process:
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!

Reset P23 & P56 to the last setting
Implement the same process for P57 ↓ (lag D
sectionl), P58 ↓ (lag rpm filter) and P151 ↓↑
(monitor speed)!
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".
