SS Out
This bit is set to 1 if the dual-channel SS_Out output is being commanded to the ON state. This bit is the commanded value, not a readback
value.
This bit is set to 0 if the SS_Out output is being commanded to the OFF state.
9
SLS In
This bit reflects the logical value evaluated for the dual-channel SLS_In input.
10
SLS Req
This bit is set to 1, if the Safe Limited Speed operation has been requested while the safety option is actively monitoring motion or a SLS
Monitoring Delay [LimSpd Mon Delay] is in progress.
11
SLS In Prog
This bit is set to 1 when Safe Limited Speed monitoring is active.
12
SLS Out
This bit is set to 1 if the dual-channel SLS_Out output is being commanded to the ON state. This bit is the commanded value, not a readback
value.
13
SMS In Prog
This bit is set to a 1, if Safe Maximum Speed monitoring is enabled and Safe Maximum Speed is being monitored.
14
SMA In Prog
This bit is set to 1, if Safe Maximum Acceleration monitoring is enabled and safe maximum acceleration is actively being monitored.
15
SDM In Prog
If Safe Direction monitoring is enabled and configured for Positive Always or Negative Always, the SDM_In_Progress bit is set to 1 any time
the safety option is configured for any Safety mode other than Disabled.
If Safe Direction monitoring is enabled and configured for Positive During SLS or Negative During SLS, then this bit is set to 1 if the safety
option is actively monitoring for Safe Limited Speed. It is set to 0 in any other operating mode.
16
DC Lock
This bit is set to 1 if door control logic status is Lock.
This bit is set to 0 if door control logic status is Unlock.
17
DC Out
This bit is set to 1 if the dual-channel DC_Out output is being commanded to the ON state. This is the commanded value, not the readback
value.
This bit is set to 0, if the dual-channel DC_Out output is being commanded to the OFF state.
18
DM In
This bit is set to 1 if the logical value of the dual-channel DM_In input is evaluated as 1.
This bit is set to 0 if the logical value of the dual-channel DM_In input is evaluated as 0.
19
DM In Prog
The status of this bit is dependent on the safety option’s speed monitoring configuration. The bit is 1 when:
• the safety option is configured for Safe Stop with Door Monitoring and is monitoring motion, or is executing a Safe Stop.
• the safety option is configured for Safe Limited Speed with Door Monitoring and the safety option is not actively monitoring for Safe
Limited Speed, is in a SLS Monitoring Delay [LimSpd Mon Delay], or is executing a Safe Stop.
• the safety option is configured for Safe Limited Speed with Door Monitoring and Enabling Switch Monitoring, and
–
the safety option is not actively monitoring for Safe Limited Speed, is in a SLS Monitoring Delay [LimSpd Mon Delay], or is
executing a Safe Stop.
–
the safety option is actively monitoring for Safe Limited Speed when the ESM_In input is OFF and the DM_In input is ON.
This bit is always set to 0 when the safety option is not configured for Door Monitoring.
20
LM In
This bit is set to 1 if the logical value of the dual-channel LM_In input is evaluated as 1.
This bit is set to 0 if the logical value of the dual-channel LM_In input is evaluated as 0.
21
ESM In
This bit is set to 1 if the logical value of the dual-channel ESM_In input is evaluated as 1.
This bit is set to 0 if the logical value of the dual-channel ESM_In input is evaluated as 0.
22
ESM In Prog
This bit is set to 1 if the Safety mode is configured for Enabling Switch Monitoring, Safe Limited Speed monitoring is active, and the SLS_In
input is OFF. It is also set to 1 if the Safety mode is configured for Enabling Switch Monitoring and Door Monitoring and the DM_In input is
OFF.
This bit is set to 0 when the Safety mode is not configured for Enabling Switch Monitoring.
23
Reset In
This status bit reflects the state of the Reset_In input. A 1 indicates the Reset_In input is ON; a 0 indicates the Reset_In input is OFF.
24
Wait Reset
This bit indicates when an SS Reset is required. The bit is set to 1 whenever the safety option is successfully configured and is in the Safe State
or when Standstill Speed has been reached.
25
Wait SS Cyc
This bit indicates when the SS_In input must be cycled prior to a SS Reset being performed. The bit is set to 1 if the SS_In input is ON and a
fault is detected or the Wait Stop Request attribute equals 1. It is set to 0 if the SS_In input is detected as OFF.
26
Wait No Stop
This bit is set to 1 when a stop request is made by using the HIM stop button. It is set to 0 when the HIM start button is pushed, following a
reset, or at powerup.
27
SLS Cmd
This bit is set to 1 when the safety option is commanding the drive to operate in limited speed mode.
28
Stop Cmd
This bit is set to 0 when the safety option is commanding the drive to stop.
