : DWORD VirtualAxis : AXIS_REF_VIRTUAL VirtualAxisData : MC_DATA_VIRTUAL LinkState : MC_LINKTECSTATE 61656AXX Description The MC_LinkTecAxis_Virtual function module constitutes the logical interface to the technology function "Virtual encoder". The axis reference is determined using the SendObjectID input signal and the logical address is output as VirtualAxis output signal. The send objects for the cyclical sending of position and SyncID are created during the initialization. You can set the cycle time of the virtual encoder using the input signal CycleTime. If the input Modulo = TRUE, the modulo position will be sent, else the linear position will be sent. These settings only refer to the position to be sent, not to the modulo function as such. This means positioning can be performed in modulo format but the linear position will be sent. The input signal SaveActPosition lets you set whether the virtual encoder will start with the last actual value when the power supply is switched on, or whether it will start at position "". The current position, velocity and current status of the virtual encoder are available as output values. NOTES The MC_LinkTecAxis_Virtual function module is mandatory for using the virtual encoder and must be called cyclically in the program. If the output signal LinkState has the status NOTLINKED, none of the function modules of the MPLCTecVirtualEncoder library can be executed. The relevant error message will be issued. Note that the MC_LinkTecAxis_Virtual function module is called with the same cycle time as set at the CycleTime input. The virtual encoder can basically operate with a cycle time of 1 ms. The cycle time might be violated because internal system functions are also being processed during this time. SEW-EURODRIVE therefore recommends to set the cycle time to 5 ms or 1 ms. Different SendObjectID must be assigned for several virtual encoders even if they are created on various SBus nodes. 14 Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC

MPLCTecGearMotion_MDX Introduction I 3 3 MPLCTecGearMotion_MDX 3.1 Introduction The MPLCTecGearMotion_MDX library is based on the technology function "Internal synchronous operation (ISYNC)" of the MOVIDRIVE drive inverter. The following simplifications have been achieved compared to the previous solutions. Before: Familiarization in the SEW-specific programming language Specific knowledge required for creating and setting the parameters of the system variables for synchronous operation Solution with MOVI-PLC : Programming in accordance with IEC 61131, which means customer-specific applications can be easily implemented. Library for controlling the technology function "Internal synchronous operation". In this way, the technology function "Internal synchronous operation" can be configured and controlled easily without detailed knowledge of the individual firmware functions. Up to 12 (with MOVI-PLC basic) or up to 64 (with MOVI-PLC advanced) synchronous operation motor axes can be controlled centrally. Additional functions, such as specifying master values via a virtual encoder, are controlled centrally using the MOVI-PLC controller NOTES For general notes on the theory of operation of the library, refer to the "MPLCMotion_MDX and MPLCMotion_MX Libraries for MOVI-PLC " "MOVIDRIVE MDX61B Internal Synchronous Operation (ISYNC)" manual. 3.2 Application areas The MPLCTecGearMotion_MDX library is suited for all applications that require synchronized axis movements. Application examples Flying saw, e.g. to cut endless material Synchronous material transportation, e.g. several conveyor belts are synchronized to one master Multi-axis hoists/trolleys Filling station in the beverage industry Packaging technology, e.g. tubular bag machines Properties Up to 12 (with MOVI-PLC basic) or up to 64 (with MOVI-PLC advanced) motor axes can be operated in synchronous operation A variety of configuration options can be set clearly structured with the relevant function modules Various master encoder sources can be set Lag distance can be saved protected against power outage (for a limited time) Various master/slave combinations can be implemented; several synchronous operation masters can be configured Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC 35
I MPLCTecGearMotion_MDX 3 Project planning 3.3 Project planning 3.3.1 Prerequisites In order to use the MPLCTecGearMotion library, you need a MOVI-PLC controller in technology version T1 or higher. A MOVIDRIVE B unit in standard version (..) is sufficient as drive inverter. Information in the "MOVIDRIVE MDX61B Internal Synchronous Operation (ISYNC)" manual The MPLCMotion_MDX library must be integrated. The prerequisites mentioned in the "MPLCMotion_MDX and MPLCMotion_MX Libraries for MOVI-PLC " manual apply as well. 3.3.2 Basic principle and notes Existing scope of functions of the ISYNC technology function are used with MOVIDRIVE B. Setting the corresponding system variables for synchronous operation using IEC function modules. Automatic changeover of ramp types during direct startup cycle or while preparing the startup cycle. On-the-fly changeover from synchronous operation to positioning. The MPLCTecGearMotion_MDX library should cover the most frequent synchronous operation applications. If specific ISYNC functions are required that are not covered, then the user can set the corresponding system variables using the existing function module MC_ReadParameter_MDX or MC_WriteParameter_MDX (MPLCMotion_MDXlibrary). The MC_LinkTecGear_MDX function module is mandatory as central data interface to the gear technology function, for example to administer the non-remanent system variables of the ISYNC technology function. Besides, the technology function "Internal synchronous operation" is enabled with MOVIDRIVE B. 3.3.3 Startup cycle and offset types You can define whether the startup cycle or offset travel is to be performed time-related or position-dependent. The choice whether the synchronization process is to be performed in a time-related or position-dependent manner is defined for the startup cycle through the input GearInMasterDistance of the MC_PrepareGearIn_MDX function module. In the case of offset travel, the choice whether the time-related or position-dependent synchronization process is to be used is made using the input GearOffsetMasterDistance of the MC_PrepareGearOffset_MDX function module. If the value is "", time-related synchronization process is activated; if the value is unequal "", position-dependent synchronization will be used with the relevant value as master distance for the synchronization process. 36 Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC
MPLCTecGearMotion_MDX Project planning I 3 Time-related startup cycle Time-related startup cycle means the slave synchronizes to the master using the velocity and ramp set in the MC_SetGearDynamics_MDX function module. It these values are set more dynamically than those for the master, then a lag error that might occur during the stop cycle can be reduced. n [1] [2] [3] [4] [5] [6] t 61685AXX [1] Velocity set with MC_SetGearDynamics_MDX [2] Velocity of the slave [3] Velocity of the master [4] Start of the time-related startup cycle [5] Ramp set with MC_SetGearDynamics_MDX (with reference to 3 1/min) [6] Slave is in sync with the master Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC 37
I MPLCTecGearMotion_MDX 3 Project planning Position-dependent startup cycle Position-dependent startup cycle means the slave synchronizes to the master within a master distance that can be set. The startup cycle is softer than with time-related startup cycle but a lag error cannot be reduced. The position-dependent startup cycle depends on the direction. This means, if the master distance is specified on the input GearInMasterDistance as positive value for the startup cycle, then the master also has to turn in positive direction, else there will not be a startup cycle process. n [1] [2] [3] [4] [5] [6] 61686AXX [1] Velocity of the master [2] Velocity of the slave [3] Start of the position-dependent startup cycle [4] Master distance for the startup cycle [5] Slave is in sync with the master [6] Position of the master 38 Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC
MPLCTecGearMotion_MDX Project planning I 3 3.3.4 Various start events for startup cycle and offset travel The MC_PrepareGearIn_MDX and MC_PrepareGearOffset_MDX function modules can be used to set the event that triggers the action independent of the chosen startup cycle or offset type. During the startup cycle, this is set with the input GearInStartSource on the MC_PrepareGearIn_MDX function module. Startup cycle events Possible startup cycle events: MDX_GEAR_DIRECT The startup cycle is directly started with the MC_GearInDirect_MDX function module. MDX_GEAR_INTERRUPT_DI2/MDX_GEAR_INTERRUPT_X14C The startup cycle is started by an interrupt event that is triggered by a signal change on binary input DI2 of the MOVIDRIVE B unit or the C track of the external encoder on X14. A delayed startup cycle can be implemented using the input Distance- ForStartGearIn ( following figure).

MPLCTecGearMotion_MDX Project planning I 3 Offset processing An offset can be activated during synchronous operation after a successfully completed startup cycle. Offset means the slave moves faster or slower than a set value and then moves in sync with the master again. Any phase shift can be implemented in this way. The start event for offset processing is chosen with the input GearOffsetStartMode on the MC_PrepareGearOffset_MDX function module. Possible settings: MDX_GEAR_DIRECT Offset processing is directly started with the MC_GearOffsetDirect_MDX function module. MDX_GEAR_DISTANCE_COUNTER With this setting, offset processing is started according to the specified master distance. The input OffsetAutoRepeat can be used to specify whether offset travel is to be restarted automatically if the counter reaches the value of DistanceForStartOffset again. n [1] [2] [3] [5] [4] [6] [7] 61689AXX [1] Slave is in sync with the master [2] Offset travel [3] Synchronous operation [4] Begin of offset processing [5] Velocity of the slave [6] Specified master distance for offset processing [7] Position of the master Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC 41
I MPLCTecGearMotion_MDX 3 Project planning 3.3.5 Project planning procedure The function modules of the MPLCTecGearMotion_MDX library are divided into four directories. MDX_Gear_- Config MDX_Gear_Config directory: MC_SetGearConfig_MDX MDX_Gear_Main MDX_Gear_Main directory: MC_LinkTecGear_MDX MC_GearState_MDX MC_GearClearLag_MDX MC_ClearLagPermanent_MDX MDX_Gear_Parameter directory: MC_PrepareGearIn_MDX MC_PrepareGearOffset_MDX MC_SetGearDynamics_MDX MDX_Gear_Parameter MDX_Gear_- SingleAxis MDX_Gear_SingleAxis directory: MC_GearInDirect_MDX MC_GearOutDirect_MDX MC_GearOffsetDirect_MDX Procedure Integrate the MPLCTecGearMotion_MDX library additionally in the MPLCMotion_MDX library into the project using the Library Manager. If the master position is to be transferred via SBus, the MC_InitialConfig_MDX function module has to be configured accordingly. This function module is part of the MPLCMotion_MDX library ( "MPLCMotion_MDX und MPLCMotion_MX Libraries for MOVI-PLC " manual). The SBus should also be synchronized. The SBus synchronization telegram is created with the MC_SetSync_MDX function module (part of the MPLC_Motion_MDX library). If the virtual encoder of the controller is used as master, the SBus will be automatically synchronized by calling the MC_LinkTecAxis_Virtual function module ( MPLCTecVirtualEncoder library). The MC_LinkTecGear_MDX function module constitutes the interface between technology function and motor axis and must be called cyclically in the program. Once the MC_ConnectAxis_MDX function module has established the connection with the motor axis, the MC_LinkTecGear function module activates the technology function "Internal synchronous operation" on the respective motor axis. The MC_SetGearConfig_MDX function module is used to set the general synchronous operation parameters. This function module must be called with a rising edge on the Execute input each time the MOVI-PLC controller is restarted, or if you want to change the general synchronous operation parameters. 42 Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC
MPLCTecGearMotion_MDX Project planning I 3 The MC_Prepare... function module is used to set the required startup cycle and offset modes as well as the associated parameters. NOTE The ramp is also changed when calling the MC_PrepareGearIn_MDX function module. The motor axis engages once the startup cycle event is detected, e.g. interrupt DI2. If positioning is performed after a successful stop cycle (e.g. with the MC_MoveAbsolute_MDX function module), then the LINEAR ramp type is set automatically. If you want to synchronize again, the MC_PrepareGearIn_MDX function module must be called again so that the ramp type is set to synchronous operation even if the startup cycle parameters have not changed. Exception: If synchronization takes place using the MC_GearInDirect_MDX function module and if the startup cycle parameters have not changed, then the MC_PrepareGearIn_MDX function module need not be called again because the MC_GearInDirect_MDX function module changes the ramp type automatically.

MC_PrepareGearIn_MDX function module The MC_PrepareGearIn_MDX function module prepares the startup cycle. The parameters required for the startup cycle as well as the ramp type are set to synchronous operation. However, there is no active engaging. MC_PrepareGearOffset_MDX function module Similarly to the MC_PrepareGearIn_MDX function module, you can set the offset modes and offset parameters using the MC_PrepareGearOffset_MDX function modules. MC_SetGearDynamics_MDX function module The MC_SetGearDynamics_MDX function module is used with time-related startup cycle of offset processing for setting the required catch-up velocity and ramp. Besides, you can set the stop cycle ramp and a free-wheeling speed after completed stop cycle.

I MPLCTecGearMotion_MDX 3 Overview of the MPLCTecGearMotion_MDX library 3.4.2 Restore function for saving MOVIDRIVE system variables The MC_LinkTecGear_MDX function module provides an initialization service. The "Restore" service transfers the image of the synchronization operation configuration on the controller to the MOVIDRIVE unit again once an axis fault has been acknowledged.

Once the MC_ConnectAxis_MDX function module has established the cyclical communication to the motor axis and after enable via the Enable input, the synchronous operation function of MOVIDRIVE B is activated first. Next, the initialization service of the general synchronous operation parameters is executed which is selected using InitService. These synchronous operation parameters are deleted depending on the set service, for example after a fault reset, or the image of the last setting on the controller is transferred to the motor axis. In cyclical operation, the MC_LinkTecGear_MDX function module constitutes the parameter interface of the synchronous operation function modules to MOVIDRIVE. Additionally, various status signals are available as outputs. NOTES The MC_LinkTecAxis_Virtual function module is mandatory for using the synchronous operation function. The function module has to be called cyclically in the program. If the output signal LinkState has the status NotLinked, then none of the function modules of the MPLCTecVirtualEncoder library can be executed. A corresponding error message is issued. Prerequisite MOVI-PLC basic or advanced controller in the technology version T1 or higher. The MC_ConnectAxis_MDX function module is integrated in the cyclical program for the relevant motor axis.

The motor axis leaves synchronization with a rising edge on the Execute input. If the input GearOutFreeRunning = TRUE, the drive turns after decoupling with the velocity set at the FreeRunSpeed input. Else the motor axis remains stopped subject to position control. The GearOutLagCountOn input specifies whether the difference counter is to remain active after the stop cycle. This selection is only possible with stop cycle in position control; when the stop cycle is performed in speed control, the difference counter always remains active. NOTES The lag error can only be reduced after another startup cycle process when it is time-controlled (input GearMasterDistance = with the MC_PrepareGearIn_MDX function module). Setting of the free-wheeling speed is only active once during the stop cycle. The free-wheeling speed can then only be changed with the MC_SetGearDynamics_MDX function module. The current library MPLCTecGearMotion_MDX also allows for "changeover on the fly" from synchronous operation to positioning mode; the output GearState of the MC_LinkTecGear_MDX function module remains set to synchronous operation. This is the reason why the motor axis must be decoupled before it is engaged again. Prerequisite The "Synchronous operation" technology function is created using the MC_LinkTecGear_MDX function module.

I MPLCTecCamMotion_MDX 4 Introduction 4 MPLCTecCamMotion_MDX 4.1 Introduction The MPLCTecCamMotion_MDX library is based on the technology function "Electronic cam" of the MOVIDRIVE MDX61B drive inverter. The following simplifications have been achieved compared to the previous solutions. Before: Decentralized startup and control of the technology function "Electronic cam" Complex familiarization with the SEW-specific programming language IPOS plus Complex programming when networking and synchronizing several linked electronic cams. Program functionality distributed on several inverters, which means complex diagnostics Lengthy familiarization in the event of functional extensions of the existing program sequence Solution with MOVI-PLC : Programming in accordance with IEC 61131, which means customer-specific applications can be easily implemented. Library for controlling the technology function "Electronic cam". No expert knowledge is required for handling the technology function "Electronic cam". Central control of the technology function "Electronic cam." Additional functions can be easily implemented, such as a virtual encoder. NOTE Additional documentation: For general notes on the theory of operation of the library, refer to the "MPLCMotion_MDX and MPLCMotion_MX Libraries for MOVI-PLC " manual "MOVIDRIVE Electronic Cam" manual. 4.2 Project planning 4.2.1 Prerequisites In order to use the MPLCTecCamMotion_MDX library, you need a MOVI-PLC DHP21B controller in application version T1 or higher.

MPLCTecCamSwitch_MDX Introduction I 5 5 MPLCTecCamSwitch_MDX 5.1 Introduction The MPLCTecCamSwitch_MDX library is based on the technology function "Cam controller" of the MOVIDRIVE B drive inverter. The following simplifications were achieved compared to the previous solution approaches. Before: Familiarization in the SEW-specific programming language Special knowledge required for creating the cam controller and setting the relevant parameters. Solution with MOVI-PLC : Programming in accordance with IEC 61131, which means customer-specific applications can be implemented easily. Library for controlling the technology function "Cam controller". Using this library, the cam controller technology function can be configured and controlled easily without detailed knowledge of the individual firmware functions. NOTE Additional documentation: For general notes on the functioning of the library, refer to the "MPLCMotion_MDX and MPLCMotion_MX Libraries for MOVI-PLC " manual. "IPOS plus " manual 5.2 Areas of application The MPLCTecCamSwitch_MDX library is suited for applications where hardware outputs have to be switched quickly depending on a position. Application examples Controlling glue guns in packaging machines Switching valves Properties Up to 8 cam channels (binary outputs DO2 to DO5 of the MOVIDRIVE B basic unit and DO1 to DO13 with MOVIDRIVE B with DIP11B o DIO11B option) can be configured with 4 cams each (switching ranges). The binary outputs must be configured with parameters P62x and P63x to IPOS output in the parameter tree of the MOVITOOLS MotionStudio. The response time of the cam channels (t z ) is 1 ms for binary outputs DO2 to DO5 and 5 ms for binary outputs DO1 to DO13. Each cam channel takes account of the delay (switching delay) of the connected actuator. In this way the switching position is corrected depending on the velocity (quantization.1 ms). The cam controller can be set to the following position sources: All physical encoder inputs of MOVIDRIVE B Virtual encoders of the MOVI-PLC controller Virtual encoder on MOVIDRIVE B Four positions via SBus Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC 143
I MPLCTecCamSwitch_MDX 5 Project planning 5.3 Project planning 5.3.1 Prerequisites In order to use the MPLCTecCamSwitch_MDX library, you need a MOVI-PLC controller in application version T1 or higher. A MOVIDRIVE B unit in standard version (..) is sufficient as drive inverter. The MPLCTecCamSwitch_MDX library must be inserted in the project in addition to the MPLCMotion_MDX library. Also adhere to the prerequisites in the "MPLCMotion_MDX and MPLCMotion_MX Libraries for MOVI-PLC " manual. 5.4 Overview of the MPLCTecCamSwitch_MDX library 6186AXX MC_ForceCamSwitchChannel_MDX function module The MC_ForceCamSwitchChannel_MDX function module is used to set and clear outputs independent of the cam controller. MC_LinkTecCamSwitch_MDX function module The MC_LinkTecCamSwitch_MDX function module constitutes the interface between technology function "Cam controller" and motor axis and must therefore be called cyclically in the program. Once the MC_ConnectAxis_MDX function module has established the connection with the motor axis, the MC_LinkTecCamSwitch_MDX function module activates the cam controller technology function on the respective motor axis. MC_SetCamSwitchConfig_MDX function module The MC_SetCamSwitchConfig_MDX function module is used to configure the cam controller. This function module must be called with a rising edge at the Execute input when the MOVI-PLC controller is started, or when you want to change the parameters of the cam controller. MC_StartCamSwitch_MDX function module The MC_StartCamSwitch_MDX function module is used to activate the cam controller. MC_StopCamSwitch_MDX function module The MC_StopCamSwitch_MDX function module is used to deactivate the cam controller. 144 Manual MPLCTec..._MDX, MPLCTecVirtualEncoder Libraries for MOVI-PLC

MPLCTecCamSwitch_MDX Overview of the MPLCTecCamSwitch_MDX library I 5 State transitions 4, 5 and 6 are triggered by the MC_SetCamSwitchConfig_MDX function module. This function module initializes and writes the parameters of one of the four cam channels. When the function module is executed for the first time after the logical connection to the motor axis has been established, the function module will trigger one of the three state transitions. The technology function "Cam controller" is then in the state GEN_TEC_INITIALIZED. The cam controller can only be activated when the required parameters have been initialized. The MC_StartCamSwitch_MDX function module can therefore only be executed without errors if the LinkState output has one of the two values GEN_TEC_RESTORED or GEN_TEC_INITIALIZED.
