Built-in full protection against overvoltage, undervoltage, overcurrent, short circuit, overheating and feedback loss.

Supports torque, speed and position control modes for diverse motion requirements.

Modular design enables convenient function expansion and routine maintenance.

Application Scenarios

Light and medium load axes of CNC machine tools

Textile, printing and packaging machinery

Small multi-axis handling robots and assembly lines

Automation equipment adopting serial communication control

Retrofit projects of traditional servo systems

Usage and Maintenance

Maintain adequate airflow inside the cabinet after installation for effective heat dissipation.

Keep ambient temperature below 45 °C to prevent performance decline.

Complete wiring for power, feedback and serial lines before power-on commissioning.

Set operating parameters via IndraWorks according to field requirements.

Clean internal air passages and heat dissipation parts every six months and inspect terminals regularly.

Calibrate control loops and feedback signals once per year to sustain stable operation.
