Core Functions

High-current three-loop control (current/speed/position) for heavy-load dynamic response

DA02 interface provides enhanced encoder emulation (higher resolution, lower latency) compared to DA01, ideal for high-precision analog system retrofits

Compact internal cooling saves cabinet space; modular design supports flexible expansion

Full protection: overvoltage/undervoltage, overcurrent, short circuit, overheating, feedback loss

Supports torque/speed/position control modes for high-power motion applications

Application Scenarios

Heavy-duty CNC machine tools (milling/turning centers, grinding machines)

High-power robotics and automated assembly lines

Packaging, printing, and textile machinery

Metalworking and material handling equipment

High-precision multi-axis retrofits requiring enhanced analog-digital integration

Usage and Maintenance

Install vertically with adequate cabinet ventilation; avoid blocking airflow

Operate within 0–45 °C ambient temperature; derate at higher altitudes

Complete DC bus, control power, motor, and DA02 feedback wiring before commissioning

Configure parameters via IndraWorks; firmware module (DSM02.1-FW) ordered separately

Clean fan/heat sink every 6 months; inspect terminals and cables periodically

Calibrate control loops every 2 years to maintain stability
