272 Configuration
following parametrization is relevant for a situation where drive modulation is lost
during SLS deceleration ramp and SLS function is activated when motor speed is
higher than SLS limit speed.
For more information on the modoff reaction related to SLS function, see
reaction when modulation is lost during deceleration ramp, with ramp monitoring

How to configure SLSn with time monitoring if drive modulation is
lost during SLS deceleration ramp
Example 1
: The figure below shows an example of the modoff situation with SLS
function with time monitoring when "Modoff delay time" (parameter SLSx.05) is
selected:
• Basic parametrization of the SLS function made according to chapter
.
• Modoff delay time monitoring is active when drive modulation is lost (SLSx.05
SLS ramp modoff reaction = Modoff delay time)
• Modoff delay time (SLSx.06 SLS ramp modoff delay time = 200 ms)
Relevant parameters for this configuration:
• Deceleration time (drive parameter 23.13 Deceleration time 1)
• SLS activation delay: 2000 ms (SLSx.04 SLS time delay = 2000 ms)
• STO.14 time to zero speed with STO and modoff: 2500 ms.
