Thanks for the info Al, but I dont think that is the problem. (although I have learned to do a machzero X command before I test after a shutdown).
The paragraph above was written 2 hours ago.. LOL
After much troubleshooting, and a "re-tune" of the servo drive using the manufacturers procedure, I can now re-define the problem for you.
I turn on the computer and bring up the camsoft interface with full diagnostics showing. I apply Mains power (480V) to the drive and it turns on. (enable circuit is jumpered so it stays on for testing)
The position indicator in the camsoft interface says the motor is moving. The output voltage in the diagnostics panel says 0.0 Volts. The servo motor is hooked up to the drive, drive is enabled, and the drive says its at zero RPM's which is verified by looking at the motor shaft. (its not moving).
Why would the position indicator in the camsoft interface tell me that its moving when clearly it is not and no commands have been issued to make it move.....
Could noise do this??? I do run everything off of a rotary phase converter but the computer, opto22 relays, and all other low voltage stuff is run from the house current.
Any ideas??? Im stumped.
I"ve checked grounds, I've checked resolver phasing, etc etc.
Thank you !!!  |
