Pr 5.84 sets the threshold at which the invert speed error flag is set. An internal lower limit of 50 % is applied.
When this parameter is set the flux demand is inverted.
When this parameter is set the speed error is inverted.
This parameter is used to apply compensation for IR voltage drop in the field weakening voltage loop such that the EMF within the machine is
regulated rather than terminal voltage. The default value of 100.0 % provides full compensation. This parameter can be adjusted to apply less
compensation if required or not. If this parameter is adjusted then the set point for the field weakening voltage loop (Pr 5.59) may need adjusting also
to get the required armature voltage on the motor.
This parameter is used to apply compensation for IR voltage drop in the machine when the drive is being operated in estimated speed feedback. The
default value of 100 % provides full compensation. In some motors compensation windings are employed to correct for speed droop under load and
so 100 % compensation is not required. In these cases this parameter must be adjusted to apply the correct amount of compensation. Setting a
negative value will cause the speed to fall as load increases.
