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
• If the value is zero (0 rpm) the SBC is not used in the SS1 and SSE with
emergency ramp functions.
• If the value 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
speed limit activated SBC
2. You can also set a negative delay with parameter
• If the value is negative, the FSO activates the SBC at the speed limit (set with
parameter SBC.15 SSE/SS1 SBC
See section
STO on page 280.
• If the value is zero (0 ms) or positive, the FSO activates the SBC and drive
STO functions at the same time when the speed limit is reached.
Note: If parameter

immediate STO functions (see section
function on page 262). In the SS1 (and SSE with emergency ramp) function, this
parameter is relevant always when parameter
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
hit situations, you have to configure the SBC also in the STO function. See section
How to configure the SBC in the STO function
See also section How to fine-tune when SBC speed limits are detected
on page276.
