I defined PID settings to control a motor using the Galil DMC2020. I was able to control the position of this motor very precise.

Now I wanted to use a Galil controller DMC2230 to control 3 similar motors but I can not find PID settings which allow me to reach the same precision.

A difference between the first and the second set-up is the servo loop update rate. In the first setup it was 125�s (using the ceramic firmware), in the second setup it is 1000�s (normal firmware). Is this slower servo loop update responsible for the fact that I can not reach the same precision? Or should this not have any effect and should I be able to reach the same precision?

kind regards,
Thomas
