Core Functions

• Three‑loop control (current/speed/position) for high precision

• DA01 dual interface: DSF + analog emulation for legacy compatibility

• Internal convection cooling for standard cabinet installation

• Comprehensive protection: over/undervoltage, overcurrent, short‑circuit, overtemperature, feedback loss

• Control modes: torque/speed/position

• Modular design for easy maintenance and expansion

Application Scenarios

• Heavy‑load CNC main axes (mixed digital/analog systems)

• Large textile, printing, packaging machinery with legacy analog controllers

• Heavy‑duty gantries, conveyors, automated lines

• DIAX02 retrofits requiring 150 A + digital/analog feedback

• Cabinet‑space‑limited equipment without external cooling

Usage & Maintenance

• Ensure unobstructed cabinet airflow for cooling

• Keep ambient ≤45 °C to avoid derating

• Complete power/feedback/control wiring before power‑on

• Set parameters via IndraWorks (motor/load‑specific)

• Clean heat sinks/air passages every 6 months; inspect terminals

• Calibrate loops/encoder signals annually
