Product Description:

The DKC14.3-100-7-FW is a modular drive controller produced by Bosch Rexroth Indramat and supplied in the DKC Drive Controllers series. It is classified as an EcoDrive unit and is intended to regulate torque, speed, and position for synchronous and induction motors used in conveyor, packaging, and handling stations. Installed between the facility mains and the field motor, the controller rectifies incoming three-phase power, stores energy on the internal DC link, and delivers controlled current to the machine axis according to commands from a higher-level PLC. Because it controls both motor current and axis response, the unit can support coordinated motion tasks where commanded speed changes and position updates must be translated into repeatable shaft movement.

The drive maintains a DC-bus nominal voltage of 700 V, providing a stable energy reservoir for rapid acceleration events and short-term load changes. Its output path is rated for a continuous current of 100 A, while the supply path can draw up to 40 A when the axis operates at full load. During steady-state operation, semiconductor switching and control electronics dissipate 420 W of heat, so the installation must provide enough airflow or cabinet cooling to remove that thermal load. A stable internal bus helps the inverter section supply the commanded motor voltage during dynamic moves, while the continuous current rating indicates the level the power stage can sustain under normal operating conditions.

The controller remains suitable for ambient temperatures up to 45 °C, allowing direct mounting inside standard electrical enclosures used on automation lines. Overall shipping weight is kept to 4.5 kg, so cabinet rails or slide-in sub-racks do not require heavy reinforcement. The device is built as Design 3, and Interface Option 14 provides compatibility with matching Indramat system wiring without auxiliary converter modules. The available interface format matches compatible system cables, and the moderate shipping mass reduces handling burden during installation.
