The R911291393 (DKR02.1-W200N-BE45-01-FW) is a Rexroth Indramat drive controller of the DKR02 series, featuring a rated current of 200 A and a control voltage power of 0.2 kVA. It operates with a system frequency of 50 to 60 Hz and supports power voltage input up to 380 V. The integrated blower provides air cooling capability, allowing for heat dissipation up to 1 kW through the air channel. This unit is designed for installation at elevations from 0 to 1000 m above sea level and for operation in ambient temperatures between 5°C and 45°C. The drive controller supports SERCOS command interface, digital servo and resolver feedback, and is specified without a bleeder or brake chopper, utilizing a rigid DC bus. The enclosure meets IP20 standards as per EN 60529, and the required accessory kit for installation is M1-RAC3.

Frequently Asked Questions

How does the DKR02.1-W200N-BE45-01-FW handle cooling during continuous operation?

It uses an integrated blower for forced-air cooling, reducing external fan requirements. This design ensures stable junction temperatures even under high current loads.

What advantages does the SERCOS interface provide in multi-axis control?

It enables deterministic communication with precise synchronization across multiple drives. This reduces jitter and improves coordinated motion in robotics and packaging lines.

Why is resolver and digital servo feedback integration useful?

It allows compatibility with both modern digital encoders and traditional resolver-equipped motors. This flexibility simplifies retrofit projects in older automation systems.

How does the DKR02.1-W200N-BE45-01-FW simplify version management in control systems?

The firmware versioning and modular design ensure consistent behavior across installations. This minimizes configuration mismatches when scaling or replacing drives.

What impact does compact packaging have on panel design?

The standardized DKR footprint reduces the required enclosure space. This helps when upgrading or retrofitting existing automation panels.
