Introduction

4-channel motion interface, axis/servo drive

The EtherCAT module EM7004 is an interface that is optimized for direct connection of 4 servo drives, whose "encoder simulation" feeds the module with RS485 signals. The compact module features 4 integrated incremental encoders, 16 digital 24 V_DC inputs and outputs, and 4 analog ±10 V outputs.

For fast preprocessing the digital outputs can be connected directly via the 4 encoders (PLS). This function is parameterizable. All inputs and outputs operate with a 24 V supply. Connectors X4, X5, X6 and X7 each feature an encoder input and an analog output. The connectors are galvanically isolated from each other and from the supply voltage. Connectors X0 and X1 with 16 digital inputs and X2 and X3 with 16 digital outputs enable 3-wire connection.
