Optimizing acceleration
If the maximum acceleration of the servo loop cannot be determined with the battery supply, the
acceleration can be optimized as follows:
No
Yes
Enter following values for
position supervision
MP1410: 0.5
MP1420: 30
MP1060
Increase "acceleration"
in small steps.
Press machine START button in the
