I have been sorting out the wiring and all axes work, I am getting motion errors on the x or table axis, mostly, some on the others. It is my guess it weighs about 350#. I have been able to reduce that some with the acceleration rate, currently set at 150mm/sec/sec. Even in jog mode when stopping the move it stops abruptly and and gives me a flashing red, motion error. I am running fanuc model 5 motors, 110 v 5.9nm 6.8 amp peak. I have a 1.5kw power supply, powering 3 motors and 1 extra axis driver card, have to put a new encoder on the 4th axis motor. I hooked up the regenerative resistor from the original controller, 15ohm that helped some, should I perhaps increase the setting for over voltage fault? if it was an encoder, I would be more inclined to think it would not be intermittent at all. also it would not be all three of the operating axes. Is it possible I need more power?
Thanks.
