Slave Modes for Multi-axis Cascaded Systems
Slave, Safe Limited Speed
Status Only Wiring Examples
These examples show two different Slave, Safe Limited Speed Status Only
configurations.
The first example is configured as a cascaded middle unit via the P20 [Cascaded
Config] parameter (Multi Mid). It has SS_In, SLS_In, and DM_In input
connections from the previous upstream safety option, as well as SS_Out,
SLS_Out, and DC_Out output connections to the next downstream safety
option.

IMPORTANT
The SLS_Out signals change state immediately based on the speed relative to
the Safe Speed Limit if the Safe Limited Speed Monitoring Delay (SLS Mon
Delay) is set to zero.
