Product Description:
Bosch Rexroth Indramat manufactures the DKC02.3-100-7-FW in its DKC Drive Controllers series. Classified by the company as an EcoDrive unit, this controller supplies regulated three-phase power to servo motors and lets a PLC or CNC issue motion commands through the designated Interface option 02. The product modulates voltage and frequency so that axes in material handling, packaging, or assembly equipment follow position, speed, and torque references precisely.
The electronic section is tied to a DC-bus nominal level of 700 V and can raise the output to as much as 800 V line-to-line while delivering a peak of 100 A; the same value also defines its rated current for continuous operation. Carrier modulation supports frequencies up to 1000 Hz, allowing finely stepped velocity profiles. Internal losses are limited by a continuous power dissipation of 420 W, and the control logic draws only 26 W from a 24 V supply. The brake relay tolerates 250 000 switching actions shorter than 50 ms, handles up to 4 A at 40 V, and still registers reliably with a minimum contact load of 100 mA. Design version 3 within series 02 assigns firmware format, parameter memory, and diagnostic behavior.
The housing measures 105 mm wide, 360 mm high, and 261 mm deep; it weighs just 9.7 kg, so cabinet rail mounting is uncomplicated. Thermal limits permit continuous duty up to 45 °C; operation may continue to 55 °C with derated current. The 80 mm bottom and 150 mm top clearances maintain airflow around the heat sink. Control electronics consume only 26 W, a figure helpful when sizing auxiliary power supplies. Installation crews note that enclosure depth and weight align with the specified minimum clearances, ensuring convection cooling sustains component life across 250 000 brake cycles and other rated stresses.
