Chapter 7 Safe Limited Speed (SLS) Modes
If Safe Limited Speed Monitoring is active (SLS_In input is OFF) and the drive
has verified a safe speed condition, the door can be unlocked and opened.
You can monitor the door’s status with or without the door control (lock/
unlock) function. When door control logic is set to lock, it prevents personnel
from entering the hazardous area when the machine is not at a safe speed or at
Standstill Speed.
Safe Limited Speed Reset
When properly configured for Safe Limited Speed with Door Monitoring, the
drive 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 that initiates
the configured Stop Category.
ATTENTION: Make sure that an open door does not result in a
hazardous situation.
If a Stop Category is initiated or a fault occurs while the drive is actively
monitoring Safe Limited Speed, door control remains unlocked. The safe
state of the SLS_In input can result in the door being unlocked.
