How to configure SLSn with ramp 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 ramp 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:
• Scaling speed: 1500 rpm (200.202 SAR speed scaling = 1500 rpm)
• Deceleration time and ramp monitoring according to SAR1 parameters
•
ramp time from Scaling speed to zero: 1000 ms (200.112 SAR1 ramp time to
zero = 1000 ms)
•
initial range for monitoring: 100 ms (SARx.02 SAR initial allowed range = 100
ms)
•
minimum allowed ramp time: 500 ms (SARx.21 SAR1 min ramp time to zero =
500 ms)
•
maximum allowed ramp time: 1000 ms (SARx.22 SAR1 max ramp time to
zero = 1500 ms).
• STO.14 time to zero speed with STO and modoff: 2500 ms.
