Safe Stop and Safe Stop with Door Monitoring Modes
Chapter 6
Lock Monitoring
If Lock Monitoring is enabled, the Lock Monitoring input (LM_In) must be in
the ON state any time the Door Control output (DC_Out) is in the Lock state,
except for the 5 seconds following the DC_Out output’s transition from the
Unlocked state to the Locked state. If the LM_In input is not ON during this
time, a Lock Monitoring fault occurs. The LM_In input must be OFF when the
DM_In input transitions from ON to OFF (the door opens).
A Lock Monitoring fault is a Stop Category fault, which initiates the configured
Safe Stop Type.

Safety Mode
Safety Mode
Defines the primary operating mode of the speed monitoring safety functions.
Setting:
1 = “Safe Stop”

Safe Stop Input
Safe Stop Input
Configuration for Safe Stop input (SS_In).
“2NC” (1) – Dual-channel equivalent
“2NC 3s” (2) – Dual-channel equivalent 3 s
“1NC+1NO” (3) – Dual-channel complementary
“1NC+1NO 3s” (4) – Dual-channel complementary 3 s
“2 OSSD 3s” (5) – Dual-channel SS equivalent 3 s
“1NC” (6) – Single channel equivalent
Default:
Options:
1 = “2NC”
0 = “Not used”
1 = “2NC”
2 = “2NC 3s”
3 = “1NC+1NO”
4 = “1NC+1NO 3s”
5 = “2 OSSD 3s”
6 = “1NC”

Safe Stop Type
Safe Stop Type
Safe operating stop type selection. This defines the type of Safe Stop that is performed if
the Safe Stop function is initiated by a stop type condition.
“Torque Off” (0) – Safe Torque Off With Standstill Checking
“Torque Off NoCk” (3) – Safe Torque Off Without Standstill Checking
Default:
Options:
0 = “Torque Off”
0 = “Torque Off”
1 = “Safe Stop 1”
2 = “Safe Stop 2”
3 = “Torque Off NoCk”

Stop Mon Delay
Stop Monitoring Delay
Defines the monitoring delay between the request and the Max Stop Time when the
request for a Safe Stop 1 or a Safe Stop 2 is initiated by an SS_In input ON to OFF
transition.
If the Safe Stop Type is Safe Torque Off With or Without Standstill Speed Checking, the
Stop Monitor Delay must be 0 or a Invalid Configuration Fault occurs.
