362 Configuration
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 Safety on
page 402 and SLSx on page 422.
For more information on the SLS function, see page 140.
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 (200.21 SLS1 activity and version = Version 1)
• time monitored deceleration ramp
(SLSx.03 SLS activation monitoring method = Time)
• deceleration ramp according to drive parameters (always with time monitoring)
• SLS activation delay: 2000 ms (SLSx.04 SLS time delay = 2000 ms)
• automatic acknowledgement (SLSx.02 SLS acknowledgement = Automatic)
• redundant SLS activation button connected to input
(SLSx.11 SLS1 input A = DI X113:2 & X114:2)
• single output connected (SLSx.15 SLS1 output A = DO X114:7)
• positive limits: SLS 1200.0 rpm, trip limit 1320.0 rpm
(200.23 SLS1 limit positive = 1200 rpm,
SLSx.14 SLS1 trip limit positive = 1320 rpm).
• negative limits: SLS -900.0 rpm, trip limit -1020.0 rpm
(200.22 SLS1 limit negative = -900 rpm,
SLSx.13 SLS1 trip limit negative = -1020 rpm).
• See also section Configuring mute times on page 393.
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 SMS trip limit positive and above the speed
defined by parameter SMS trip limit negative, respectively.
