Product Description:

The DKR 3.1-W200Z-BE32-00 belongs to the DKR Drive Controllers series from Bosch Rexroth Indramat. It is a digital AC drive controller used in multi-axis machining centers, material-handling cells, and other automated stations to regulate torque, speed, and position on connected servo motors. By combining closed-loop current control with fast communication, the unit coordinates motion profiles that must remain synchronized with higher-level PLC or CNC commands. This arrangement helps connected axes respond quickly to changing load conditions while keeping commanded motion stable during production cycles. It can therefore support coordinated motion where several axes must start, stop, and track position together under changing process loads.

The controller exchanges real-time setpoints and diagnostics through a SERCOS interface, allowing fiber-optic communication on a single ring network. Thermal management is handled by a built-in air blower; the internal fan moves cabinet air across the heat sink so no external coolant loop is required. The controller carries the 200 A current designation, supporting large frameless or spindle-rated servomotors. The unit is Design Version 1. Position feedback can be processed as digital servo and resolver feedback, so the controller can read high-resolution optical encoders or resolver signals without additional modules. That flexibility supports machine layouts that mix servo axes with resolver-based motor applications.

During rapid acceleration, the power stage can deliver a peak of 141 A for short bursts of added torque. The unit uses Function Module Version 00. The device is a Digital Intelligent AC Drive Controller, and its microprocessor supervises current loops, monitors faults, and records operating data that can be queried over the fieldbus. Stored status information gives the higher-level control a direct view of drive conditions during operation. This supports closed-loop motion systems that require deterministic communication and internal cooling.
