OVC climbs while the servo has no motion in the RV unit. With the RV unit disconnected from the turntable and servo installed the problem returns. With the servo totally removed everything acts as normal. I would expect to see the current climb when first starting the motion and then settle once motion was established, but not when the servo is at rest! Anyways we took the machine apart to try and diagnose the problem and here is what we found.
When turning the servo the current actually drops, but at rest is when the current increases. Note im using MORGRP.OVCMNTR to watch the current draw on the motor. Whats really strange about this situation is the manner in which the OVC alarm occurs. The motor is a new aif12/4000 motor that is mated to an 80:1 gear reduction rv unit (this turns a large turntable). Im having a problem with an aux axis on a machine we built.
