How to configure the SBC in the STO function
Use these parameters to configure the SBC:
1. Set the how the brake is used with parameter SBC.11 STO SBC usage:
None: the SBC is not used
Delayed brake (the value can be positive, zero or negative)
Speed limit (possible only when an encoder is used).
2. Set the correct delay with parameter SBC.12 STO SBC delay:
If the value is zero (0ms), the FSO activates the SBC and drive STO functions
at the same time.
It the value is positive, the FSO activates the SBC after the drive STO.
See section How to configure SBC after STO on page 333.
If the value is negative, the FSO activates the SBC before the drive STO.
See section How to configure SBC before STO on page 335.
3. If you use the speed limit activated SBC function, set the correct SBC speed limit
with parameter SBC.14 STO SBC speed.
The drive STO function is activated when the STO request is received and the
SBC when the SBC speed limit is reached. See section How to configure STO
with speed limit activated SBC on page 337).
See also section How to configure mute time for SBC speed limit detection on page
