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 8 diagram).
If using logic terminals for testing, verify correct wiring on [PCS],
[FW], [H], [O], and [L] (bottom row) per the diagram on page 8.
Reverse [RV] input wiring (defaults to terminal [2]) is optional.
