Installation Checklist
Wiring (Amplifier/PCM Module)
______a. Ensure proper wire size used for application.
______b. Ensure resolver cable is connected securely at both ends.
______c. Wiring should be neat and orderly.
______d. Wiring should be properly labeled.
______e. Check electrically, Ohm out before power-up.
______f. Is AC wiring through a transformer? If so, is the wiring and the transformer
large enough for worst case current draw for the application?
______g. High voltage wiring should be routed in conduit. Low voltage signal wires
should be separated from high voltage wires. If low and high voltage wires
must cross, they should cross at 90° angles.
______h. Is system properly grounded? Single point ground for chassis, power
supplies, etc.
Motor/Gear Reducer
______a. Check coupling to motor shaft. Must be flexible and properly aligned.
______b. Check oil type in indexers and worm gear speed reducers. (Heavy oil may
produce enough frictional torque to prevent the system from reaching
desired performance until this oil reaches operating temperature).
______c. Check maximum rated input speed to gear reducers and indexers.
Maximum input speed = ______ RPM. Motor speed capability is usually
much greater than that of a typical reducer.
______d. Does motor run smoothly over desired speed range?
______e. Check load for mechanical restriction (rubbing, binding, or jerky
movement).
