VFD Maintenance Procedure

Periodic Inspection of VFD

Check the following items during periodic maintenance:

  •  The motor should not be vibrating or making unusual noises.
  •  There should be no abnormal heat generation from the Drive or motor.
  •  The ambient temperature should be within the Drive specification

(-10°C to 40°C (14°F to 104°F)).

• The output current value shown in parameter U1-03 should not be higher than the

motor rated current for an extended period of time.

• The cooling fan in the Drive should be operating normally.

Always turn OFF the input power before beginning inspection. Confirm that the digital
operator indicators on the front cover have all turned OFF, and then wait an additional five
minutes before beginning the inspection. Be sure not to touch terminals immediately after the
power has been turned off. Doing so can result in electric shock.

WARNING:

Prior to removing any protective cover or wiring any part of the Drive, remove all

power sources, including main input power and control circuit power. Wait a minimum of 5
minutes after power removal, before removing any cover. The charge lamp located within the
Drive should be off prior to working inside. Even if the charge lamp is off, one must measure
the AC input, output, and DC Bus potential to insure safe levels prior to resuming work. Failure
to adhere to this warning may result in personal injury or death.

Clean off any dirt and dust with an air

gun using clean and dry air at a pressure

between 55-85 psi. Replace the boards if

they cannot be made clean.
