This is however open loop.. as if driving a stepper motor. You will not be able to make a closed loop system through the PLC, but you can create coding to monitor the drive or motor progress. PLC coding can then compare what you are asking and what you are getting. Note that some drives already have motion control built in. You can trigger the position via a digital signal or by communication (like CAN or Modbus). Many drive also have the ability to have extra communication modules for Profibus or such. For my purposes the built in pulse and direction worked well enough. TIP: make sure of the type signal required ( NPN / PNP / differential; 5V / 24V ). Does this help you? w
