DKC04.3-040-7-FW

DKC04.3-040-7-FW is a Bosch Rexroth Indramat EcoDrive in the DKC Drive Controllers series. It uses design version 3 and interface option 04, which provides an INTERBUS-S communication interface for integration with an automation network. The controller has a rated current of 40 A and accepts a maximum input current of 16 A. Its DC bus has a nominal voltage of 700 V for supplying the drive power stage. At continuous current, the unit dissipates 180 W of power. It can operate at ambient temperatures up to 45ºC and weighs 5.7 kg.

The brake output supports a maximum continuous current of DC 2 A and a maximum loop current of DC 10 A. It switches up to DC 2 A at a maximum switching voltage of DC 40 V, while the minimum brake-contact load is 100 mA. The brake supply supports up to 100 µH of inductance, which limits the permitted inductive load in the brake circuit. Its brake-switching life is 250,000 cycles. For connected cables, maximum core-to-core capacitance is 0.5 nF/m, and maximum capacitance to ground is also 0.5 nF/m; these limits help maintain reliable signal and power behavior over the cable run.
