Problem:

P share too small

Solution:

→ Rotate Kp against F (fine adjustment)

→ P gain >

c

technical illustration-0811405157-

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

d

technical illustration-0811405157-

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 F

e

technical illustration-0811405157-

Problem:

Time constant of the I share too low

Solution:

→ Rotate Ki against F until control deviation and vibration are perfect

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

f

Problem:

D share too low

Solution:

→ Rotate KD against F

→ D share >
