Product Description:

The DKR 3.1-W200Z-BE34-00 is a digital intelligent AC drive controller produced by Bosch Rexroth Indramat and assigned to the DKR Drive Controllers series. It is mounted in automation cabinets to control three-phase servo or spindle motors, converting incoming line power into regulated output that follows changing load commands. By handling current and velocity control inside the unit, it links higher-level motion systems to the actuators used in machining centers, pick-and-place gantries, and other automated equipment. This arrangement lets the drive respond quickly to command changes while maintaining stable motor behavior during speed regulation and positioning tasks. It is suited to applications that require repeatable speed control and responsive torque delivery.

Communication with higher-level CNC or PLC equipment is handled through the SERCOS interface, which uses a fiber-optic ring for real-time position, velocity, and diagnostic data. The power stage delivers a continuous current of 141 A under rated thermal conditions, and short acceleration or deceleration intervals can draw up to 200 A of peak output. Excess heat is removed by a built-in air blower, so the controller can operate in a standard control cabinet without external ducting. For position feedback, the unit accepts digital servo and resolver feedback, allowing it to work with different encoder technologies. This combination supports closed-loop motor control while keeping communication and feedback handling inside the same drive platform. It can serve axes that require stable motion during rapid changes in load and speed.

The unit is Design Version 1. It uses Function Module Version 00, which indicates the standard module arrangement without an added technology module. These identifiers distinguish the product generation and module layout used by this controller. They are useful when matching the drive to existing hardware layouts and documentation in installed systems. The version coding also shows that this build follows the base functional format for the model rather than a specialized option set. That makes the controller easier to identify within larger multi-axis cabinet assemblies.
