Product Description:

The DKC05.3-100-7-FW drive controller is produced by Bosch Rexroth Indramat for the DKC Drive Controllers series. It is a closed-loop power stage that governs torque, speed, and position of servomotors in automated machinery, allowing coordinated motion sequences and diagnostic feedback inside industrial assembly cells and material-handling stations. The unit links directly to a multi-axis supply section, enabling decentralized motion groups without separate converters. This arrangement supports compact drive system layouts where several axes share a common power source.

The controller operates from a DC link stabilized at 700 V, so the connected power system must match this bus level to avoid undervoltage faults. Its thermal design supports a continuous motor output of 100 A, which is the continuous current available to the axis. During startup or transient loading, the mains side must furnish up to 40 A of input current. Code 3 marks the internal version used for this unit. Under full continuous current, the unit dissipates 420 W as heat, so forced-air cooling is required for operation. This heat load must be removed from the enclosure by directed airflow to maintain stable internal temperatures.

This model belongs to the EcoDrive product type, which supports braking energy transfer back to the shared bus. The enclosure weighs 4.5 kg, which helps simplify mounting on DIN rails or panel plates. Its specified ambient limit is 45 °C, and operation above that temperature may require output derating. Communication and command signals are routed through interface option 05, which provides standardized connectors for parameter access and system integration. Mounting the unit in an upright position helps preserve normal airflow through the housing and supports proper cooling performance.
