How to configure SLSn with ramp monitoring

Example: The figure below shows an example of the SLS2 function with ramp
monitoring set-up:
• SLS2 function activated
• monitored deceleration ramp
(SLSx.03 SLS activation monitoring method
• deceleration ramp and monitoring limits according SAR1 parameters (see section
Configuring SAR
• automatic acknowledgement
• redundant SLS activation button connected to input
(SLSx.21 SLS2 input
• single output connected
• positive limits: SLS 1200.0 rpm, trip limit 1320.0 rpm
(200.33 SLS2 limit positive
SLSx.23 SLS2 trip limit positive
• negative limits: SLS -900.0 rpm, trip limit -1020.0 rpm
(200.32 SLS2 limit negative
SLSx.22 SLS2 trip limit negative
• See also section
Note: The difference between the SLS limit and the corresponding SLS trip limit must
be at least 0.1 rpm.
Note: If you also use the SMS function, the SLS trip limits positive and negative must
be below the speed defined by parameter
