242 Configuration
Example 2: The figure below shows an example of the SS1-r function with speed
limit activated SBC set-up:
• SS1 function activated
• SAR1 emergency ramp (always with the SS1 function)
• SS1 with monitored ramp
configure SARn
• automatic acknowledgement
• redundant emergency stop button connected to input
(SS1.11 SS1 input A
• single output connected
• brake connected to redundant output, diagnostic pulses activated
(SBC.21 SBC output
• speed limit activated brake in use, speed limit below which the brake and STO are
activated: 180.0 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 STO after the SBC speed limit has been
reached: 0 ms
• 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 time to zero speed
• 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
