Configuration 345
Example 2: The figure below shows an example of the SS1-r function with speed
limit activated SBC set-up:
• SS1 function activated (SS1.01
SS1 activity and version = Version 1)
• SAR1 emergency ramp (200.112 SAR1 ramp time to zero, always with the SS1
function - see section Configuring SAR on page 361)
• SS1 with monitored ramp (SS1.13 SS1 type = SS1-r). See also section How to
configure SARn on page 361.
• 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 limit 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 is zero (STO and SBC are activated at the
same time) (SBC.12 STO SBC delay = 0ms)
• delay for activating the brake and STO after the SBC speed limit has been
reached: 0 ms (SS1.15 SS1-r ramp zero speed delay for STO = 0ms)
• when no encoder is in use: delay for defining the safety function as completed,
that is, an estimated time in which the motor brakes to a stop from the maximum
speed: 1200 ms (SBC.13 SBC time to zero speed = 1200 ms)
• 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).
