PID Control for Inverter controlled motor

[miketheb]

Hi All

Has anyone used the PID function for controlling an inverter controlled motor to give set lengths of travel through a gearbox drive i.e.

Motor needs to run for say 10000 pulses (from an encoder using high speed input) and then come to a slow stop, the length dependant on the number of pulses.

Then repeat with pulses set by a programme register?

I assume it can be done and am about to try ~ any issues likely to cause a problem. PLC is Mitsi FX2N

Assuming your inverter does not have a positioning front end, you will need a single axis controller for your PLC. Take the speed and direction outputs to your inverter.
