DKC01.3-008-3-MGP-01VRS

The DKC01.3-008-3-MGP-01VRS is a Bosch Rexroth Indramat module from the DKC Drive Controllers series. Classified as an EcoDrive unit, it serves as a digital servo amplifier that transfers motion commands from PLCs to the torque needs of synchronous or asynchronous motors. Design number 3 defines its cabinet mounting, and series code 01 marks its electrical topology. With integrated power electronics and feedback processing, the controller delivers acceleration, speed regulation, and position holding without external contactors. Its control loops run at microsecond intervals to keep following error low.

The power stage is rated for 8 A, defining the maximum continuous phase current before derating. A shared DC link held at 300 V lets multiple axes exchange energy. During steady motion the drive supplies 1.6 A, yet it can produce 4.8 A for 400 ms to cover acceleration peaks. Apparent power is capped at 0.7 kVA. A base load of 0.5 A keeps control electronics alive, and a 4.7 Ω soft-start resistor sized at 17 W limits inrush. Interface option 01 connects to multi-interface, general-purpose firmware version 01, and the ordering sheet cites design version 3.

The housing carries a IP20 protection class, so the unit is mounted inside ventilated electrical cabinets. At 8 kHz switching the bridge dissipates 31.3 W, heat that must be removed to keep operation stable up to 55 °C ambient. The controller weighs 1.8 kg, easing installation on crowded panels. Rated data remain valid to 1000 m altitude; use to 2000 m is allowed with current derating. Up to 90 % relative humidity can be tolerated if condensation is avoided.
