Powerup Test - Hitachi SJ100 Series Quick Reference Manual

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.
