SPEED COMMAND
Slip Comp
Important: Parameters in the Slip Comp Group are used to enable and tune the Slip
Compensation Regulator. In order to allow the regulator to control drive operation, parameter
080 [Speed Mode] must be set to 1 “Slip Comp”.
121 [Slip RPM @ FLA]
Sets the amount of compensation to drive output
at motor FLA. Slip RPM @ FLA = Synchronous
Speed - Motor Nameplate RPM
If the value of parameter 061 [Autotune] = 3
“Calculate” changes made to this parameter will
not be accepted.
Value can be changed by [Autotune] when
“Encoder” is selected in [Feedback Select],
parameter 080.

124 [PI Configuration]
Sets configuration of the PI regulator.
Option Description
AdjVoltTrim (10) Configures the PI regulator output to trim the voltage reference, rather than
the torque or speed references. The trim can be configured to be exclusive by
setting “Excl Mode” (bit 0). Trimming the voltage reference is not compatible
with trimming the torque reference, thus if bits 8 & 10 are set, a type II alarm
will occur, setting “PI Cfg Cflct” (bit 19) in [Drive Alarm 2].
