Safe Torque-off I/O Signals

Introduction

This chapter describes the safe torque-off input and output signals of the

Kinetix 6200 and Kinetix 6500 drives.

Inputs

The Kinetix 6200 and Kinetix 6500 drives have two sets of dual-channel inputs.

Each dual-channel input supports the safe stop (SS) function of the drive.

The SS_IN_CH0/1 inputs are intended for connection to a non-switching

E-stop device (dry contact). It controls the safe-off request initiated by a

transition from ON to OFF.

The SS_IN_CH2/3 inputs are intended for connection to an OSSD device or as

a cascaded input from another safety axis. It controls the safe-off request initiated

by a transition from ON to OFF.

The SS_IN_CH0/1 inputs are electrically identical and rely on a pair of pulse

test outputs, TEST_OUT_0 and TEST_OUT_1.

When both channels are active, if one channel’s input terminal transitions from

active to inactive and back to active, while the other channel’s input terminal

remains active, both channels must go inactive at the same time before the

evaluated status may return to ON. This condition is called ‘cycle inputs

required’.

Only one pair of dual-channel inputs can be used at the same time.
