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.
3 “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

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
