How to configure SSE with speed limit activated SBC

Note: If you configure the SSE with speed limit activated SBC function, this activates
the same function in the SS1 function (see section
limit activated SBC
function. If necessary, configure the SBC also in the STO function (see section
Configuring STO on page 264). See also the note on page 42.
Example 1: The figure below shows an example of the SSE with emergency ramp
function with speed limit activated SBC set-up with time monitoring:
• SSE with emergency ramp
• SAR0 emergency ramp (always with the SSE function, see also section
Configuring SAR
• time monitored ramp
• security delay for activating the drive STO: 2000 ms
(SSE.15 SSE delay for STO
• redundant emergency stop button connected to input
(SSE.11 SSE input A
• single output connected
• brake connected to redundant output, diagnostic pulses activated
(SBC.21 SBC output
• speed limit activated brake in use, speed below which the brake and STO are
activated 240.0 rpm
• delay for activating STO after brake is zero (STO and SBC are activated at the
same time) (SBC.12 STO SBC delay
• delay for activating the brake and drive STO after the speed limit has been
reached 0 ms (SSE.16 SSE ramp zero speed delay for STO
• STO is activated if brake feedback fails
• brake feedback input connected to input
(SAFEIO.22 Safety relay 1 feedback
• feedback input type NC (inverted state compared with the brake relay)
(SAFEIO.23 Safety relay 1 feedback type
• See also section
on page 276). This does not activate the SBC in the STO
