(2) Adjusting PID contant 

Refer to page, the block diagram of PID control selection, using the following 
procedure to activate PID control and then adjust it while monitoring the 
response. 

( 

I

 )  Enable PID control function (Setting Sn-19 = 09, and if any constant 

Sn-15 ~ 18 setting value is 66, then none of control terminal

can be closed). 

( 

II

 ) Increase the proportional gain P (Bn-14) as far as possible without 

creating oscillation. 

( 

III

 ) Reduce in integral time I (Bn-15) as far as possible without creating 

oscillation. 

( 

IV

 ) Increase the differential time D (Bn-16) as far as possible without 

creating oscillation. 
First set the individual PID control constants, and then make fine 
adjustments. 

 

Reducing Overshooting 

If overshooting occurs, shorten the derivative time D (Bn-16) and lengthen 
the integral time I (Bn-15) 

 
 
 
 
 
 
 
 

 

Rapidly Stabilizing Control Status 

To rapidly stabilize the control conditions even when overshooting occurs, 
shorten the integral time I (Bn-15) and lengthen the derivative time D (Bn-16)
