Solution:

→ Rotate KP against 13 (fine adjustment)

→ P gain >

Problem:

P share too large

Solution:

→ Rotate KP against 0 (fine adjustment)

➝ Use DIL 14–16 to reduce the P gain according to the table

Problem:

P share correct, control deviation too large

Solution:

➝ Increase the I gain share

→ DIL 11 ON = I share = 0

       DIL 12 ON = I share connected

→ Rotate KI against 13

Problem:

Time constant of the I share too low

Solution:

➝ Rotate KI against 13 until control deviation and vibration are perfect

→ If KI = 13 is not sufficient, the P share must also be reduced
