The R911295773 (DKR02.1-W200B-BA03-01-FW) is a Bosch Rexroth drive controller designed for demanding industrial motion control applications. This unit comprises a DKR02.1-W200B base, ESM 02.3 firmware, analog command interface card, auxiliary modules, and a configuration rated plate. It operates from a 400–480V AC supply with a 230V AC control voltage at 50/60 Hz. Thermally protected to IP20, it uses air cooling via a built-in blower. Continuous current ratings reach 120 A (47 kW at 4 kHz) or 95 A (37 kW at 8 kHz), with a maximum bearing temperature of +55°C. The device supports digital servo and resolver motor feedback with a rated current of 200 A and includes a bleeder configuration.

Frequently Asked Questions

How does the DKR02.1-W200B-BA03-01-FW manage excess energy during braking cycles?

It uses an integrated bleeder resistor to dissipate regenerative energy as heat. This prevents overvoltage conditions in dynamic applications such as CNC spindles or presses.

Can analog interfaces limit system integration flexibility?

Analog control simplifies compatibility with older equipment but offers less precision than modern fieldbus systems. It’s most suitable where retrofit or straightforward control is needed.

Why does the unit weigh over 100 kg, and what does that imply for installation?

The weight reflects robust construction and large heat management components. Proper mounting and lifting equipment are necessary for safe handling.

How does the rated current of 200 A influence motor compatibility?

It supports high-capacity motors requiring significant continuous current. This makes it suitable for large-scale mechanical drives with demanding duty cycles.

How does running on 3×AC 400–480 V affect deployment?

It requires a compatible industrial power supply, common in Europe and North America. Voltage mismatches could damage the unit or reduce efficiency.
