Safe Limited Speed (SLS) Modes
Chapter 7
Speed Hysteresis
The [Safe Limited Speed Hysteresis] parameter provides hysteresis for the
SLS_Out output when the drive is configured for SLS Status Only and Safe
Limited Speed monitoring is active. The SLS_Out output is turned ON if the
speed is less than the Low Threshold [(Speed Hysteresis/100) x Safe Speed
Limit]. The SLS_Out output is turned OFF when the speed is greater than or
equal to the configured [Safe Speed Limit].
The SLS_Out output remains OFF if Safe Limited Speed monitoring begins
when the detected speed is less than the configured Safe Speed Limit but greater
than or equal to the Low Threshold [(Speed Hysteresis/100) x Safe Speed
Limit].
The SLS_Out output is held in its last state when the speed is less than the
configured Safe Speed Limit and the speed is greater than or equal to the Low
Threshold [(Speed Hysteresis/100) x Safe Speed Limit].
