No. 18
No. 19
Motor output current is monitored by the Inverter's built-in elec-
tronic thermal overload function to prevent Inverter exclusive-use
motors or standard motors from overloading.
It is not necessary to mount an thermal overload 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 in 1-4 Wir-
ing .
No. 19 = Motor rated current value
Set the motor rated current value according to the
value on the motor nameplate.
