Core Functions

Three-loop control (current/speed/position) for precision motion

Basic unit design: flexible for custom interface upgrades (analog, SERCOS, PROFIBUS)

Internal cooling saves cabinet space for dense multi-axis layouts

Comprehensive protection: over/undervoltage, overcurrent, short circuit, overheat, feedback loss

Torque/speed/position control modes

Modular firmware/software: stored on U5 module for easy replacement

Application Scenarios

Low-to-medium power CNC machine axes

Textile, printing, packaging machinery

Multi-axis handling robots and assembly lines

General-purpose automation with resolver/digital feedback

Retrofits of legacy DIAX02 systems to DIAX03 firmware

Usage and Maintenance

Ensure unobstructed cabinet airflow for cooling efficiency

Keep ambient temperature ≤45 °C to avoid performance derating

Complete power, feedback, and control wiring before power-on

Configure parameters via IndraWorks according to application requirements

Clean air ducts and heatsinks every 6 months; inspect terminal connections

Calibrate control loops and feedback signals annually
