358 Configuration
Example 2: The figure below shows an example of the SSE with emergency ramp
function with speed limit activated SBC set-up with ramp monitoring:
• SSE with emergency ramp (SSE.13 SSE function = Emergency ramp)
• SAR0 emergency ramp (200.102 SAR0 ramp time to zero, always with the SSE
function - see section Configuring SAR on page 361)
• SAR0 monitored ramp (SSE.14 SSE monitoring method = Ramp, see also
section Configuring SAR on page 361)
• redundant emergency stop button connected to input
(SSE.11 SSE input A = DI X113:1 & X114:1)
• single output connected (SSE.21 SSE output = DO X113:9)
• 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 240.0 rpm (SBC.15 SSE/SS1 SBC speed = 240 rpm)
• delay for activating STO after brake is zero (STO and SBC are activated at the
same time) (SBC.12 STO SBC delay = 0ms)
• 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 = 0ms)
• STO is activated if brake feedback fails (SBC.22 SBC feedback action = STO)
• brake feedback input connected to input
(SAFEIO.22 Safety relay 1 feedback
= DI X113:2)
• feedback input type NC (inverted state compared with the brake relay)
(SAFEIO.23 Safety relay 1 feedback type = Mechanically linked NC contacts).
