If the auto restart number is set, be careful when the inverter resets from a fault trip. The
motor may automatically start to rotate.
•
In HAND mode, auto restart resets the trip condition but it does not restart the inverter
operation.
•
In AUTO mode,
-
if the auto restart is configured, the inverter restarts after a trip condition is released
(command via digital input is used to restart the operation).
-
if the auto restart is not configured and the trip condition is released using the OFF
key, or the switches at the terminal input, the inverter stays in the OFF state.
Because the command information is reset along with the trip condition, a new
command is required to operate the inverter.

Description
CON-04
Carrier Freq
Adjusts motor operational noise by changing carrier frequency settings.
Power transistors (IGBT) in the inverter generate and supply high
frequency switching voltage to the motor. The switching speed in this
process refers to the carrier frequency. If the carrier frequency is set high, it
reduces operational noise from the motor. If the carrier frequency is set low,
it increases operational noise from the motor.
CON-05 PWM
Mode
The heat loss and leakage current from the inverter can be reduced by
changing the load rate option at CON-
05 (PWM Mode). Selecting ‗1
(LowLeakage P
WM)‘ reduces heat loss and leakage current, compared to
when ‗0 (Normal PWM)‘ is selected. However, it increases the motor noise.
