default value, the motor's running direction will come back to
the factory default state, too. In some cases it should be
used with caution after commissioning if the change of
rotation direction is disabled.
2: Forbid to run in reverse direction: It can be used in
some special cases if the reverse running is disabled.

setting
The disadvantage of high carrier frequency: increasing the
switch loss, increasing inverter temperature and the impact
to the output capacity. The inverter needs to derate on high
carrier frequency. At the same time, the leakage and
electrical magnetic interference will increase.
Applying low carrier frequency is contrary to the above, too
low carrier frequency will cause unstable running, torque
decreasing and surge.
SALICRU has set a reasonable carrier frequency when the
inverter is in factory. In general, users do not need to change
the parameter.
When the frequency used exceeds the default carrier
frequency, the inverter needs to derate 10% for each
additional 1kHz carrier frequency.
Setting range:1.0~15.0kHz
