Configuration 383
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
) is
selected:
• Basic parametrization of the SLS function made according to chapter
on page
• Modoff delay time monitoring is active when drive modulation is lost (
• Modoff delay time (
= 200 ms)
Relevant parameters for this configuration:
• Scaling speed: 1500 rpm (
= 1500 rpm)
• Deceleration time and ramp monitoring according to SAR1 parameters
•
ramp time from Scaling speed to zero: 1000 ms (
= 1000 ms)
•
initial range for monitoring: 100 ms (
ms)
•
minimum allowed ramp time: 500 ms (
=
500 ms)
•
maximum allowed ramp time: 1000 ms (
= 1500 ms).
•
Time to zero speed with STO and modoff
: 2500 ms.
