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 manages the DC-bus energy that feeds axis inverters. 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 power channel delivers a continuous output of 40 A and will accept the same peak current for short transients, 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. Vector modulation is updated against an 8 kHz carrier, and commanded motor frequency can reach 800 Hz. 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.
