Powerup Test

The Powerup Test procedure uses minimal parameter settings to run the motor. The procedure describes two alternative methods for commanding the inverter: via the inverter keypad, or via the logic terminals.

Check power input and motor output wiring (see page 4 diagram).

If using logic terminals for testing, verify correct wiring on [P24], [FW], [H], [O], and [L] (bottom row) per the diagram on page 4.

Reverse [RV] input wiring (defaults to terminal [2]) is optional.
