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.
Values
Default
2.0 Hz
Min/Max:
0.0/ 10.0 Hz
Display:
0.1 Hz
A438 [Process Time Lo]
Related Parameter(s):
d010, P104
Scales the time value when the drive is running at
P104
[Minimum Freq]. When set to a value other than zero,
d010
[Process Display] indicates
the duration of the process.
Values
Default
0.00
Min/Max:

A439 [Process Time Hi]
Related Parameter(s):
d010, P105
Scales the time value when the drive is running at
P105
[Maximum Freq]. When set to a value other than zero,
d010
[Process Display]
indicates the duration of the process.
Values
Default
