factor
Setting range: 100
～
150%
This function enables PWM to work when
the modulation ratio is greater than 1,
which can increase the output voltage of
the drive. Thereby increasing the torque
output and effectively improving the
maximum load capacity of the motor but
the harmonic components of the output
voltage will increase and cause the
temperature of the motor to rise.

frequency
adjustment
0: disable
1: enable
When the automatic adjustment of the
carrier frequency is enabled, the drive will
automatically adjust the carrier frequency
according to the temperature.
