2.7.7 ELECTRONIC THERMAL OVERLOAD FUNCTION

Item Name
Motor Type
Motor Rated Current
Motor output current is detected by the inverter built-in electrical thermal overload function, and inverter
exclusive use motor or standard motors are prevented from overloading. (It is not necessary to mount the
thermal relay externally. However, to connect several motors to one inverter, a thermal overload relay
must be inserted for each motor. It is necessary to reduce carrier frequency according to the wiring
distance between the inverter and motor when thermal overload relays are inserted. For details, refer to the
precautions on wiring described on page 12)
Pn-19 = Motor rated current value
Set the motor rated current value according to the value on the motor nameplate.
