14 1 Introduction Interfaces Standard available interfaces. DC power supply voltage The supply voltage VDC supplies the drive and control electronics and the power stage via a 4-position M12 (male, B-coded) connector. This connector also supplies interface to 12 to 24V Aux-Power input to supply power to logic circuits in the event of main supply loss. The ground connections of all interfaces are galvanically connected. For more information see chapter 5.2 Ground design. This chapter also provides information on protection against reverse polarity. Multifunction interface The multifunction interface operates at the following signal levels: 24V input signals are opto-isolated Signal output is opto-isolated and current limited 0 to 10V analog signal is not isolated The 24V input signals are programmable as general purpose or to predefined functions. The output is a special function as a high speed trip output. The reference voltage or current is applied to the analog input can be used for a number of programmatically defined operations. Interface is accomplished via a 12-position M12 (male, A-coded) connector. Ethernet interface The service interface provides a connection to an Ethernet network via a 4-pin M12 (female, D-coded) connector. The commissioning software may then be used to configure the device IP address and subnet mask. The Ethernet interface is also used for firmware upgrades. Protective earth Protective earth provides a means of grounding to the device chassis. 6

Power supply Use only power supply units that are approved for over-voltage category III. Wiring Use only 60/75 C copper conductors. SIL PFH at high demand or continuous demand < < < <10-5 HFT and SFF Depending on the SIL for the safety system, the IEC standard requires a specific hardware fault tolerance HFT in connection with a specific proportion of safe failures SFF (safe failure fraction). The hardware fault tolerance is the ability of a system to execute the required safety function in spite of the presence of one or more hardware faults. The SFF of a system is defined as the ratio of the rate of safe failures to the total failure rate of the system. According to IEC 61508, the maximum achievable SIL of a system is partly determined by the hardware fault tolerance HFT and the safe failure fraction SFF of the system. SFF HFT type A subsystem HFT type B subsystem < 60% SIL1 SIL2 SIL3 SIL1 SIL2 60%... <90% SIL2 SIL3 SIL4 SIL1 SIL2 SIL3 90%... < 99% SIL3 SIL4 SIL4 SIL2 SIL3 SIL4 99% SIL3 SIL4 SIL4 SIL3 SIL4 SIL4 Fault avoidance measures Systematic errors in the specifications, in the hardware and the software, usage faults and maintenance faults of the safety system must be avoided to the maximum degree possible. To meet these requirements, IEC specifies a number of measures for fault avoidance that must be implemented depending on the required SIL. These measures for fault avoidance must cover the entire life cycle of the safety system, i.e. from design to decommissioning of the system. 30

39 4 Basics 4 Basics Functional safety Automation and safety engineering are two areas that were completely separated in the past but recently have become more and more integrated. Engineering and installation of complex automation solutions are greatly simplified by integrated safety functions. Usually, the safety engineering requirements depend on the application. The level of the requirements results from the risk and the hazard potential arising from the specific application Working with IEC IEC standard The standard IEC Functional safety of electrical/electronic/programmable electronic safety-related systems covers the safety-related function. It is not only one single component but the entire function chain (e.g. from the sensor through the logical processing unit to the actuator) that is considered as one single unit. This function chain must meet the requirements of the specific safety integrity level as a whole. Systems and components that can be used in various applications for safety tasks with comparable risk levels can be developed on this basis. SIL, Safety Integrity Level The standard IEC defines 4 safety integrity levels (SIL) for safety functions. SIL1 is the lowest level and SIL4 is the highest level. A hazard and risk analysis serves as a basis for determining the required safety integrity level. This is used to decide whether the relevant function chain is to be considered as a safety function and which hazard potential it must cover. Draft V PFH, Probability of a dangerous hardware failure per hour To maintain the safety function, the IEC standard requires various levels of measures for avoiding and controlling faults, depending on the required SIL. All components of a safety function must be subjected to a probability assessment to evaluate the effectiveness of the measures implemented for controlling faults. This assessment determines the PFH (probability of a dangerous failure per hour) for a safety system. This is the probability per hour that a safety system fails in a hazardous manner and the safety function cannot be correctly executed. Depending on the SIL, the PFH must not exceed certain values for the entire safety system. The individual PFH values of a function chain are added; the total PFH value must not exceed the maximum value specified in the standard. 31

41 5 Engineering 5 Engineering 5 This chapter contains information on the application of the product that is vital in the design phase. 5.1 External power supply units MULTI-MODE OPERATION This device will operate differently in each mode of operation. It is critical that all documentation be read completely. A clear understanding of how the device is to be employed must be present before attempting to install or commission the device. Failure to follow these instructions can result in equipment damage. ELECTRIC SHOCK CAUSED BY INCORRECT POWER SUPPLY UNIT The VDC, AUX_PWR and INPUT_REFERENCE supply voltages are connected with many exposed signal connections in the drive system. z Use a power supply unit that meets the PELV (Protective Extra Low Voltage) requirements. z Connect the negative output of the power supply unit to PE (ground). Failure to follow these instructions will result in death or serious injury.! CAUTION GENERAL POWER SUPPLY PRACTICE Do not connect or disconnect the power supply while power is applied. Disconnect the AC side to power down the DC supply. For battery operated systems connect a transient suppressor across the switch to prevent arcs and high-voltage spikes. Failure to follow these instructions may result in damage to system components! 33

42 5 Engineering Supply voltage +VDC General The power supply unit must be rated for the power requirements of the drive. The input current can be found in the technical data. The actual power requirements are often significantly lower because the maximum possible motor torque is usually not required for normal operation of a system. When designing the system, note that the input current of the drive is higher during the motor acceleration phase than during constant movement. Regeneration condition (back EMF) Note the following for drives with large external mass moments of inertia or for highly dynamic applications: Motors return regeneration energy during deceleration. The DC bus can store a limited amount of energy in the capacitors. Connecting additional capacitors to the DC bus increases the amount of energy that can be stored. If the capacity of the capacitors is exceeded, the excess energy must be discharged via internal or external braking resistors. Overvoltage conditions can be limited by adding a braking resistor with a corresponding braking resistor controller. This converts the regenerated energy to heat energy during deceleration. LOSS OF CONTROL DUE TO REGENERATION CONDITION Regeneration conditions resulting from braking or external driving forces may increase the VDC supply voltage to an unexpected level. Components not rated for this voltage may be destroyed or cause malfunctions. Verify that all VDC consumers are rated for the voltage occurring during regeneration conditions (for example limit switches). Use only power supply units that will not be damaged by regeneration conditions. Use a braking resistor controller, if necessary. Failure to follow these instructions can result in injury or equipment damage. 34

43 5 Engineering Power supply cabling EMI and RFI! CAUTION These recommendations will provide optimal protection against EMI and RFI. The actual cable type, wire gauge, shield type and filtering devices used are dependent on the customer s application and system. The length of the DC power supply cable to an MDrive should not exceed 50 feet (15.2 m). Always use shielded/twisted pairs for the Lexium MDrive DC supply cable. Failure to follow these instructions may result in damage to system components! Cable length, wire gauge and power conditioning devices play a major role in the performance of your Lexium MDrive. Figure 5.1 illustrates the recommended cable configuration for DC power supply cabling under 50 feet (15.2 m) long. If cabling of 50 feet (15.2 m) or longer is required, the additional length may be gained by adding an AC power supply cable (see Figures 5.2 and 5.3). Correct AWG wire size is determined by the current requirement plus cable length.

45 5 Engineering Auxiliary power supply The auxiliary logic supply is an optional power supply used to provide power to the logic circuitry of the Lexium MDrive in the event of main system power failure. This supply will retain data such as position. There are no special considerations required when choosing this supply beyond: Voltage to +24 VDC Current ma per Lexium MDrive Wiring and shielding Noise is always present in a system that involves high power and small signal circuitry. Regardless of the power configuration that you use in your system, there are some wiring and shielding rules that you should follow to keep your noise-to-signal ratio as small as possible. Rules of wiring Power Supply and Motor wiring should be shielded twisted pair, and these lines should not run parallel to signal carrying wires. For installations which utilize separate electric motor drives and stepper motors, wiring between the driver and motor should be shielded twisted pairs using 20 gauge wire for motor current less than 4.0 amps and 18 gauge or better for motor current 4.0 amps or higher. A common mode choke may be required in each of the motor phase lines to reduce shield current levels. Power ground return should be as short as possible. Power Supply wiring should be shielded twisted pairs. Use 18 gauge wires if load is less than 4 amps, or 16 gauge for more than 4 amps. Never use a daisy-chain power supply wiring scheme to system components. This type of power distribution will result in degraded system reliability and performance as a result of poor EMC and ground-loop issues. In cases where daisy-chaining is unavoidable, the systems engineer is responsible for final system reliability and performance. The use of conservatively selected wire gauge and the use of decoupling capacitors (i.e. a combination of capacitors to provide for acceptable low frequency and high frequency noise reduction) at each electronic drive should be considered as a minimum. Rules of shielding The shield must be tied to zero-signal reference potential. In order for shielding to be effective, it is necessary for the shield to be earthed or grounded. The shield must be connected so that shield currents drain to signal-earth connections. The shield should be tied to a single point to prevent ground loops 37

47 5 Engineering 5.2 Ground design The ground connections of all interfaces are galvanically connected, including the ground for the VDC supply voltage. The multifunction interface is an exception to this in the case of devices with galvanic isolation. The following points must be considered when you wire the drives in a system: The voltage drop in the VDC power supply lines must be kept as low as possible (less than 1 V). At higher ground potential differences between different drives, the communication / control signals may be affected. If the distance between the system components is greater, it is recommended to use decentralized power supply units close to the individual drives to supply the VDC voltage. However, the ground connections of the individual power supply units must be connected with the largest possible conductor cross section. If the master controller (e.g. PLC, IPC etc.) does not have galvanically isolated outputs for the drives, you must verify that the current of the VDC supply voltage has no path back to the power supply unit via the master controller. Therefore, the master controller ground may be connected to the VDC supply voltage ground at a single point only. This is usually the case in the control cabinet. The ground contacts of the various signal connectors in the drive are therefore not connected; there is already a connection via the VDC supply voltage ground. If the controller has a galvanically isolated interface for communication with the drives, the ground of this interface must be connected to the signal ground of the first drive. This ground may be connected to a single drive only to avoid ground loops. This also applies to a galvanically isolated CAN connection. Equipotential bonding conductors Potential differences can result in excessive currents on the cable shields. Use equipotential bonding conductors to reduce currents on the cable shields. The equipotential bonding conductor must be rated for the maximum current flowing. Practical experience has shown that the following conductor cross sections can be used: AWG 4 (16 mm 2 ) for equipotential bonding conductors up to a length of 650 ft (200 m) AWG 4 (20 mm 2 ) for equipotential bonding conductors with a length of more than 650 ft (200 m) 39

48 5 Engineering 5.3 Monitoring functions The monitoring functions in the product can help to guard the system and reduce the risks involved in a system malfunction. These monitoring functions may not be used to protect persons. The following monitoring functions are available and be monitored by two methods: 1) Software: may be monitored using software via the service interface 2) Hardware: may be monitored using the signal outputs via the multifunction interface. 40

49 6 Installation 6 Installation 6 LOSS OF CONTROL The designer of any control scheme must consider the potential failure modes of control paths and, for certain critical functions, provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are EMERGENCY STOP, overtravel stop, power outage and restart. Separate or redundant control paths must be provided for critical functions. System control paths may include communication links. Consideration must be given to the implication of unanticipated transmission delays or failures of the link. Observe all accident prevention regulations and local safety guidelines. 1) Each implementation of the product must be individually and thoroughly tested for proper operation before being placed into service. Failure to follow these instructions can result in death or serious injury. 1) For USA: Additional information, refer to NEMA ICS 1.1 (latest edition), Safety Guidelines for the Application, Installation, and Maintenance of Solid State Control and to NEMA ICS 7.1 (latest edition), Safety Standards for Construction and Guide for Selection, Installation and Operation of Adjustable-Speed Drive Systems. RISK OF INJURY WHEN REMOVING CIRCUIT BOARD PLUGS z When removing them note that the connectors must be unlocked. Supply voltage VDC: Unlock by pulling at the plug housing Miscellaneous: Unlock by pressing the locking lever z Always hold the plug to remove it (not the cable).
