User-defined settings

Modify P56 ↓↑ (D section rpm controller)

Increase P23

Travel slowly over the positioning range

⇒stable, quiet travelling

⇒unstable, unquiet travelling

(no longer corresponds to to the requirements)

Reset P23 & P56 to the last setting

Implement the same process for P57 ↓ (lag D sectionl), P58 ↓ (lag rpm filter) and P151 ↓↑ (monitor speed)!

User-defined settings with variant 3

(P59= 8)

Modify P56 ↓↑ (D section rpm controller)

Increase P23

Travel slowly over the positioning range

⇒stable, quiet travelling

⇒unstable, unquiet travelling

(no longer corresponds to to the requirements)

Reset P23 & P56 to the last setting

Implement the same process for P57 ↓ (lag D

section), P58 ↓ and (lag rpm filter)!

Optimizing the movement cycle

Optimise pre-control parameters P25 ↓↑ (rpm pre-control), P26 ↓ (acceleration pre-control), P69

↓(current pre-control) and P70 ↓ (return pre- control).

Check current restriction:

During acceleration/braking, the current limit should not be reached or only briefly.

The optimizing display (P233/234=13 and 14) shows the time in which the controller is operating at the current limit.

Use the pre-control parameters or increase ACCEL to reduce the "time at current limit".

Note

♦The arrows behind the parameters show the preferred direction for the parameter optimization.

↓Reduce parameter ↑ Increase parameter

↓↑ Both directions could lead to a better setting.

The optmizing direction shown usually leads to a good control result in our experience: however, this cannot apply to every application case!
