Safe Torque-off I/O Signals Chapter 3
Reset Input (Reset_In)
The Reset input is for reset and monitoring of the safety circuit. RESET_REF
provides reference voltage for the RESET_IN input.
For automatic reset option, wire the reset input terminal (IOD-26) to the
RESET_REF terminal, (IOD-25).

Outputs
The drive has safe-stop safety control outputs.
See the specifications in Appendix
A to verify your power requirements.
Safe Stop Output (SS_Out)
The safe state for this signal is OFF.
These outputs are typically used in multi-axis applications. In multi-axis
applications, you can use these outputs to daisy-chain the master drive to a slave.
For SS_Out to SS_In_CH2/3 cascaded signals, the interface is a dual-channel
sourcing solid-state safety output connected to a dual-channel safety input. The
outputs are pulse-tested.
