The Rexroth Indramat drive controller, MPN R911266946 (DKR02.1-W200Z-BE43-01-FW), features a five-slot modular configuration supporting software, command communication, and expansion via three additional interface modules. Slot U1 is designated for a SERCOS interface, while Slot U5 is used for firmware and operating parameter storage. Operating conditions are specified for use at elevations from 0 to 1000 meters and temperatures between 5°C and 45°C, with derated performance at higher elevations (up to 5000 meters) or temperatures (up to 55°C). Electrical input is 400–480V AC, three-phase, with an output rated at 200 A. The drive incorporates a built-in air-cooling blower and supports digital servo and resolver feedback. Maximum operational heat dissipation is 1600 W. The unit is housed in an IP20 enclosure and should be installed within an IP54-rated cabinet with dust filtration.

Frequently Asked Questions

What is the significance of the 200 A rating in the DKR02.1-W200Z-BE43-01-FW?

It defines the maximum continuous current the controller can supply to connected motors. This determines motor size compatibility and overall power capacity in demanding automation tasks.

Why does this controller use a built-in blower for cooling?

The integrated blower provides forced-air cooling, reducing thermal buildup during high current operation. This eliminates the need for external liquid cooling systems, simplifying installation.

How does digital servo feedback improve performance compared to analog methods?

Digital feedback reduces signal degradation over distance and provides higher resolution positioning. This leads to smoother motion profiles and tighter control loops.

Can the DKR02.1-W200Z-BE43-01-FW operate with multiple motor types?

Yes, it supports a range of AC servo motors configured for digital or resolver feedback. This flexibility allows it to be used across various machine setups.

In what type of machinery is the DKR02.1-W200Z-BE43-01-FW typically applied?

It is commonly installed in CNC machines, printing presses, and industrial automation lines. These systems demand high current and precise motion coordination.
