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.

Error Codes The SJ2002 series inverters will trip on over-current, over-voltage, and under-voltage to protect the inverter. The motor output turns OFF, allow- ing the motor to free-run to a stop. Press the Stop/Reset key to reset the inverter and clear the error. Basic Error Codes Error Name Probable Cause(s) Code Over current event while at � Inverter output was short-circuited E01 constant speed � Motor shaft is locked � Load is too heavy Over current event during � A dual-voltage motor is
