Product Description:
The DKC06.3-100-7-FW is an EcoDrive digital drive controller built by Bosch Rexroth Indramat for the DKC Drive Controllers series. The module conditions incoming power and converts DC-bus energy into regulated three-phase output for synchronous or asynchronous motors. Acting as the interface between a plant PLC and a servo axis, it supervises current, monitors motor feedback, and supports dynamic braking during positioning and speed control. This makes it suitable for packaging machines, material-handling equipment, and compact machining systems that require controlled motor response across repeated duty cycles.
During startup, the control circuit accepts a 24 V supply, draws 4.0 A of inrush current for 12 ms, and then settles at 26 W. A 200 nF coupling capacitance routes switching noise to the chassis to reduce electrical interference. The DC bus operates at 700 V and uses 0.675 mF of capacitance for short-term energy storage and recycling. The drive delivers 100 A of motor current for both rated and peak output, and its output reaches 400 Hz at a 4 kHz switching frequency or 800 Hz when the carrier is raised to 8 kHz. Semiconductor losses total 420 W, so the IP20 housing requires forced cabinet airflow, and the unit is design 3 with design version 3 and internal series 06.
The housing measures 105 mm wide, 360 mm high, and 261 mm deep, with a mass of 9.7 kg. Cabinet installation requires 80 mm of clearance below the unit and 150 mm above it, while ambient air can reach 45 °C at nominal output or 55 °C with derating. Regenerated energy is dissipated as much as 31 kWs through a braking network that includes a 24 Ω soft-start resistor rated at 0.5 kW and a 6 Ω Zks resistor. The enclosure is rated IP20, so the drive must be installed inside a protected cabinet where airflow and spacing can be maintained.
