A436 [Compensation]
Enables/disables correction options that may improve problems with motor instability.
Options
0
“Disabled”
1
“Electrical” (Default)
Some drive/motor combinations have inherent instabilities which are exhibited as
non-sinusodial motor currents. This setting attempts to correct this condition.
2
“Mechanical” Some motor/load combinations have mechanical resonances which can be excited by
the drive current regulator. This setting slows down the current regulator response and
attempts to correct this condition.

“Both”
A437 [Slip Hertz @ FLA]
Related Parameter(s): P103
Compensates for the inherent slip in an induction motor. This frequency is added to the commanded output frequency based on motor current.
