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

Reduce 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!

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".
