F3-16
Torque boost at
low frequency
factory default
value
100%
setup range
0%～200%
This parameter is used in vector control 1 starting torque boost at low
frequency ,the larger its value, the higher low frequency torque ,but all of this may
cause no-load current too higher. In the case of driving the load , the smaller its
value is , the lower motor temperature rise is at the low frequency .
F3-17
skip compensation
coefficient
factory default
value
100%
setup range
50%
～
200%
For the speed-less sensor vector control, this parameter is used to adjust the
stabilizing speed precision for motor, when the speed is too large, this parameter
needs to be decreased, on the contrary, it needs to be enlarged.
F3-18
Time constant of
speed command
factory default
value
0.000s
setup range
0.000s
～
0.100s
F3-19
Time constant of
speed loop
factory default
value
0.000s
setup range
0.000s
～
0.100s
In the vector control mode, the output of speed loop regulator is a torque current
command. This parameter is used to filter the torque command ,generally, is in no
