Built-in homing, jog, and point-to-point positioning

Comprehensive protection: overvoltage, undervoltage, overcurrent, overtemperature, short circuit

Regenerative power capability (supports external braking resistors)

Application Scenarios

High-power CNC machine tools (main/spindle axes)

Heavy-duty packaging, printing, and textile machinery

Automated assembly lines with high payloads

Material handling systems (conveyors, cranes, hoists)

380–480 V AC industrial automation environments

Retrofit of legacy Indramat DKC01.3 high-voltage systems

Usage and Maintenance

Mount vertically with sufficient top/bottom clearance for airflow

Verify input voltage matches 380–480 V AC rating before power-on

Use shielded cables for motor/encoder wiring; separate from power cables

Clean cooling fans/filters every 3–6 months (dusty environments)

Check terminal connections quarterly for tightness
