The following applies from SW ≥ 01.05.10.00:
If SBM is set to "Motor in operation", the SBM relay switches when No-Flow Stop is active.
If SBM is set to "Ready for operation", the SBM relay does not switch when No-Flow Stop is

Setting
SBM trigger delay
SBM reset delay
Table 32: Trigger and reset delay
• Triggering of the SBM signal after changing an operating status is delayed.
• Resetting of the SBM signal after changing the operating status is delayed.
Trigger delays are used so that processes are not influenced by very brief changes in the operating state.
If an operating state change can be reversed before the end of the set time, the change is not reported to the
SBM.
A set SBM trigger delay of 0 seconds reports an operating state change immediately.
When an operating status change occurs only for a short duration, the reset delay prevents a flutter of the
SBM signal.
NOTICE
SBM trigger and SBM reset delay is set to 5 seconds as a factory setting.
