The R911270255 (DDC01.1-K150A-DS03-02-FW) is a Bosch Rexroth Indramat DDC 1.1 air-cooled drive unit with a rated current of 150 A. It is designed to operate at input voltages of three-phase 220 or 230 V, with a frequency range of 50 to 60 Hz and a 4 kHz PWM frequency. The drive includes a SERCOS command module and features standard noise emission for motors within the 50 A to 200 A range. To address radio interference, a suppression filter is required. The integrated bleeder resistor, which dissipates energy during braking, can generate significant heat; placement at least 300 mm from flammable materials is specified. Air outlet obstruction and improper cable routing can negatively affect performance. Voltage matching is achieved via transformer, and an isolating transformer is recommended for some installations, particularly with non-standard mains conditions or specific control enclosures. Operating temperature should not exceed 40°C.
