How to configure the SBC in the SS1 function
Use these parameters to configure the SBC:
1. Set the correct SBC speed limit with parameter SBC.15 SSE/SS1 SBC speed:
• If the value is zero (0rpm) the SBC is not used in the SS1 and SSE with
emergency ramp functions.
• If the value is positive (the corresponding negative value is used in the
opposite direction), the FSO activates the SBC and drive STO functions at the
same time when the speed limit is reached. See section How to configure SS1
with speed limit activated SBC on page343.
2. You can also set a negative delay with parameter SBC.12 STO SBC delay:
• If the value is negative, the FSO activates the SBC at the speed limit (set with
parameter SBC.15 SSE/SS1 SBC speed) and the drive STO after this delay.
See section How to configure SS1 with speed limit activated SBC, SBC before
STO on page 347.
• If the value is zero (0ms) or positive, the FSO activates the SBC and drive
STO functions at the same time when the speed limit is reached.
Note: If parameter SBC.11 STO SBC usage is Delayed brake, the same
parameter SBC.12 STO SBC delay is used also in the STO and SSE with
immediate STO functions (see section How to configure the SBC in the STO
function on page 329). In the SS1 (and SSE with emergency ramp) function, this
parameter is relevant always when parameter SBC.15 SSE/SS1 SBC speed is
not zero.
Monitoring limit hits in the SS1 function
When you configure the SBC in the SS1 (and SSE with emergency ramp) function,
this does not take the SBC into use in the STO function. Therefore, the SBC is not
activated in limit hit situations if parameter SBC.11 STO SBC usage is None. For limit
hit situations, you have to configure the SBC also in the STO function. See section
How to configure the SBC in the STO function on page 329.

398.
