Bosch Rexroth DKC01.1-040-7-FW Servo Drive Controller

Product Description The DKC01.1-040-7-FW is a compact, single-axis AC servo amplifier from the Bosch Rexroth Indramat ECODRIVE DKC01.1 series, engineered for high-voltage (380–480 V AC) precision motion control. The FW suffix indicates firmware is ordered separately (not factory preloaded), allowing user selection of application-specific firmware. It pairs with Indramat MKD/MKE series servo motors for medium-to-high power automation tasks.

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
