Adjustment Of Pressure Loop Gain - Mitsubishi Electric MELSERVO MR-J4-B-LL Series Instruction Manual

4. PRESSURE LOOP GAIN ADJUSTMENT

4.5 Adjustment of pressure loop gain

To adjust the pressure control, adjust the following in order of the proportional control gain (pressure loop
gain) and the integral control gain (pressure integral compensation and pressure incomplete integral
coefficient). If the result of the proportional control gain adjustment does not satisfy the required
performance, adjust the integral control gain.
(1) Parameters
The following parameters are used for the gain adjustment of the pressure control.
POINT
Changing [Pr. PT22 Pressure feedback unit constant] also changes the
response performance of the pressure control. In this case, readjust the
pressure loop gain.
