ETEL DSCDP121‑111E‑000A Dual Driver Board

The ETEL DSCDP121‑111E‑000A, also known as the 1041E‑040‑02D driver board, is a high‑density dual‑axis servo drive module designed for space‑sensitive multi‑axis motion control. This board integrates two independent drive channels, each capable of controlling a separate motor with its own feedback and control loops. It is an ideal solution for applications such as dual‑axis gantries, stereo microscopes, and compact robotic joints where multiple axes must be controlled within a limited footprint.

Key Attributes

• Dual‑Axis Integration: Two complete servo drives on a single board, reducing component count and wiring.

• Independent Control: Each axis can be tuned separately for optimal performance.

• EtherCAT Interface: High‑speed communication for synchronized operation with other modules.

• Flexible Feedback: Supports incremental, absolute, and Sin/Cos encoders per axis.

• Compact PCB Form Factor: Designed for direct integration into OEM electronics.

Technical Specifications

• Supply Voltage: 24‑48 VDC (common for both axes)

• Continuous Current per Axis: 2.5 A / peak 5 A

• PWM Frequency: 30 kHz

• Feedback per Axis: Incremental (RS422), Absolute (BiSS, EnDat), Sin/Cos

• Communication: EtherCAT (CoE), CANopen

• Digital I/O: 4 inputs, 4 outputs (shared)

• Dimensions: 150 × 100 × 15 mm (board only)

• Protection: Overcurrent, overvoltage, overtemperature

Applications

This driver board is widely used in OEM equipment such as automatic pipetting stations, optical zoom systems, and miniature machining spindles. Its dual‑axis capability allows compact designs without sacrificing performance.

Integration Support

ETEL provides a comprehensive development kit for integrating the DSCDP121‑111E‑000A into custom systems. The board includes a 40‑pin header for all connections, and a detailed reference design guide assists with PCB layout and thermal management. The EtherCAT stack is pre‑integrated, reducing development time.

Conclusion

The ETEL DSCDP121‑111E‑000A dual driver board offers a powerful, space‑efficient solution for dual‑axis motion control. Its high integration and robust performance make it a preferred choice for innovative machine designers.
