Step and direction with AKD
I got an AKD moving at the moment with a step and direction input from a PLC. The input resolution I'm currently using is 1000 counts/rev and no gear ratio (1:1). Input type 1 (step and direction signals) and input source 2 (Feedback source X7) are used in this setup. While trying to get the this system to run smoothly I stumbled on a few problems. The input pulse coming from the PLC has a maximum of 40kHz. This output pulse limits the smoothness of the system I'm trying to get this system to run as smooth as possible. Changing the PLC is not an option due to customer requirements.
Is there a way to get the resolution of the drive down or up the resolution somehow from the PLC without losing the accuracy?

If you cannot increase the resolution of the step command, you only have one other choice, to use the filter "PL.FILTERTIME". PL.FILTIMER will help smooth out the motor's velocity while being commended to move.
