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
configure SSE with speed limit activated SBC
the SBC in the STO function. If necessary, configure the SBC also in the STO
function (see section
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 with time monitored ramp
• SAR1 emergency ramp (always with the SS1 function)
• security delay for activating the drive STO: 2000 ms
(SS1.14 SS1-t delay for STO
• 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

• speed limit activated brake in use, speed below which the brake and STO are
activated: 180.0 rpm
• delay for activating STO after brake: -300 ms (only a negative delay is possible,
the SBC is activated before STO)
Note: The same SBC delay is used in the STO and SS1/SSE functions.
• delay for activating the brake after the SBC speed limit has been reached: 0 ms
(SS1.15 SS1-r ramp zero speed delay for STO
• when an encoder is used: zero speed limit to define the safety function as
completed: 90 rpm
(FSOGEN.52 Zero speed with encoder
• when an encoder is not used: delay to define the safety function as completed,
that is, estimated time in which the motor brakes to a stop from the maximum
speed: 1200 ms
• 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
