Speed Monitoring I/O Signals Chapter 4
Figure 7 - SLS_Out to SLS_In Connections for Multi-axis Applications
For more information on multi-axis configurations, see Cascaded Configurations
starting on page 97
.
For Safe Limited Speed Status Only modes, the SLS_Out output is used as an
indication that the Safe Limited Speed monitoring is active and the monitored
speed is less than the configured Safe Speed Limit. If the speed is greater than or
equal to the Safe Speed Limit, the SLS_Out is turned OFF. When Safe Limited
Speed monitoring is not active or the safety option is in a SLS Monitoring Delay
[LimSpd Mon Delay], the SLS_Out output is OFF. The SLS_Out output is
turned OFF when a Safe Stop has been initiated, a fault has occurred, or the
safety option is in the safe state.
See Safe Limited Speed Status Only Mode
on page 91 for more information.
If an error is detected on either channel of the dual-channel output, a fault occurs.
I/O faults are Stop Category faults, which initiate the configured Safe Stop Type.
The fault is latched until the safety option is successfully reset.
For more information on faults, refer to Chapter 12
