Product Description:

The EP7041-1002 digital input module is designed to provide precision stepper motor control. Utilizing the EtherCAT protocol, it delivers efficient and configurable operation in a compact casing that weighs approximately 165 grams. The device supports connection via an M12 socket with 5 pins coded for reliable linking. Optimized for stepper motor applications, the EP7041-1002 works with 2-phase motors within a nominal voltage range of 8 to 48 V DC, accommodating various motor specifications. A peak current output of 1.5 amps allows adequate power delivery for demanding loads, while the module operates internally at around 30 kHz for smooth rotational control.

Microstepping is a key feature, with 64 configurable levels providing finer resolution over standard full steps. At the maximum setting, position accuracy approaches 5000 points per revolution for demanding motion profiles. Step frequencies can be tuned up to 8000 full steps per second to support rapid sequences. Versatile I/O capabilities include 2 digital inputs to monitor external conditions and 1 digital output for coordinated control. An encoder interface with 24 VDC compatibility enables closed-loop positioning through feedback. Internal diagnostic circuitry continuously monitors operation for fast troubleshooting.

Rugged construction affords best-in-class protection with an IP65, IP66, and IP67 rating, shielding against dust, water, and other process elements. Connectors utilize M8 and M12 industrial specifications for dependable mating even in harsh industrial settings over extended periods. Intuitive LED indicators on the module housing provide real-time performance visualization, allowing users to easily check for error conditions affecting the A and B motor phases, loss of synchronization steps, as well as power and enable statuses. Together with EtherCAT communication, this extensive diagnostics streamlines maintenance and problem resolution. Programmable functions allow for optimizing settings to application needs. Step frequency, microstepping level, I/O functionality, and more can be customized through parameterization. Preset initialization and integrated clocks further enhance synchronization in automated machinery for smooth sequential coordination.
