Configuring Sls; How To Configure Slsn With Time Monitoring - ABB FSO-21 User Manual

Configuring SLS

To configure the SLSn (n = 1...4), set the FSO parameters listed below to appropriate
values using the Drive composer pro PC tool. See parameter groups
page 322 and SLSx
For more information on the SLS function, see page 127.
Depending on the application, set the negative and positive SLS and SLS trip limits
separately.

How to configure SLSn with time monitoring

Example: The figure below shows an example of the SLS1 function with time
monitoring set-up:
• SLS1 function activated
• time monitored deceleration ramp
(SLSx.03 SLS activation monitoring method
• deceleration ramp according to drive parameters (always with time monitoring)
• SLS activation delay: 2000 ms
• automatic acknowledgement
• redundant SLS activation button connected to input
(SLSx.11 SLS1 input A
• single output connected
• positive limits: SLS 1200.0 rpm, trip limit 1320.0 rpm
(200.23 SLS1 limit positive
SLSx.14 SLS1 trip limit positive
• negative limits: SLS -900.0 rpm, trip limit -1020.0 rpm
(200.22 SLS1 limit negative
SLSx.13 SLS1 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
defined by parameter
on page 342.
