Uzk fault on E/R module

alexmac_uk Posts: 118 Rating: (1)	Hi all, I am working on a 5 axis cnc machine. 840d controller. Simodrive 611. Just replaces the e/r module due to not being able to remove emergency stop. New e/r module seemed to be working ok until I began to run a program. The Z axis travelling down causes a red light to come on the e/r module. Can only reset by powering down. If I change MD setting 30200 max ax velo from 20,000mm/min to 5,500mm/min it works ok but is a lot slower. I think maybe the power module is faulty? The Y axis is also on the same measuring card and power module. Any ideas?

How high is your incoming voltage, and is it balanced phase to ground?
