Since the inverter is provided with electronic thermal overload pro-
tective function in order to protect the motor from overheating
faults, set the rated current value described on the motor name-
plate. Standard 4-pole motor current value is set as the initial val-
ue.
Note Provide a thermal relay or thermal protector when more than one
motor is operated simultaneously.
