How to configure Variable SLS with ramp monitoring
Example: The figure below shows an example of the Variable SLS function with ramp
monitoring set-up:
• Variable SLS function activated
(200.61 SLS variable activity and version = Version 1)
• automatic acknowledgement (SLSx.02 SLS acknowledgement = Automatic)
• monitored deceleration ramp
(SLSx.03 SLS activation monitoring method = Ramp)
• deceleration ramp and ramp monitoring limits according to SAR1 parameters,
acceleration ramp according to drive parameters
• single output connected (SLSx.51 Variable SLS output = DO X114:7)
• positive limits: SLS 1200.0 rpm, trip limit 1320.0 rpm
(200.53 SLS4 limit positive = 1200 rpm,
SLSx.43 SLS4 trip limit positive = 1320 rpm).
• negative limits: SLS -100.0 rpm, trip limit: -150.0 rpm
(FSOGEN.51 Zero speed without encoder or when an encoder is used:
FSOGEN.52 Zero speed with encoder), not shown in the figure)
(200.52 SLS4 limit negative = -100 rpm,
SLSx.42 SLS4 trip limit negative = -150 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.
