Speed Detection Filter Function (Pr. 823, Pr. 833); Current Loop Proportional Gain Setting For Vector Control (Pr. 824, Pr. 834); Current Control Integral Time Setting For Vector Control (Pr. 825, Pr. 835); Torque Setting Filter Function (Pr. 826, Pr. 836) - Mitsubishi Electric FR-V560 Instruction Manual

Control system functions (Pr. 818 to Pr. 837)
4.32.5 Speed detection filter function (Pr. 823, Pr. 833
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.
Parameter
823 Speed detection filter 1 (when RT signal is off)
833 Speed detection filter 2 (when RT signal is on)
REMARKS
When speed ripples are large, setting this parameter Pr. 823 or Pr. 833 ensures stability.
4.32.6 Current loop proportional gain setting for vector control
(Pr. 824, Pr. 834
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.
Pr. 824 "torque control P gain 1" and Pr. 834 "torque control P gain 2" are 0 to 200% in the setting range and
100% in the factory setting.
For general adjustment, set them within the range 50 to 200%.
Parameter
824 Torque control P gain 1 (when RT signal is off)
834 Torque control P gain 2 (when RT signal is on)
REMARKS
The factory setting ensures fully stable operation.
For general adjustment, make setting within the range 50 to 200% as a guideline.
4.32.7 Current control integral time setting for vector control
(Pr. 825, Pr. 835
Set the current loop integral compensation time for vector control.
A small value enhances the torque response level, but a too small value will cause current fluctuation.
Parameter
825 Torque control integral time 1 (when RT signal is off)
835 Torque control integral time 2 (when RT signal is on)
REMARKS
The factory setting ensures fully stable operation.
4.32.8 Torque setting filter function (Pr. 826, Pr. 836
Set the time constant of the primary delay filter relative to the external torque command (analog input
command).
Set a large time constant value when you want to delay the tracking of the torque command, the analog
input voltage fluctuates, etc.
Parameter
826 Torque setting filter 1 (when RT signal is off)
836 Torque setting filter 2 (when RT signal is on)
