Eliminated from:
9400 HighLine SW V08.00.24.00
Behaviour of the new version?
The drive is able to stop now without reversing motion even if greater S-ramp times are selected.
<hr>
Which products are affected?
9400 HighLine SW ≤ V07.01.06.00
What happens?
Overshoots in negative direction occur when stopping.
When does the problem occur?
The behaviour occurs if larger S-ramp times of e. g. 1 second are set in C02611/0. The Lenze default value for code C02611/0 is 0.100 seconds.
Possible diagnostics?
The value set in code C02611/0 is considerably greater than the Lenze default value of 0.100 seconds, which results in slight overshoots in negative direction when stopping.
Short-term measures/recommendations?
Adjust the S-ramp time in code C02611/0 accordingly to avoid overshoots when stopping.
Evaluation
Very large S-ramp times are rarely used in practice. In most cases, the S-ramp time can be reduced to avoid overshoots.
