Beckhoff EtherCAT Box system: EP7041 motion box for the control of stepper motors

Stepper motor and incremental encoder interface in one IP 67 box

Using the EP7041 stepper motor module, EtherCAT motion applications can now also be realised directly in the field without an additional control cabinet. Ideal for harsh environments, the compact EtherCAT module in protection class IP 67 allows the connection of stepper motors up to 50 V DC and 5 A. An integrated incremental encoder connection permits the implementation of a single servo axis with a compact IP 67 module.

The EP7041 EtherCAT Box is intended for the direct connection of stepper motors up to 50 V DC and 5 A. In its compact housing, which measures 126 x 30 x 26.5 mm (H x W x D), the EP7041 contains an encoder connection, two digital inputs for limit switches and a digital output for a brake. This way, all signals from a motor are combined in one box. In addition to the modules designed for 5 A, there is also a 1.5 A version (EP7041-1002) for the control of lower power stepper motors. With just a few parameters, the EP7041 EtherCAT Box can be adapted to the motor and the application. The particular highlight of the stepper motor module is the 64-fold micro-stepping, which ensures a very smooth and precise motor rotation. The stepper motor modules are thus particularly well-suited for use in the feed axes of handling and processing machines and in assembly technology.

Beckhoff offers a corresponding range of stepper motors with standstill torques ranging from 0.38 to 5 Nm.
