Application Proposals for Hardware Based Safety-Related Functions

Lexium 62 Variants C/D/G

The following table provides an overview of the possible application proposals for Lexium 62 variants C/D/G:

Single-channel application proposal

Proceed as follows to connect the variants C/D/G with single-channel Inverter Enable:

  1. Connect 9-pin connector at the CN11 connection.

  2. Connect the 24 V of the protective switching device to IEA_p1 or IEA_p2 or IEB_p1 or IEB_p2.

  3. Connect the 24 V to the connections CN6 or CN11.

Two-channel application proposals

If the lines are routed with protection, an error may be ruled out for example, control cabinet, armored conduit. Also see IEC 61800 and IEC 60204-1.

If the safety-related relay output has outputs generating, back-reading, and verifying test pulses, then an error detection is given. A protected wiring is not required.

Quantity of Channels and PL/SIL

The following table provides an overview of the same application proposals but from the aspect of the properties "quantity of channels" and "PL/SIL":

PL/SIL

Single-channel

Inverter Enable connection

Two-channel

Inverter Enable connection

PL e / SIL 3

Not possible

A maximum of 100 axes per safety function.

PL d / SIL 2

With more than 100 axes per safety function.
