Product Description:

The EM7004-0000 is an EtherCAT module produced by Beckhoff Automation. This module interface is optimized for the simultaneous connection of four servo drives. It features four integrated incremental encoders and is renowned for its high operation accuracy. For fast operation pre-processing, the digital output on this product can be connected directly through the incremental encoders. This function is parameterizable; all outputs operate with a 24-volt power supply. The plug connectors are galvanically isolated from each other and from the supply voltage. The minimum cycle time for this product is about 1 millisecond, while the typical current consumed via the E-bus is 280 milliamperes. The protection rating of this product is according to IP20; this means the product housing can only provide protection against large solid materials. The product should be installed in an additional control cabinet for optimum protection.

The EM7004-0000 can withstand mild vibrations according to EN 60068-2-6/EN 60068-2-27, it also has an EMC immunity that conforms to EN 61000-6-1/EN 61000-6-4. A Beckhoff Identification code is applied to the product as a Data Matrix Code (DMC) for easy identification. This code is machine-readable, and it contains information that the customer can use for handling and product management.

The EM7004-0000 module is fully system-compatible; it can be operated with any Beckhoff Coupler and Bus Terminal controller without any restriction. The product has an approximate length of 147 millimeters, a height of 100 millimeters, and a width of about 55 millimeters. Without the connection, this product has an approximate weight of 260 grams. The unique design of this motor allows for a variable installation position; however, the installation environment should not have a relative humidity higher than 95 per cent or an ambient temperature higher than 55 degrees Celsius.
