View Full Version : Wanted: Parker CD20 Stepper Drive

Hi Guys,

I wonder if anyone might have a working or believed to be working Parker CD20 stepper drive? I have 1 in a machine at the moment and the axis it controls is playing up. After a bit of process of elimination technique I've come to the conclusion that the drive might be faulty, though its not showing any of the fault lights on the panel. The machine has 2 axis, but unfortunately the second drive is a CD40, which drives a much bigger motor, so swapping them to test might cause me more trouble. I've considered trying a newer drive in its place, but I think that there is some sort of feedback to the original controller, which suspends the program should a fault occur.
