KDA 3.3-150-3-DP0-W1

Product Description:

The R911289817 servo drive, labeled as KDA 3.3-150-3-DP0-W1, falls under the Bosch Rexroth Indramat KDA Spindle Drives family. It’s easy to spot by its build. That continuous output is marked high, with 150 amps always ready and a bulked-up peak output of 300 amps when requirements jump. Voltage support lands at 3 × 230/400 V AC, built to match a lot of factory layouts on the floor. Size is already on the heavy end—measuring about 235 x 450 x 300 mm—and that kind of frame hints at a system made for big duties. Total weight clocks in at 22 kg, so the housing comes built for action, not for show.

Protection level is IP20, so the casing keeps out fingers and most random objects while ventilation remains a focus. Cooling gets handled inside with an internal fan system, cutting down on dust build-up or outside interference in standard operation. No skipping Sercos tech here; this model offers Sercos communication, making digital integration tidier when connecting to modern automated control bays. Taking in supply voltage at 24 V DC for controls and sticking with either 50/60 Hz as the power supply frequency, the drive keeps a wide coastal fit for facility upgrades. A Resolver feedback type sits inside, which helps dial in the accuracy for spindle moves and motion coordination.

Industrial lines sometimes run brutal cycles, and this drive answers with steady current, so there’s less downtime switching or tuning. Connections run through the main bus and cable sets, locking into place quickly when units drop in for replacement. Even though the frame’s heavy, the install hangs in place and stays cool with onboard fans turning. All that amperage means the KDA can start and stop bigger jobs without hiccups.
