4. PRESSURE LOOP GAIN ADJUSTMENT 

4 -  4 

 
4.5 Adjustment of pressure loop gain 
 

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. 

 
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. 

 

Parameter Symbol 

Name 

PT01 

APA 

Pressure loop gain 

PT02 

AIA 

Pressure integral compensation 

PT03
