c |
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 |
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 |
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 > |
