About this product

Leadshine ELD3-EC7005BM is a 200 W EtherCAT DC servo drive supplied as an open board with RJ45 communication and brake output. It is intended for compact robot motion systems and compatible servo mechanisms, with 5 A rated current and 12.5 A peak current stated by the Ver2.0 manual. It supports position, velocity and torque control modes, a second encoder, USB Type-C tuning and independent logic power. Manufacturer sources disagree on the main supply range and digital-input count; Specifications preserve each source-qualified claim. Exact firmware and installation suitability remain subject to the manufacturer documentation. Cover image: Manufacturer series image; size may vary.

Reported claim

Configuration: ELD3-EC BM RJ45; manual Ver2.0; PDF page 28. Two-channel claim only. Connector reference CN5 conflicts with CN2 in the I/O table/wiring; connector assignment is an explicit source hold.

Leadshine ELD3-EC DC Servo User Manual Ver2.0
STO module (CN5 connector) consists of 2 input channels.

Sto motor response

PWM is blocked; motor coasts under inertia

Reported claim

Configuration: ELD3-EC BM RJ45; manual Ver2.0; PDF page 28. No guaranteed stopping time/distance; not a mechanical holding brake.

Leadshine ELD3-EC DC Servo User Manual Ver2.0
It cuts off the motor current supply by blocking of PWM control signal from the power module. When the motor current is cut off, the motor will still move under inertia and stops gradually.

Storage temperature

−20 to 80 °C

Reported claim

Configuration: ELD3-EC BM RJ45; manual Ver2.0; PDF page 13. Condensation free; storage, not operation.

Leadshine ELD3-EC DC Servo User Manual Ver2.0
Storage: -20-80℃ (Condensation free);

Suitable load inertia wording

30 times smaller than motor inertia

Reported claim

Configuration: ELD3-EC BM RJ45; manual Ver2.0; PDF page 13. Literal manufacturer wording is retained as an unresolved engineering-meaning ambiguity; no numeric inertia ratio is derived.

Leadshine ELD3-EC DC Servo User Manual Ver2.0
30 times smaller than motor inertia

Usb communication

Modbus USB2.0

Reported claim

Configuration: ELD3-EC BM RJ45; manual Ver2.0; PDF page 13. USB tuning link; not an RS fieldbus-model identity.

Leadshine ELD3-EC DC Servo User Manual Ver2.0
Modbus USB2.0 (No need to connect driver to power supply)

Usb tuning

Type-C; parameters can be read/modified without main supply

Reported claim

Configuration: ELD3-EC BM RJ45; manual Ver2.0; PDF page 12. Tuning-port capability, not a motor-power source.

Leadshine ELD3-EC DC Servo User Manual Ver2.0
USB Type-C Modify or read driver parameters without connecting to main power supply

Velocity control modes
