Verify AC line voltage at source matches control rating.2. Inspect all power connections for accuracy, workmanship and tightness andcompliance to codes.3. Verify control and motor are grounded to each other and the control isconnected to earth ground.4. Check all signal wiring for accuracy.5. Be certain all brake coils, contactors and relay coils have noise suppression.This should be an R-C filter for AC coils and reverse polarity diodes for DCcoils. MOV type transient suppression is not adequate.WARNING: Make sure that unexpected operation of the motor shaft during startup will not cause injury to personnel or damage to equipment.Check of Motors and Couplings1. Verify freedom of motion for all motor shafts and that all motor couplings aretight without backlash.2. Verify the holding brakes if any, are properly adjusted to fully release and set tothe desired torque value.
