Safe Limited Speed (SLS) Modes Chapter 7
Safe Limited Speed Reset
A Safe Limited Speed (SLS) Reset is a transition out of actively monitoring safe
limited speed. It can also occur during a [Safe Limited Speed Monitor Delay], if
one is configured. When an SLS Reset occurs, the drive no longer monitors for
safe limited speed and the door is locked. Speed is no longer restricted to the
configured Safe Speed Limit.
The SLS Reset function monitors the SLS_In input. If an SLS Reset is requested,
the drive checks that no faults are present and verifies that the SLS_In input is
ON (closed circuit) before the reset is performed.
When the input is OFF, Safe Limited Speed monitoring takes place, after the
[Safe Limited Speed Monitor Delay], if one is configured. An SLS Reset can be
requested during active Safe Limited Speed monitoring or during a Safe Limited
Speed Monitoring Delay. If a reset is requested during a Safe Limited Speed
Monitoring Delay, the reset does not wait for the delay to time out.
Automatic
Once the SLS_In input is ON (closed), the drive lets the drive resume normal
operating speed. No reset button is required to re-enter the normal run state.
Manual
When the SLS_In input transitions from OFF to ON and the Reset_In input is
ON, an SLS_Reset is attempted.
If the SLS_In transitions from OFF to ON and the Reset_In input is OFF, the
drive stays in its current state, whether it is actively monitoring Safe Limited
Speed or is in a Safe Limited Speed Monitoring Delay, and waits for the Reset_In
input to transition to ON, before attempting the SLS_Reset. If at any time, the
SLS_In input transitions back to OFF, the SLS_Reset is aborted.
Manual Monitored
When the SLS_In input transitions from OFF to ON, the drive waits for an OFF
to ON to OFF transition of the Reset_In input before an SLS_Reset is
attempted. If at any time during this period, the SLS_In input transitions back to
OFF, the SLS_Reset is aborted.
