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
instead of SS1 input parameters
• SSE output parameters
are used instead of SS1 output parameters.
• type of the SSE function must be set: SSE with emergency ramp
function = Emergency ramp)
• SAR0 emergency ramp and monitoring limits are used instead of SAR1
parameters (see section
• monitoring method is set with parameter
or Ramp)
• security delay for activating the drive STO is set with parameter
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
Note: If you configure the SSE with speed limit activated SBC function, this activates
the same function in the SS1 function (see section
limit activated SBC, SBC before STO
in the STO function. If necessary, configure the SBC also in the STO function (see
section Configuring STO

The SSE function uses SAR0 ramp parameters. See section
page 294.
The FSO module activates the STO function if the motor speed hits a monitoring limit
(SSE with time or ramp monitoring). See section
