Hi Kurt,
Welcome !--
It could be as Alan said above, or it also could be that the motor has seized, in the "non home" position, which will cause the MCC to attempt to "home" it, upon start-up.
This can be checked by looking at the gripper position, which should be over the discs, and the switch located at the bottom of the motor--one of the two switches (Don't re-call which one) should be "activated" by that white cam.
You also should be able to turn the white cam CW, with your hand, without any "pressure". If you find it's not homed, and/or you can't turn it, I would assume it, or the gripper has seized. I have seen many motors seize, due to lack of proper oil.
I have spoken with the people that make that motor, and they recommend, despite the fact that Rowe claims it needs "no lubrication", that the two large oil wicks on the armature shaft be filled with SAE 20 wt. ND oil.
HTH,
Ron Rich
