Minneapolis, Minn. – Beckhoff Automation has introduced the EP7041 EtherCAT® Motion Box, allowing for stepper motor control in a compact, machine-mountable device. Using the EP7041 stepper motor box, small EtherCAT motion applications can now be implemented directly in the field without a protective control cabinet.
Ideal for harsh environments, the compact EtherCAT module in protection class IP 67 allows the connection of Beckhoff stepper motors up to 50VDC and 5A. An integrated incremental encoder connection on the EP7041 permits the implementation of a single servo axis with the compact IP 67 module.
Within the housing, which measures 5-in. x 1.2-in. x 1-in. (126 x 30 x 26.5mm), the EP7041 contains an encoder connection, two digital inputs for limit switches and a digital output for a brake, ensuring that all signals from a motor are combined in one compact box. In addition to the modules designed for 5A, there is also a 1.5A version (EP7041-1002) for the control of lower power stepper motors. By entering just a few parameters, the EP7041 EtherCAT Box can be adapted to suit the motor and the application.
The stepper motor module is capable of 64-fold micro-stepping, which ensures a smooth and precise motor rotation. The stepper motor modules are particularly well-suited for use in the feed axes of handling and processing machines as well as in assembly technology. Beckhoff offers a corresponding range of stepper motors with standstill torques ranging from 0.38 to 5 Nm.
