Product Description:

The DKR02.1-W300N-BE34-01-FW is a drive controller assigned to the DKR Drive Controllers series. As a digital intelligent AC drive controller, it converts line power into a controlled DC bus and a three-phase motor output for precise torque and speed regulation of large servo motors used in presses, gantries, and material-handling cells. This operating role allows the drive to support heavy axes that need stable motor current during changing load conditions. It is intended for coordinated industrial motion systems where speed changes and torque demand must be controlled closely. The unit is line series 02, design version 1, and function module version 01.

Axis commands enter through the SERCOS interface, while encoder loops are closed with digital servo and resolver feedback. At a 4 kHz switching frequency, the unit delivers a continuous current of 141 A and drive power near 55 kW, which suits high-demand servo applications. Internal logic, I/O, and safety circuits are supplied from a separate AC 230 V ±10% control feed to keep the power stage isolated from auxiliary functions. Cooling relies on a built-in blower that forces air through the heat sink. This airflow helps remove internal heat from the power section during sustained operation.

The controller can supply up to 212 A during short acceleration peaks, and its power stage accepts utility voltages in the range of 3×AC 400–480 V ±10%. Under rated load, the electronics and switching devices dissipate about 1800 W, so the enclosure must provide enough airflow for heat removal. Despite its integrated fans, the unit weighs approximately 104 kg, and the mounting panel must be able to support that mass securely. The absence of a brake chopper means braking energy must be handled externally, while the rigid DC link keeps the internal power path straightforward.
