Problem:
P share too small
Solution:
→ Rotate K
against F (fine adjustment)
p
soll
→ P gain >
Problem:
P share too large
Solution:
→ Rotate K
against 0 (fine adjustment)
p
soll
→ use DIL 14–16 to reduce the P gain according to the table
Problem:
P share correct
Control deviation too large
ist
Solution:
→ Increase the I gain share

DIL 11 ON = I share = 0
DIL 12 ON = I share connected
→ Rotate K
against F

Problem:
Time constant of the I share too low
Solution:
→ Rotate K
against F until control deviation and vibration are perfect

→ If K
= F is not sufficient, the P share must also be reduced

Problem:
D share too low
Solution:
