4-6 Diagnostics, Troubleshooting, and Start-Up Guidelines
4.7.3 Physically Inspecting the Drive
Before operating the equipment, DISCONNECT AND LOCK OUT ALL INCOMING AC
LINE/DC BUS POWER AND CONTROL POWER TO THE DRIVE and perform the
following steps:
Step 1. Carefully inspect the Power Module and other drive components for physical
damage. Verify free operation of all switch relays, auxiliary contacts, and
contactors.
Step 2. Visually inspect internal buses and wiring for loose or broken connections or
damaged wires.
Step 3. Visually check for damaged components.
Step 4. Check fuses.
Step 5. Verify that all shutdown interlocks around the machine are operational.
4.7.4 Physically Inspecting the Motor
Carefully read and understand the instruction manual that describes your AC motor.
Then make the following motor inspection:
Step 1. Disconnect and lockout all incoming line power and control power to the
drive.
Step 2. Check that the motor is installed according to the motor instruction manual.
Step 3. If possible, uncouple the motor from the driven machinery.
Step 4. Rotate the motor shaft by hand to check that the motor is free from any
binding or mechanical load problem.
Step 5. Check that no loose items such as shaft keys, couplings, etc., are present.
Step 6. Check all connections for tightness and proper insulation.
Step 7. Check that the interior of the motor is clean and dry.
4.7.5 Checking the Installation with Power Off
Perform the following tests to verify that:
• Correct power is being supplied to the drive
• Wiring has been done properly
• There are no grounds in the magnetic control circuits or rotating equipment
• All safety devices are in place and functional.
!
ATTENTION:Before starting the motor, remove all unused shaft keys
and loose rotating parts to prevent them from flying off. Replace all covers
and protective devices. Failure to observe these precautions could result
in damage to equipment and bodily injury.
