How to configure SS1 with speed limit activated SBC, SBC before
STO
Note : If you configure the SS1 with speed limit activated SBC, SBC before STO
function, this activates the same function in the SSE function (see section How to
configure SSE with speed limit activated SBC on page 356 ). This does not activate
the SBC in the STO function. If necessary, configure the SBC also in the STO
function (see section
Configuring STO on page 331 ). See also the note on page 49 .
Example 1: The figure below shows an example of the SS1-t function with speed
limit activated SBC, SBC before STO set-up:
• SS1 function activated ( SS1.01 SS1 activity and version = Version 1 )
• SS1 with time monitored ramp ( SS1.13 SS1 type = SS1-t )
• SAR1 emergency ramp ( 200.112 SAR1 ramp time to zero , always with the SS1
function - see section Configuring SAR on page 361 )
• delay for STO activation after SS1 request: 2000 ms
( SS1.14 SS1-t delay for STO = 2000 ms )
• automatic acknowledgement ( STO.02 STO acknowledgement = Automatic )
• redundant emergency stop button connected to input
( SS1.11 SS1 input A = DI X113:1 & X114:1 )
• single output connected ( SS1.21 SS1 output = DO X114:9 )
• brake connected to redundant output, diagnostic pulses activated
( SBC.21 SBC output = DO X113:7 & X114:7 , SAFEIO.53 and SAFEIO.56 = On ),
SAFEIO.21 Safety relay 1 output = DO X113:7 & X114:7)
• speed limit activated brake in use, speed below which the brake and STO are
activated: 180.0 rpm ( SBC.15 SSE/SS1 SBC speed = 180 rpm )
• delay for activating STO after brake: -300 ms (only a negative delay is possible,
the SBC is activated before STO) ( SBC.12 STO SBC delay = -300 ms )
