Description

The Rexroth Indramat R911277658 (DKR02.1-W300Z-BE11-01-FW) is a drive controller built for performance and precision, offering continuous power delivery over a broad speed range for Indramat AC motors. This model features an integrated supply module connected via an X5 port to an AC 3 x 400 – 480 V power source, along with a connection for a holding brake and motor temperature monitor through an X6 port. A seven-segment H1 display is used for error diagnostics, while an RS232 serial interface allows a PC or VT terminal connection. The unit operates at a maximum current of 212 A and a maximum power of 93 kW, with 1800 W of heat dissipation, 1200 W of which is managed with a built-in blower unit. A bleeder resistor, cooled with a 24 V blower unit, dissipates energy during deceleration. Firmware should be ordered based on the unit's configuration and installed in the U5 slot. The controller operates at an ambient temperature range of +5 to +45 degrees Celsius and offers IP20 ingress protection. The product comes with a one-year global warranty from Indramat USA.
