12 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 usin...

13 Error Codes The SJ200 2 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 Code Name...
