ETEL DSB2P124‑211E‑000H Digital Servo Amplifier Slave Drive

The ETEL DSB2P124‑211E‑000H is a high‑voltage digital servo amplifier designed specifically as a slave drive for large‑scale multi‑axis motion systems. Operating from a 300 VDC bus, this amplifier delivers high current output suitable for driving large‑frame linear motors and heavy‑duty rotary servos. Its slave configuration allows it to be easily integrated into a master‑slave topology, enabling synchronized motion across multiple axes with minimal communication overhead.

Distinctive Features

• High‑Voltage Operation: 300 VDC input enables high torque at low currents, reducing I²R losses.

• Slave Functionality: Designed to receive position/velocity commands from a master controller via EtherCAT, ideal for gantry or multi‑axis coordination.

• Robust Current Output: Provides 12 A continuous (24 A peak) to handle demanding loads.

• Multi‑Feedback: Supports incremental, absolute, and Sin/Cos encoders, as well as resolver inputs.

• Integrated Brake Control: Built‑in output for holding brakes, essential for vertical axes.

Technical Specifications

• Supply Voltage: 300 VDC (200‑350 VDC range)

• Continuous Current: 12 A / peak 24 A

• PWM Frequency: 20 kHz

• Feedback: Incremental, absolute (BiSS, EnDat), resolver

Application Scenarios

This amplifier is particularly suited for large gantry systems, heavy‑duty robotics, and machine tools with high inertial loads. Its slave mode ensures tight synchronization with other axes, critical for contouring and multi‑point positioning.

Integration and Safety

The DSB2P124‑211E‑000H features a dedicated slave interface that simplifies cabling and reduces master controller load. It includes Safe Torque Off (STO) and Safe Stop 1 (SS1) as standard, meeting SIL 2 / PL d. The unit's compact heat sink design allows operation in ambient temperatures up to 45 °C without derating.

Conclusion

For high‑voltage, high‑power multi‑axis applications, the ETEL DSB2P124‑211E‑000H slave drive offers exceptional performance and reliability. Its integration with ETEL's master controllers and third‑party systems makes it a versatile choice for advanced motion control architectures.
