iC7 Functional Safety

3.1

Functional safety option +BEF2 includes Safe Torque Off (STO) and Safe Stop 1 time-controlled (SS1-t) safety functions. Drives with +BEF2

also include an advanced safety unit, which enables configuring functional safety parameters using MyDrive® Insight.

3.2

An additional advanced safety unit is used to implement safety functions in accordance with the standard EN IEC 61800-5-2 in iC7 system

modules with +BEF2.

The advanced safety unit handles the safe I/O and the monitoring of active safety functions. The advanced safety unit does not handle

the controls of the AC drive. The AC drive can be controlled, for example, with the drive application, or the external process control

system.

The advanced safety unit can be controlled with the digital I/Os and over safe fieldbus, where applicable.
