Chapter 3 Safe Torque-off I/O Signals

Figure 5 - Cycle Inputs Required

An Input fault occurs if the inputs are discrepant for longer than one second.

For SS_IN_CH0/1, use TEST_OUT_0/1 as a reference signal, or a fault occurs.

For more information on I/O faults, refer to Troubleshooting the Safe Torque-off

Drive on page 33.

Discrepancy Time

The maximum discrepancy time between two inputs is 1.0 second. If both inputs

do not change within 1.0 second, an input fault is displayed, the safety circuit is

activated, and torque is removed from the motor.
