When I power on any of my 4 servos (DMM DYN4 1.8KW) the 101keyboard stops functioning. The on-screen keys continue to work. I am referring to the Centroid touchscreen workstation.

Couple more updates, I have the DMM servo drives all wired up, next up wire in MPG pendant (10 switches, one mpg dial, resolution dials.

It has an in/out Neutral. Also they have an earthground which has a terminal soldered to casing.

Progress report, installed Z Axis servo today, milled, drilled, rigid tapped mounting plates for EMC/EMI filters. They do have a terminal for a neutral, and the machine does not have a neutral. Need to contact tech support and find out if it can be omitted. Anyone know?

Thanks, I owned a ul508a panel shop/automation business for many years.. I hear your thoughts

Thanks appreciate it!
