Regenerative power capability

Parameterizable gear ratios and feed constants

Application Scenarios

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

Heavy-duty packaging, printing, and textile machinery

Automated assembly lines and material handling systems

380–480 V AC industrial automation environments

Retrofit of legacy Indramat DKC01.1 systems

Usage and Maintenance

Mount vertically with ≥80 mm bottom clearance and ≥150 mm top clearance for airflow

Verify input voltage matches drive 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
