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).

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.

Alternately, the first SS_Out output may be used to signal a programmable logic controller (PLC) that a Safe Stop has been requested.

If the SS_In is ON (closed) and a successful Safe Stop Reset is performed, the

SS_Out output is turned ON.

If the Safe Stop is initiated or if a Safe Stop is initiated due to a fault, the SS_Out output is turned OFF.

If an error is detected on either channel of the dual-channel output, a fault occurs, which initiates the Category 0 Stop. The fault is latched until the drive is successfully reset.

For more information on faults, refer to Chapter 5

Safe Torque-off I/O Signals

Chapter 3

Safe Stop Reset

Safe torque-off drives provide a Reset Input (RESET_IN) for resetting the drive after a fault, and for synchronizing restart of several cascading drives. The Reset

Input (RESET_IN) is not safety certified and does not have dual-channel capability. Automatic reset functionality, if needed, can be achieved by hardwiring the RESET_REF and RESET_IN terminals together.

The Safe-off Reset (SO Reset) is a reset from the Safe-off State to the active safe monitor state. The reset is successful if the SS_In input is ON and no faults are present. The SO Reset occurs after the SS_IN inputs have transitioned to ON and RESET_IN is ON. After a successful SO Reset, RESET_IN may transition to the OFF state.

ATTENTION: A reset of the Safe Stop function can result in machine operation.

ATTENTION: The Safe Stop Reset does not provide safety-related restart according to EN 60204-1. Restart must be performed by external measures if automatic restart could result in a hazardous situation. You are responsible for determining whether automatic restart could pose a hazard.

When an SO Reset is requested, all diagnostic tests that can be performed prior to outputs being energized are performed prior to a successful SO Reset. If a diagnostic test can be performed only when outputs are energized, the test is performed immediately following the SO Reset.

Faults

If a fault occurs, the SS_In inputs in use must turn OFF and ON again to reset the GuardResetRequiredStatus bit before a successful SO Reset can occur.
