Keep in mind that after changes in the P-band, the process can take a very long time 
to become consistent again, especially with sluggish processes. Manual adjustment 
can take from a few minutes to several hours. 
 
In the flowchart, PBu is the 

ultimate P-band

, Tu is the 

ultimate period

 

If both values are equal, we speak of the critical-stable state (see picture). 
 
 

 

Critical steady state

 

 
If the control result after manual adjustment according to the flow chart still does not 
provide a satisfactory result, the following rules can be applied: 
 

Setting sequence 

Symptom 

Solution 

1.  proportional band (P) 

PB1 and/or PB2 

Slow response 

Reduce PB1 or PB2 

High oversteer or  

oscillation 

Increase from PB1 or 

PB2 

2.  integral time (I) 

TI1 and/or TI2 

Slow response 

Reduce TI1 or TI2 

Unstable or oscillating 

Increase from TI1 or TI2 

3.  difference time (D) 

TD1 and/or TD2 

Slow response or  

oscillation 

Reduce TD1 or TD2 

High oversteer 

Increase from TD1 or 

TD2
