F40 Carrier frequency (kHz): 004-016
Set this parameter to a level from 4-16kHz as required. (Default is 10kHz).

NOTE: In situations where there is excessive audible noise from the motor or unwanted electrical
noise from the inverter caused by excessive cable length, the carrier frequency can be
adjusted:
To reduce noise due to excessive cable length,
decrease
the carrier frequency.
To reduce motor audible noise,
increase
carrier frequency. However the output current from the
inverter will be de-rated according to the table below.
When the output current is higher than the full load current rating of inverter, the carrier frequency
will be
decreased
automatically.
Current de-rating vs carrier frequency
F41 Auto restart on momentary power loss
000:
Enable
001:
Disable
F41=000: Auto restart after a momentary power loss is enabled. Upon recovery of power with a run
command, as set by parameter F4, the inverter will perform an auto speed search. Once the motor
rotation speed is found, it will accelerate to the reference speed setting.
F41=001: Auto restart disabled.
F42 Auto restart times : 000 - 005
1.) F42=000: The inverter will not auto-restart on a fault trip.
2.) F42>000: The Inverter will carry out an auto speed search 0.5 sec after a fault trip, while the
inverter output is disabled and the motor is coasting to a stop. Once the rotational speed is
determined, the inverter will accelerate or decelerate to its speed reference.
3.) Auto restart is not available for OL1, OL2, OH, and bb faults.
NOTE: Auto restart will not function when DC injection braking or deceleration to stop are
performed.
