To start with set the parameters per the motor data plate values. Amps, Volts, Hertz. Get the motor running from the inverter keypad. Once that is done and the spindle is running OK, then is time to get it talking to the MultiCam controller. That should be accomplished by setting the correct parameters in the inverter.
