Product Description:

The DKR02.1-W200N-BE32-01-FW is a digital intelligent AC drive controller produced by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. In multi-axis machining centers, material-handling cells, and printing lines, this controller supplies regulated power and closed-loop motion commands to synchronous and asynchronous motors. It coordinates velocity, position, and torque across the plant network. This arrangement supports synchronized axis behavior when several motors must respond to shared motion commands during continuous operation.

The drive exchanges setpoint and diagnostic data over the SERCOS interface, enabling deterministic fiber-optic communication with PLCs and other drives. When its PWM frequency is set to 4 kHz, the unit sustains a continuous output of 120 A, translating into roughly 47 kW of mechanical power for connected axes. Internal logic and I/O are energized by a control bus of AC 230 V ±10%, independent of the main power stage. Thermal stability is maintained by an air channel with a built-in blower, so forced ventilation allows the electronics and IGBTs to hold nominal current without external cooling accessories. The controller is built for a rigid DC bus and contains no brake chopper, so braking energy must be recovered elsewhere in the system.

During rapid accelerations, the inverter can deliver a peak current of 141 A, giving machines short bursts of extra torque for indexing or spindle ramp-up. It accepts a mains supply of 3×AC 400 – 480 V ±10%, matching common industrial feeders worldwide. At full load, it releases about 1600 W of heat, a figure that affects cabinet airflow and ambient temperature allowances. Installation must account for a transport mass of 104 kg and provide rigid mounting rails to support the controller’s weight. Resolver and digital servo feedback ports allow the controller to work with common motor feedback formats used on high-power motion axes.
