Product Description:
Bosch Rexroth Indramat manufactured the DKC06.3-040-7-FW for inclusion in the DKC Drive Controllers series and classifies it as an EcoDrive unit for closed-loop motion control in automated machinery. Configured as design 3, the controller interfaces with servo motors through its option 06 communication slot and uses its internal DC bus and inverter stage to supply controlled three-phase output to compatible Rexroth Indramat motors. By combining internal power handling functions with logic supplied from a 24 V DC control rail, the drive coordinates speed, torque, and stop commands inside multi-axis production lines.
The DKC06.3-040-7-FW is a 40 A type-current unit while the internal DC-bus is stabilized at 700 V. Heat generated by its IGBT bridge is removed by an internal blower, and total device dissipation reaches 180 W. Control electronics draw only 20 W from the 24 V input, minimizing auxiliary supply loading. With enclosure protection of IP20 it is intended for cabinet mounting. The switching frequency is selectable at 4 or 8 kHz, with maximum output frequency listed as 400 Hz at 4 kHz and 800 Hz at 8 kHz. A coupling capacitance of 200 nF limits radio-frequency leakage to the housing, and the ready contact can switch 1 A at 40 V DC with a minimum of 10 mA.
The energy recovery path includes a bleeder that handles 10 kW in short bursts, while no internal ZKS brake resistor is installed. Mains inrush is limited by a soft-start resistor of 60 Ω rated at 0.15 kW. The brake relay supplies 2 A continuously or during switching at up to 40 V DC, engages reliably down to a 100 mA load, and is certified for 250,000 operations. DC-link storage totals 0.27 mF, giving stable energy for rapid torque commands. The unit can be installed at sites up to 1000 m above sea level without derating, matching the hardware platform of these controllers.
