By means of a current monitor at the drive amplifier you may find out whether
the current limit is reached during the process of acceleration or braking. In the
affirmative, the time programmed is too short.
Another possibility to find out whether the values are too small is observing the
contouring distance Delta_s: major fluctuations during accelerating or braking
indicate that the appropriate values are too small.
Times being too long are uncritical for the control but do, however, negatively
influence the duration of positioning. The Controller limits the values to a
maximum size, which, however, can only be attained under most unfavourable
conditions (see storage location 3/35 in appendix A).
✔
Check by manually displacing the drive into both directions at low speed
(">" and "<") in accordance with the information supplied above, whether
the times are too short or whether they could be reduced (higher mechani-
cal load!).
✔
If necessary, program other values (storage locations 3/35...38) and check
again the drive behaviour with these new values.
