Safety Functions Option 3 (FSoE, SIL3 PLe)

The safety functions on the AKD2G with functional safety option 3 are certified.

The drive is ready to operate with a pre-configured STO function.

Each safety function can either be activated through FSoE, digital input, both. Configure the source of activation inside the safety parameters so it matches the system requirements.

Review the default setting and check if it matches the requirements. If it does not match, modify and validate the safety parameters.

For Digital I/O commanding, use WorkBench to map safety functions to Safe I/Os.

With FSoE the safety functions can be activated with the safePLC of the FSoE Master.

With dual axis drives every safety function can be activated for either one axis or for both axes (axis 1 or axis 2 or axes 1 and 2).

The systematic safety integrity indicated by the systematic capability can be achieved only when the instructions and constraints are observed. Where violations occur, the claim for systematic capability is partially or wholly invalid.
