P08.09
V/Fcompensation maximum frequency(HZ)
0.0～100.0（10.0）
P08.09 set to provide maximum frequency of compensation torque under V/F control
effect of torque compensation function : incease output voltage when converter run
under low-frequency,V/F control mode to offset stator’s voltage to generate enough torque, so
that motor can run normally.
Note: increase range of torque should be set properly based on load’s situation, if increase

excessively , it will generate larger current impact during start process.

Function Parameter List
P08.11
Carrier wave frequency(KHz)
2.0～10.0(4.0)
No carrier wave inspection delay(ms)
0.0～2000(500)
carrier wave frequency adjustment:increase carrier wave’s frequency to make sound
become lighter when variable frequency motor’s sound is excessively large, but increasing
carrier wave’s frequency will also increase converter’s loss.
P08.12
Restrain oscilation upper limit（%）
0～10.0(0)
P08.13
estrain oscilation lower limit（%）
0～10.0(0)
if motor produce oscillation when rise or fall , increase the upper limit of
Restricted oscillation under drive status, increase the lowerlimit of
Restricted oscillation under brake status .
