P04.01
Torque boost
close
features of low frequency torque. P04.00 is for
the max. output voltage V
b
.
P04.01 defines the percentage of closing
frequency of manual torque to f
b
.
Torque boost should be selected according to
the load. The bigger the load is, the bigger the
boost is. Too big torque boost is inappropriate
because the motor will run with over-magnetic,
and the current of the inverter will increase to
raise the temperature of the inverter and
decrease the efficiency.
When the torque boost is set to 0.0%, the
inverter is automatic torque boost.
Torque boost threshold: under the threshold, the
torque boost is valid, but over the threshold, the
torque boost is invalid.

Motor V/F slip
compensation
gain
This function code is used to compensate the
change of the rotation speed caused by load
during compensation SVPWM control to
improve the rigidity of the motor. It can be set to
the rated slip frequency of the motor which is
counted as below:
△
f=f
b
-n*p/60
Of which, f
b
is the rated frequency of the motor,
its function code is P02.02 ; n is the rated rotating
100.0%
