indicator is off.
1: Runs at the opposite direction, the inverter
runs in the reverse direction. FWD/REV
indicator is on.
Modify the function code to shift the rotation
direction of the motor. This effect equals to the
shifting the rotation direction by adjusting
either two of the motor lines (U, V and W). The
motor rotation direction can be changed by
QUICK/JOG on the keypad. Refer to parameter
P07.02.
Note: When the function parameter comes
back to the 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.
The advantage of high carrier frequency: ideal
current waveform, little current harmonic wave
and motor noise.
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.
