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
