The Rexroth Indramat MPN R911277658 (DKR02.1-W300Z-BE11-01-FW) is a drive controller designed for precision operation of AC motors. It includes an integrated supply module for connection to a 3 x 400–480 V AC power source via an X5 port and provides holding brake and motor temperature monitoring through the X6 port. Continuous output is supported, with a maximum rated current of 212 A and power output up to 93 kW. The unit features air cooling with a built-in blower to handle 1200 W of the 1800 W total dissipated heat and uses a bleeder resistor with a 24 V blower for energy dissipation during deceleration. Diagnostic functions are available through a seven-segment H1 display and error reporting, while an RS232 interface allows PC or VT terminal connections. Firmware installation is required in the U5 slot, configurable to application needs. The module operates within a temperature range of +5 to +45 °C, meets IP20 protection standards, and supports SERCOS command interface, digital servo and resolver motor feedback, and nominal current rating up to 300 A.

Frequently Asked Questions

What applications benefit most from the DKR02.1-W300Z-BE11-01-FW?

It is ideal for high-inertia loads such as conveyors or presses where constant torque delivery is essential. Its fast communication and control loops enable precise motion in complex automation systems.

How does the real-time interface improve motion control performance?

Deterministic communication ensures drive commands and feedback are synchronized with the PLC cycle. This minimizes jitter and improves contour accuracy in multi-axis setups.

What happens if the blower cooling system is obstructed?

Restricted airflow can lead to thermal shutdown or derating to protect power electronics. Regular cleaning and unobstructed ventilation paths are critical to sustained performance.

Does the 300 A rating allow for oversizing motors?

It supports motors with high current demand, but thermal limits of both drive and cabling must be considered. Oversizing without proper heat management may shorten component life.

How does resolver feedback influence system reliability?

Resolvers are robust in noisy environments and tolerant to heat, making them well-suited for harsh conditions. However, digital encoders offer finer resolution where precision is critical.
