CHAPTER 6 - DETAILED PARAMETER DESCRIPTION
P138 -10.0 to +10.0 %
Slip Compensation [ 0.0 ]
0.1 %
P138 (for values between 0.0 % and +10.0 %) is used in the Motor Slip
Compensation output frequency function, which compensates for the
speed drop as the load increases.
P138 allows the user to set the VSD for more accurate slip compensation.
Once set up P138 will compensate for speed variations due to load by
automatically adjusting both voltage and frequency.

Automatic Torque [ 0.00 ]
Boost 0.01
The automatic Torque Boost compensates for the voltage drop in the
stator resistance as a function of the motor active current.
The criteria for setting P137 are the same as for the parameter P136.
This parame-
ter is shown on the
display(s) onlywhen
P202 = 0, 1 or 2
