I'm controlling a stacked piezo using step/direction signals. Due to the hysteresis this is not optimal and a closed loop control would be nice. As far as I know, the DMC-40x0 is not able to do this. But searching the Galil website, I found application note 5532 and the CL command, which covers exactly this case. Sadly my firmware doesn't know the command and I am not able to figure out to which controllers the application note applies. The reference for the CL command just mentions "CLS", what ever this is. Is there a chance to get this feature running on a DMC-40x0, may be with an alternative firmware?

Hi Jan,

The CL command is a part of Galil's Closed Loop Stepper firmware. This is a firmware option that can be ordered for your controller. Please email me directly at kushal p at galilmc dot com. We can discuss the details of your application, and I can explain how you can use the closed loop stepper firmware.
