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, allowing the motor to free-run to a stop. Press the Stop/Reset key to reset the inverter and clear the error.
Error Code Name Probable Cause(s) E35 Thermistor • Thermistor input, [THM] and [L], is over the temp. threshold E60 Communications error • The inverter’s watchdog timer for the communications network has timed out. --- Under-voltage (brownout) with output shutoff • Low input voltage caused the inverter to turn OFF the motor output and try to restart. If unsuccessful, a trip occurs.
