Use of the safety function

Contents of this chapter

This chapter describes the use of the safety function with factory default settings.

Activating the safety function

1. Switch off the POUS switch.
When the POUS is activated, the following indications are shown:
• the drive control program has the warning Safe torque off active,
• the POUS indication lamp is on.
Note: The POUS indication is not SIL/PL-rated.
A5A0 Safe torque off is indicated when drive STO is activated.

Resetting the safety function

No manual reset is necessary after you have deactivated the POUS function. The reset
input of the POUS safety relay [A65] is set to autoreset mode at the factory. However, you
must reset the drive if it has tripped on a fault at the activation of the POUS function. The
drive reaction depends on the parameter settings. See section Parameter settings.
