Digital I/O: 6 isolated inputs / 3 isolated outputs (basic configuration)

Service port: RS232 (IndraWorks setup/diagnostics)

Core Functions

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

B-type flexibility: Customizable via plug-in cards (SERCOS, analog, safety I/O)

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 design for easy maintenance/upgrades

Application Scenarios

High-power CNC machine axes (50 A continuous current demand)

Textile/printing/packaging machinery (heavy-load multi-axis sync)

Automated assembly lines & handling robots (high-torque applications)

Automation systems requiring custom interface expansion (SERCOS/analog/safety)

DIAX03 system upgrades with scalable high-power servo control

Usage and Maintenance

Ensure unobstructed cabinet airflow (maintain cooling efficiency for 50 A operation)

Keep ambient ≤45 °C to avoid performance derating

Complete power/feedback/control wiring before power-on

Configure via IndraWorks (match motor/load parameters; install optional comms/safety cards first)

Clean air passages/heatsinks every 6 months; inspect terminals

Calibrate control loops/feedback annually for stability
