Chapter 8 Slave Modes for Multi-axis Cascaded Systems
This example shows the last cascaded slave safety option in the system. It has
SS_In and DM_In inputs from the previous upstream safety option, but its
DC_Out output is connected to a guardlocking interlock switch. This unit is
configured with automatic reset so it follows the function of the previous axis.
Figure 31 - Slave, Safe Stop, Last Unit
This example shows three safety options connected together in a cascaded
system.
