Product Description:

The DKCXX.3-100-7-FW is a drive controller from Bosch Rexroth Indramat that belongs to the DKC Drive Controllers series. It is an EcoDrive unit that supplies regulated DC-bus power to synchronous or induction motors and interfaces with higher-level motion controls inside automated assembly lines, packaging machinery, and material-handling cells. This arrangement allows the controller to manage torque and speed in response to machine commands while supporting repeatable axis movement during production.

The controller delivers a rated motor phase current of 100 A, allowing it to drive medium-to-large axes without derating. Mains draw is limited to a maximum input of 40 A, so upstream protection devices can be sized accordingly. Internal conversion stages operate on a DC bus that is stabilized at 700 V; under acceleration commands, the unit can raise its output terminals to 800 V while modulating carrier frequency up to 1000 Hz for fine torque resolution. These electrical limits produce 420 W of continuous thermal dissipation, so cabinet ventilation must remove that heat to maintain nominal performance.

Command electronics inside the EcoDrive are powered by a control circuit that accepts a regulated supply of 24 V and draws 26 W during normal operation. For dynamic braking, the integrated relay can interrupt DC loads up to 2 A at 40 V, and safety coordination is supported by a short-circuit rating of 42000 A rms, permitting installation on high-fault industrial feeders. The housing measures 360 mm in height, 105 mm in width, and 261 mm in depth, and it weighs only 4.5 kg, which helps it fit compact cabinet layouts. Ambient temperature limits extend to 45 °C at nominal data and remain serviceable up to 55 °C with reduced output.
