If the display shows a fault code, refer to section 7. If the motor does not start up when the ON command has been given, check that the ON command is valid,check if a frequency setpoint has been entered in P005 and check that the motor specifications have beenentered correctly under parameters P080 to P085. If the inverter is configured for operation via the front panel (P007 = 001) and the motor does not start when theRUN button is pressed, check that P121 = 001 (RUN button enabled). If the motor does not run after parameters have been changed accidentally, reset the inverter to the factorydefault parameter values by setting parameter P944 to 1 and then pressing P.
