Does anyone have any [successful] experience with an Allen-Bradley MPL-A320P servo motor and Ultra3000 drive?
We have used the MPL-A320H motor (3500 rpm) in the past without any problems. Now I have an A320P which is rated at 5000 rpm. However, I can't seem to get it to go any faster than 3000 rpm. Normally I would suspect a cable or connection problem, but when the speed is ramped up it faults at almost exactly 3000 rpm every time. I have spent hours tweaking the gains and other settings without any results. This is making me wonder if we got the wrong motor or something. The full P/N is MPL-A320P-HJ22AA. It does have the older 2000-line encoder, but I would assume that when they rate the motor at 5000 rpm, that includes the encoder too.
I would appreciate any suggestions.
