Solidot S2E Series Stepper Drive

The Solidot S2E Series EtherCAT bus Stepper Drives comprise three models: S2E-T60B, S2E-T60K and S2E-T42B. The series uses a high-performance bus control solution and integrates Intelligent Motion controller functionality. It supports CoE (CANopen over EtherCAT) and complies with the CiA 402 standard, with a minimum Synchronization Cycle of 100 µs for microsecond-level refresh and multi-axis synchronization. It covers both open-loop and closed-loop control requirements, providing a unified bus drive solution for multi-axis coordinated motion and high-precision automation applications such as semiconductor equipment, laser processing, dispensing and bonding, and logistics sorting.

Model selection depends mainly on two points: first, the control requirement — choose S2E-T60B or S2E-T42B when closed-loop positioning accuracy is required, or S2E-T60K for open-loop control; second, the motor specification — choose S2E-T60B or S2E-T60K for motors of 60 frame and below, or S2E-T42B for small motors of 42 frame and below. The main parameters of the three models are compared below:

High-speed EtherCAT bus

Supports CoE (CANopen over EtherCAT) and complies with the CiA 402 standard, with a minimum Synchronization Cycle of 100 µs for microsecond-level refresh and multi-axis synchronization. Supports linear, star, tree and ring network Topologies.

Versatile control modes

Supports CSP, CSV, PP, PV, Homing and other modes to meet various host control requirements.

Selectable open-loop/closed-loop

S2E-T60B and S2E-T42B feature a built-in incremental encoder; in closed-loop operation they provide real-time feedback and automatically correct position errors to eliminate step loss. S2E-T60K has no encoder and a simple design, and is compatible with two-phase/3-phase stepper motors.

Complete interfaces

4 optically isolated digital inputs (default: positive/negative limit, home position, motor free/disable) + 2 optically isolated digital outputs (30 V/100 mA, common cathode), with configurable function and polarity; the brake port outputs 24 V directly, no additional relay control required.

Stable and reliable

.. 80 V DC/18 ... 50 V AC wide-voltage power supply, suitable for a variety of power environments, with fault detection and protection for overvoltage, overcurrent, undervoltage and excessive position error.

Easy commissioning

Digital display buttons replace DIP switches, and a 4-digit 7-segment LED display shows operating and fault information in real time; supports parameter setting, monitoring, jog test run and parameter management, plus a type-C commissioning interface.

Compact design

Programmable small-size design saves installation space in the electrical cabinet.

The above is an introduction to the Solidot S2E series stepper drive products.
