Chapter 7 Safe Limited Speed (SLS) Modes
Safe Limited Speed Reset
When properly configured for Safe Limited Speed with Door Monitoring, the
safety option must be monitoring motion (SLS_In input is OFF) if the door is
open (DM_In is OFF). Make sure the door is closed before requesting an SLS
Reset.
A Safe Limited Speed Reset results in a Door Monitoring fault if the door is open
(DM_In is OFF) when the reset is requested by a transition of the SLS_In input
from OFF to ON. A Door Monitor fault is a Stop Category fault, which initiates
the configured Safe Stop Type.
