How to configure SSE with speed limit activated SBC, SBC before
STO
The configuration of the SSE with speed limit activated SBC, SBC before STO is
identical to the configuration of the same SS1 function with these differences:
• SSE input parameters ( SSE.11 SSE input A and SSE.12 SSE input B ) are used
instead of SS1 input parameters
• SSE output parameters ( SSE.21 SSE output and SSE.22 SSE completed output )
are used instead of SS1 output parameters.
• type of the SSE function must be set: SSE with emergency ramp ( SSE.13 SSE
function = Emergency ramp )
• SAR0 emergency ramp and monitoring limits are used instead of SAR1
parameters (see section Configuring SAR on page 361 ).
• monitoring method is set with parameter ( SSE.14 SSE monitoring method = Time
or Ramp )
• delay for STO activation after SSE request is set with parameter SSE.15 SSE
delay for STO
• delay for activating the brake after the speed limit has been reached is set with
parameter SSE.16 SSE ramp zero speed delay for STO .
Note : If you configure the SSE with speed limit activated SBC function, this activates
the same function in the SS1 function (see section How to configure SS1 with speed
limit activated SBC, SBC before STO on page 347 ). 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 .

SBC function, see page

Related safety functions
The SSE function uses SAR0 ramp parameters. See section Configuring SAR on
page 361 .
The FSO module activates the STO function if the motor speed hits a monitoring limit
(SSE with time or ramp monitoring). See section
Configuring STO on page 331 .
