DKC06.3-040-7-FW

DKC06.3-040-7-FW is a Bosch Rexroth Indramat EcoDrive in the DKC Drive Controllers series. It uses design version 3 and interface option 06, which provides the option-06 control and communication connection arrangement. The controller accepts a 24 V DC control-voltage input and consumes 20 W of control power. Its maximum input current is 16 A, while the rated current is 40 A and the peak type current is 40 A. The nominal DC-bus voltage is 700 V, and the nominal DC-bus capacitance is 0.27 mF. Coupling capacitance to the housing is 200 nF.

The controller delivers a maximum output frequency of 800 Hz at an 8 kHz switching frequency. Device power dissipation is 180 W, and power dissipation at continuous current is also 180 W. An internal blower removes operating heat. The unit can operate at ambient temperatures up to 45ºC and at installation altitudes up to 1,000 m. Its IP20 enclosure protects against contact with large solid objects but does not provide water protection. The controller weighs 5.7 kg.

The mains soft-start resistor has a resistance of 60 ohms and a power rating of 0.15 kW, limiting inrush current during startup. Peak bleeder power is 10 kW for dissipating regenerated DC-bus energy. An internal DC-bus brake, or ZKS, is not present. The brake output supports 2 A DC continuously, switches up to 2 A DC at 40 V DC, and requires a minimum contact load of 100 mA. It is rated for 250,000 switching operations. The ready contact switches up to 1 A DC at 40 V DC and requires a minimum contact load of 10 mA, providing controller-ready status to external circuitry.
