Product Description:

The DKC01.3-LK-EAK02 is a motion control module built by Bosch Rexroth Indramat within the DKC Drive Controllers series. As an EcoDrive controller, it translates command data into precise electrical pulses for servo axes used in packaging lines and material handling cells. By integrating power electronics with programmable interfaces, the unit provides velocity, position, and torque regulation so a PLC can coordinate multiple axes. It slots into a modular rack next to related power supplies and communicates through incremental and serial encoder feedback channels to maintain closed-loop accuracy in real time.

The controller accepts process variables through four differential analog channels. Each channel resolves signals to 12 bits, giving 4096 discrete steps. Input voltage swing is accommodated over a bipolar 10 V span, so sensors centered on zero can be read without offset scaling. Up to 4 configurable analog inputs can be assigned to current, speed, or torque loops. Internally, position computations refresh on a 1000 µs cycle, and the integrated pulse generator can toggle outputs as fast as 1 MHz, maintaining square-edge fidelity for high-resolution incremental encoders. Gray-coded SSI words carry 24 bits of absolute position data after a 650 ns delay to the drive processor.

For position feedback, the module offers three differential incremental channels routed with RS422 signaling, minimizing electromagnetic interference. The encoder link supports cable runs up to 40 m, and the motor-side junction uses a MiniDIN 8 connector for quick alignment during service. Cabinet I/O terminates on a 9-pole spring-tension block that matches design 3 format. Downstream circuitry must respect an output load capacitance of 10 nF to keep edge timing within limits. When line voltage disappears, the controller drives its power-failure bit LOW so that supervisory logic can initiate a controlled stop.
