When "100 or 101" is set, turning on the RT
signal set the electronic thermal relay
function to the thermal characteristic for the
constant-torque motor.
You can change the PWM carrier
frequency. Increasing this value reduces
the motor audible noise, but increases
noise and leakage current.
The setting is in [kHz].

Valid for eliminating noise of the frequency
setting circuit.
A larger set value increases the time

You can control the operation of the cooling
fan built in the inverter. (Operates in power-
on status.)
0: The fan normally operates at power on
of the inverter.
1: The fan is normally on during inverter
operation. The fan switches on/off
according to the temperature during a
stop of the inverter whose status is
monitored.
