3 FAMILY Glossary of Terms 3 GLOSSARY OF TERMS Brushless DC Motor Hall Effect Sensor JST LED Load MDR Normally Open / Normally Closed NPN / PNP Photo-sensor PLC PWM Retro-reflective / Reflex A D.C. motor with a permanent magnet rotor and coils in the stator. The stator coil currents are sequenced by an external brushless D.C. motor controller. In such motors, current and torque, voltage and rpm are linearly related. The main advantage to this type of motor is the elimination of EMI caused by the arcing brushes and improved motor life. Special sensor embedded within the brushless DC motor of an MDR used to provide motor rotor position feedback to the motor controller This is the name of a particular connector manufacturer that produces a specific plug/socket arrangement for MDR connection to control cards. This name is accepted within the conveyor and MDR industry as a simple description of the particular socket style used on EZ-24 Family hardware. Light Emitting Diode In the context of this document, LED s are used on the EZ-24 Family controllers to provide visual indication of module status A separate (usually wrapped or boxed) object to be transported by the conveyor. The terms tray, tote, or carton may also be used interchangeably in this document. Motorized Drive Roller or Motor Driven Roller - Brushless DC motor and gearbox assembly integrated into a single conveyor roller. Control logic terminology to define the state of the output of a Boolean on or off device. The term specifically describes the state of the output circuit when the device s sensing circuit is un-energized. In the context of photo-sensors; a normally open wired sensor would have its output circuit energized when it detected its reflected light and its output circuit would be de-energized when it did not detect its reflected light. Conversely a photo-sensor wired normally closed would energize its output circuit when it did not see its reflected light and it would de-energize its output circuit when it did detect its reflected light. Electronics term that indicates the type of transistor circuit used for a logical input or output for controllers. NPN devices will provide a common or ground connection when activated and a PNP device will provide a logic voltage connection when activated. A device, mounted near the end of the conveyor zone to sense the presence of a load on the zone Programmable Logic Controller A wide variety of industrial computing devices that control automatic equipment Pulse Width Modulation a control scheme that utilizes high speed switching transistors to efficiently deliver power in a controlled fashion from EZ-24 Family controllers to MDR. Term used to describe the two basic types of photo-sensors. Retro-reflective photosensors utilize a reflective target that must be aligned with the photo-sensor such that the light emitted by the photo-sensor is reflected back to it. Reflex (or sometimes known as proximity) type photo-sensors emit light to be reflected back from an object located sufficiently close to the sensor. For both types of photo-sensors, when they detect their reflected light source, their signaling output circuit changes state.

4 FAMILY Slave Rollers Zone A set of non-motorized conveyor rollers mechanically linked to an MDR. The MDR and slave rollers make up a physical zone. All of the slave rollers in a zone rotate at the same speed and direction as the MDR because of their mechanical linkage A basic (linear or curved) cell of the conveyor consisting of a set of slave rollers driven by one or more MDR s and a single photo-sensor.

If the speed setting of the module is set to 100% PWM, then this will be the value of the current seen at the MDR. For speed settings less than 100% PWM, the actual current seen at the motor will be proportionally higher. At very low speed settings with high torque loads, the starting current seen at the MDR may reach the peak current limit of the module. 2 Important Note on Rated Current: The values shown for Rated Current for each MDR selection is the current seen at the MDR when the speed is set to 100% PWM. Under continuous running conditions at 100% PWM; this is the current at which the module s built in current limiting mechanisms will not engage to limit the current and the MDR will not over-heat. At speeds less than 100% PWM, the actual current seen at the MDR will increase and continuous running at speeds less that 100% PWM will eventually result in the module s built in current limiting mechanisms to engage to limit the current to the motor to prevent overheating.

25 FAMILY EZ-24 Switch Settings 25 DIP SW POSITIONS 9 & 10 ELECTRICAL BRAKE SELECTION Braking Method SW 9 SW 10 Standard Dynamic Braking OFF OFF Free ON OFF Servo Lock 1 OFF ON Servo Lock 2 ON ON Please note that these settings are for electrically controlled braking of MDR. Some MDR s utilize an optional mechanical brake used to hold the MDR in its stopped position. Mechanical brakes are fail-safe in that they must be energized to release and de-energized to engage braking. Only EZ-24HTB and EZ-24HTBS provides 24VDC output to energize mechanical brake The following table defines the MDR Braking Methods available: Method Standard Dynamic Braking Free Servo Brake 1 Servo Brake 2 Description Standard Dynamic braking - MDR power circuit in EZ-24 is internally shunted to ground during motor stop sequence in order to bring the rotor to a stop. This is the MDR industry standard braking method. MDR power circuit in EZ-24 is internally disconnected and made an open circuit to allow the rotor to free spin until its mechanical load brings it to a stop. When run signal is removed; the EZ-24 utilizes the MDR s Hall Effect sensors to determine the position of the rotor and will inject current into the motor windings to maintain rotor position. Servo Brake 1 utilizes 2 of the EZ-24 s power transistors for current injection. Same as Servo Brake 1 except that Servo Brake 2 utilizes 3 of its power transistors for current injection. Do Not use Servo Brake 1 or Servo Brake 2 settings for MDR s with mechanical brake. Doing so will result in damage to MDR and/or EZ-24HTB / HTBS module.

29 FAMILY EZ-24 Family Wiring Considerations 29 EZ-24 FAMILY WIRING CONSIDERATIONS The EZ-24 family of products can be used in a wide variety of connection configurations; however care in selection of the proper version of module should be taken based upon the intended use. RUN INPUT SIGNAL WIRING The primary item to consider is the effect of the controlling circuit (PLC Output for example) and its response to the EZ-24 s PNP/NPN auto-detection circuitry for RUN and REVERSE input signals. SOLID-STATE PLC OUTPUT MODULES The wiring method can sometimes produce unexpected results when used with solid-state PLC outputs when there is the possibility of the solid-state PLC output module being powered off while the EZ-24 module remains powered. Depending on the PLC s solid-state output circuitry, its powered-off state can provide a sufficient reverse current path that will allow enough current to flow to cause the EZ-24 to detect a positive RUN or REVERSE input. The unexpected result is that the EZ-24 could run its MDR without its RUN signal being energized by the PLC controls. Please note that this condition is only applicable for EZ-24 and EZ-24HTB Please note that this condition only occurs if the solid-state PLC Output module is removed from power while the EZ-24 remains powered. If the EZ-24 and PLC Output modules share the same power disconnecting means, then this condition will not occur. Please note that this condition does not occur with relay or dry contact style PLC output modules. Any one of the following actions will eliminate this unexpected behaviour from solid-state PLC output control of the affected EZ-24 family modules: Utilize relay or dry contact style PLC Outputs in lieu of solid-state Assure that EZ-24 and PLC output module share the same power disconnect means such that PLC Output module and EZ-24 are always disconnected from power at the same time Insert a blocking diode in series between the solid-state PLC output and EZ-24 RUN signal. Utilize EZ-24-HTBS module

33 FAMILY EZ-24 Family Wiring Considerations 33 SINGLE EZ-24HTBS RUN SIGNAL WIRING The EZ-24HTBS accommodates solid state PLC output without the need for adding a blocking diode. However, the EZ-24HTBS is restricted for use with sourcing outputs only. The following are acceptable and unacceptable RUN signal wiring examples for EZ-24HTBS: FIGURE 8 EZ-24HTBS RUN SIGNAL NOT ALLOWED WITH SINKING PLC OUTPUT

34 34 EZ-24 Reference Manual FAMILY FIGURE 9 - EZ-24HTBS RUN SIGNAL IS ALLOWED WITH SOURCING SOLID STATE OR RELAY PLC OUTPUT MULTIPLE EZ-24 S CONTROLLED FROM SINGLE PLC OUTPUT Some applications require that multiple EZ-24 modules be controlled from a single RUN signal from a single PLC output. This would be useful and convenient in applications where multiple MDR s need to run in unison for a single conveyor section. Similar potential conditions arising from the auto-detect circuitry as described above can produce unexpected results.

36 36 EZ-24 Reference Manual FAMILY FIGURE 12 - EZ-24 / EZ-24HTB AND SINKING PLC OUTPUT ALLOWED WITH BLOCKING DIODES AS SHOWN MULTIPLE EZ-24HTBS RUN SIGNAL WIRING EZ-24HTBS allows for multiple RUN signals parallel wired from a single sourcing PLC output without the need for blocking diodes. As with a single EZ-24HTBS however; PLC output is limited to sourcing only and the EZ-24HTBS will not detect a sinking PLC output signal. FIGURE 13 - EZ-24HTBS WITH SOURCING PLC OUTPUT

37 FAMILY EZ-24 Family Wiring Considerations 37 ERROR OUTPUT SIGNAL WIRING The Error Output signal can be either a PNP or NPN signal that is user selectable via DIP Switch 4. Any single module from the entire EZ-24 family can have its particular Error signal wire to a single PLC input without any special considerations. However, there are special considerations for applications where multiple Error signals need to be wired in parallel to a single PLC input and these differ depending on which specific EZ-24 family module is being utilized. MULTIPLE ERROR SIGNALS FOR EZ-24 FIGURE 14 - NO PARALLEL ERROR SIGNALS FOR EZ-24 WITHOUT BLOCKING DIODES Please note that parallel wiring multiple EZ-24 Error signals to a single point can result in damage to one or all of the connected modules.

Please refer to section Error! Not a valid result for table. beginning on page 55 for detailed instructions. DIP Switch #4 MUST be set to PNP setting for ERROR out to operate for EZ-24HTB and EZ- 24HTBS regardless of single module or multiple parallel wired modules configurations. For EZ-24HTB and EZ-24HTBS; NPN switch setting for DIP switch #4 will not produce an ERROR output signal regardless of single module or multiple parallel modules connections.

40 40 EZ-24 Reference Manual FAMILY ANALOG SPEED CONTROL INPUT WIRING For analog speed control to be enabled DIP Switch #2 must be set to OFF and the Speed Selector Switch must be set to 0. The EZ-24 must also have its RUN signal energized in order for it to act upon the variable voltage applied to the 0-10V terminal. Also please note that if external control of the direction of the motor is desired, a corresponding +24V must also be applied to the REVERSE terminal. FIGURE 18 - ANALOG SPEED CONTROL WIRING Please note that +24V signals for RUN and REVERSE as shown in Figure 18 are applicable to all EZ-24 Family modules. For all modules except EZ-24HTBS, 0V connections for RUN and REVERSE will also work because of the NPN/PNP auto-sensing input signal feature. The EZ- 24HTBS will only operate with +24V applied to RUN and REVERSE signals. Please note that 0 to 10V analog input corresponds to 0 to 100% speed. CONFIGURING ZERO VOLTAGE INPUT TO NON-ZERO SPEED Some analog input applications require that a minimum running speed be established for a 0 voltage analog input. For PLC applications using an analog output, this can be done programmatically. For hard-wired solutions utilizing a speed potentiometer (pot), setting a fixed non-zero speed for a 0 volt analog input requires adding 2 external resistors in conjunction with the external speed pot. Figure 19 shows such a circuit arrangement with 2 resistors and 1 speed pot. The values of the resistors shown are based upon utilizing a 10K Ω speed pot and the desire to fix the minimum speed at 25% of full speed. For speed pots with different resistance value, the 2 resistors shown need to change their values by the same proportion. For example, the values below are for a 10K Ω speed pot; if a 50K Ω speed pot is used, then the 2 resistor values need to be multiplied by 5.

41 FAMILY EZ-24 Family Wiring Considerations 41 FIGURE 19 - ANALOG CIRCUIT TO SET NON-ZERO SPEED FOR ZERO VOLT INPUT Please note that RUN and REVERSE connections are not shown in Figure 19 for clarity. Please refer to Figure 18 for RUN and REVERSE connection detail. For a 10% minimum speed with a 10K W speed pot, change R1 to 15.5KΩ and R2 to 1.1KΩ. Please consult Insight Automation for other minimum speed setting resistor values.

55 FAMILY Speed Out Operation 55 SPEED OUT OPERATION Pin 5 on CN-3 provides a speed output signal whose on/off pulse frequency is proportional to the motor s actual Hall Effect sensor s signal frequency, thus proportional to the rotational speed of the motor. However, the frequency of the Speed Output signal is dependent both upon the motor type selected and the particular EZ-24 family module being used. MDR # of Motor Poles Electrical Frequency at Rated Speed (100% setting) 28 Watt Hz 35 Watt Hz 50 Watt Hz Senergy ECO Hz Senergy BOOST Hz FOR EZ-24 MODULES The Speed Out is determined by the following equation: Speed Out [Hz] = Electrical Frequency [Hz] # of Motor Poles For example, for a Senergy ECO MDR set to run at 50% speed, its Electrical Frequency is 50% of 483 Hz which is Hz. From the above formula, the Speed Out in Hz will be: Speed Out [Hz] = = 24.2 Hz Most typically, you will have the frequency of the Speed Out signal and want to know the percentage of maximum speed the motor is running. Motor Speed [% of Rated] = 100 Speed Out Frequency # of Motor Poles Rated Frequency For a Senergy BOOST MDR whose Speed Out is measured to be 30 Hz: FOR EZ-24HTB AND EZ-24HTBS Motor Speed [%] = 100 = 85.7% 350 The Speed Out frequency is equal to the Electrical frequency: Speed Out [Hz} = Electrical Frequency [Hz] Most typically, you will have the frequency of the Speed Out signal and want to know the percentage of maximum speed the motor is running.

56 56 EZ-24 Reference Manual FAMILY Motor Speed [% of Rated] = 100 Speed Out Frequency Rated Frequency For a 50 Watt MDR whose Speed Out is measured to be 95 Hz: Motor Speed [%] = = 68% Please note that for EZ-24HTB and EZ-24HTBS, you can change the Speed Output terminal to provide a digital motor running signal instead of the frequency-based signal as described above. Please see section Motor Running Signal for Speed Output Jumper on page 57 for details.

57 FAMILY EZ-24HTB & EZ-24HTBS Jumper Settings 57 EZ-24HTB & EZ-24HTBS JUMPER SETTINGS This section pertains to EZ-24HTB and EZ-24HTBS modules ONLY. There are no user settable jumper modifications available for EZ-24 modules Modifying internal jumper settings involves removing the module s plastic housing cover. Handling of EZ-24 with or without the plastic cover must only be performed by personnel who have been adequately electro-statically discharged. Handling EZ-24 module with cover removed without proper ESD precautions may result in module damage. MOTOR RUNNING SIGNAL FOR SPEED OUTPUT JUMPER SETTING By default, EZ-24HTB and EZ-24HTBs provide mechanical brake release control to Pin 9 of the motor JST connector and a motor running frequency-based varying signal on the Speed Output terminal. The Speed Output terminal can be modified to provide a digital motor running signal instead of the default frequency-based output. However, because this signal and the mechanical brake control output share common circuitry, to enable the motor running digital output on the Speed Output terminal; the mechanical brake control must be disconnected. Figure 20 shows the default jumper settings and Figure 21 shows the jumper settings to configure the Speed Output to provide a digital motor running signal while at the same time disabling the mechanical brake release function to Pin 9 of the motor JST connector. Making this jumper change will disable the mechanical brake control. If you connect a motor roller with a mechanical brake and try to run, you may damage the module

60 60 EZ-24 Reference Manual FAMILY ERROR OUTPUT JUMPER SETTINGS By default, EZ-24HTB and EZ-24HTBS modules are shipped from the factory with the ERROR output configured to be PNP (sourcing) which is intended for a sinking PLC input card. This default configuration is depicted in the example wiring shown in Figure 17 on page 39. Figure 22 shows the factory default jumper settings for the PNP (Sourcing) ERROR output signal. FIGURE 22 - DEFAULT ERROR OUTPUT JUMPER SETTINGS For the default jumper configuration shown in Figure 22, DIP Switch #4 MUST be set to PNP setting for ERROR output to operate for any single module or parallel wired modules configuration. NPN switch setting will not produce ANY ERROR output signal for single or parallel connection.

61 FAMILY EZ-24HTB & EZ-24HTBS Jumper Settings 61 For applications or situations where the ERROR output signal needs to connect to a sourcing type PLC input point, then the ERROR output needs to be configured as a sinking circuit. Figure 23 shows the jumper configuration for an NPN (Sinking) ERROR output signal. FIGURE 23 - JUMPER SETTING FOR NPN (SINKING) ERROR OUTPUT SIGNAL For the default jumper configuration shown in Figure 23, DIP Switch #4 MUST be set to NPN setting for ERROR output to operate for any single module or parallel wired modules configuration. PNP switch setting of DIP Switch #4 will not produce ANY ERROR output signal for single or parallel connections.
