1.3 Before Operation
Warning
Make sure the inverter capacity matches the parameters 13-00.
Reduce the carrier frequency (parameter 11-01) If the cable from the inverter to the
motor is greater than 80 ft (25m). A high-frequency current can be generated by stray
capacitance between the cables and result in an overcurrent trip of the inverter, an
increase in leakage current, or an inaccurate current readout.
Be sure to install all covers before turning on power. Do not remove any of the covers while
power to the inverter is on, otherwise electric shock may occur.
Do not operate switches with wet hands, otherwise electric shock may result.
Do not touch inverter terminals when energized even if inverter has stopped, otherwise
electric shock may result.
1.4 Parameters Setting
Caution
Do not connect a load to the motor while performing a rotational auto-tune.
Make sure the motor can freely run and there is sufficient space around the motor when
performing a rotational auto-tune.
