Control system functions (Pr. 818 to Pr. 837)
3.32.5 Speed detection filter function (Pr. 823, Pr. 833
)
3.32.6 Current loop proportional gain setting for vector control
(Pr. 824, Pr. 834
)
3.32.7 Current control integral time setting for vector control
(Pr. 825, Pr. 835
)
3.32.8 Torque setting filter function (Pr. 826, Pr. 836
)
z Set the time constant of the primary delay filter relative to the speed feedback signal.
Since this function reduces the speed loop response, use it with the factory setting.
Set the time constant when speed ripples occur due to harmonic disturbance.
Note that a too large value will run the motor unstably.

REMARKS
When speed ripples are large, setting this parameter Pr. 823 or Pr. 833 ensures stability.
z Set the current loop proportional gain for vector control.
Increasing the gain enhances the torque response level, but a too large gain will cause instability,
generating harmonic torque pulsation.
