Product Description:

The DKR03.1-W100Z-BE12-01-FW is a drive controller built by Bosch Rexroth Indramat. In an automation cell, this unit supplies regulated three-phase power to synchronous or induction motors while exchanging real-time motion commands with a CNC, PLC, or robot master. By closing the velocity and position loops inside the controller, it coordinates axis movement and helps protect connected actuators from overspeed, stall, and thermal overload during demanding motion cycles. The controller also regulates current during acceleration and deceleration so motor response remains stable as load conditions change. That makes it suitable for coordinated motion on transfer systems, indexing equipment, and other automated axes that require accurate speed and position control.

This model communicates over the SERCOS interface, a fiber-optic protocol that supports deterministic cycle times for multi-axis coordination. Thermal management relies on a built-in air blower; the internal fan moves cabinet air across the heat sink so external ducting is unnecessary. The power stage accepts digital servo and resolver feedback, allowing the controller to operate with motors fitted with either sensor type. The unit is Design Version 1 and belongs to Line 03.

The unit uses Function Numeric Version 01, which supports motion functions such as electronic gearing and drive diagnostics. As part of the DKR Drive Controllers series, it uses the same style of parameter structure, diagnostic codes, and plug-in option slots found across related modules. This compact controller is intended for high-power vertical axes or gantry systems where modular expansion and forced-air cooling are needed within a single 24 V logic and 600 V DC link platform. Its layout suits cabinet installations where several coordinated axes must share common control architecture without sacrificing feedback flexibility.
