Wiring for Multi-Axis Systems

Overview

If you use a single safety-related relay for several axes, connect the inputs of the safety modules eSM in parallel.

Do not connect the outputs of the safety module eSM in parallel.

Flyback Diodes

The outputs of the safety module eSM provide integrated protection against inductive voltage. Additional flyback diodes can slow down the switching behavior of contactors. Refer to Electrical Data Module for information on the maximum inductive load on the outputs.

Wiring Without eSM Terminal Adapter

Wiring With eSM Terminal Adapter

The eSM terminal adapter available as an accessory simplifies wiring of several safety modules eSM for multi-axis systems and chaining of the inputs and outputs for guard door interlocking.
