380 Configuration
Example 3: The figure below shows an example of the SLS function with time
monitoring when "Monitoring active and modoff delay time" (parameter SLSx.05) is
selected:
• Basic parametrization of the SLS function made according to chapter Configuring
SLS on page 362.
• Monitoring and modoff delay time are active when drive modulation is lost
(SLSx.05 SLS ramp modoff reaction = Monitoring active and modoff delay time)
• Modoff delay time (SLSx.06 SLS ramp modoff delay time = 300 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.
