Product Description
The EP7041-3002 digital input module from Beckhoff's EP Series provides reliable and versatile stepper motor control. Weighing only 165 grams, its lightweight construction allows for easy integration into machinery while maintaining robust durability. At its core, the module supports two digital inputs to interface with an encoder system for closed-loop position feedback, ensuring precise motor positioning even under load variations or dynamic conditions.
Processing signals through the EtherCAT protocol enables high-speed communication up to 8000 full steps per second. This level of configurable step frequency provides smooth and responsive motion for many automation tasks. Internal current controllers dynamically regulate output to the 2-phase stepper motor between nominal voltages of 8-48VDC. Peak output currents of 2x5A, combined with overload and short-circuit protection, allow tight torque control in demanding applications. Protection ratings of IP65, IP66, and IP67 shield the module from dust, water, and other environmental hazards. Its dependability is further strengthened through diagnostic LEDs monitoring critical functions like step loss, while distributed clocks maintain synchronization across the EtherCAT network. Additional I/O includes a 24VDC digital output to trigger external devices in tandem with motor motion profiles.
An encoder resolution as high as 5000 positions per revolution allows for nimble positional accuracy. The 256-fold microstepping feature multiplies this resolution for ultra-fine motion smoother than a full step, enabling users to program custom step patterns tailored for each mechanism. Overall, the module eliminates uncertainties through closed-loop feedback for repeatable performance over extended runtimes. All configuration and programming take place through the EtherCAT interface, which enables fast setups and seamless integration into distributed control architectures. No additional fieldbus connections are needed, streamlining wiring. The M12 connector provides quick connect/disconnect for swapping modules during maintenance or upgrades.
