Product Description:

The DKR05.2-W700N-BE30-01-NNNN-FW is a digital intelligent AC drive controller produced by Bosch Rexroth Indramat for the DKR Drive Controllers series. It supplies regulated power to large synchronous or induction motors in high-demand motion systems. The unit exchanges motion commands with higher-level automation systems for coordinated axis control. This makes it suitable for presses, gantries, and other energy-intensive manufacturing equipment where stable torque and speed control are required. It is intended for applications where large motors must follow programmed motion profiles without sacrificing continuous power capability.

This model supports closed-loop positioning through digital servo and resolver feedback and communicates with CNC or PLC hardware over the SERCOS interface. The feedback arrangement gives the controller the position and speed information needed for accurate response during acceleration, deceleration, and load changes. A nominal current of 700 A lets the unit propel motors with a rated power of up to 245 kW when the mains voltage is 400 V. That output level suits large axes that demand high continuous torque from the power stage. Internal losses reach 9.5 kW, and heat is removed by a built-in air blower so no external heat exchanger is required.

The cabinet weighs 650 kg, so it requires a fixed mounting surface and suitable handling equipment. Its housing is finished in pebble gray and secured with a 7 mm three-square lock, while no door-mounted main switch is fitted. The design uses a rigid DC bus without a brake chopper, which reduces component count in the power section. If the application produces continuous regenerative energy, external braking resistors are required. The enclosure also omits an internal door switch, leaving disconnect and cabinet interlock choices to the surrounding system layout.
