This parameter can compensate for the changes of motor speed due to the load is
applied during V/F control, so as to improve the mechanical properties of the motor
hardness. This value should be set to the rated slip frequency of motor, the rated slip
frequency is calculated as follows:
Rated slip frequency = FB-n * p/60
Where: FB is for the motor rated frequency, its corresponding function code is b0.04, n
is the motor rated speed, its corresponding function code b0.05, P is the number of
motor pole pairs.
5-2-7.F5 Group - Vector control group
F5 function code is only valid to vector control, invalid to V/F control

The above parameters apply only to the vector control mode. Below switching
frequency 1 (F5.02), speed loop PI parameters: F5.00 and F5.01. Above switching
frequency 2 (F5.05), speed loop PI parameters: F5.03 and F5.04. Between the two, PI
parameters are obtained by the linear changes of two sets of parameters, as shown
below:
