DDC01.1-K150A-R

The DDC01.1-K150A-R is a digital servo drive built by Bosch Rexroth Indramat and assigned to the DDC Digital Intelligent Servo Drives series. Used as the power and control interface between a supply module and an Indramat AC servomotor, the unit modulates current in real time so that axis position, velocity, and torque follow the programmed motion profile inside CNC and material-handling cells. It handles high current loops to energize synchronous motors while exchanging status data with machine controllers over the drive bus.

The drive is dimensioned for a continuous phase output of 150 A, allowing it to command large framed servomotors without reaching current fold-back limits. Heat is removed through natural convection air cooling, so cabinet layouts must provide vertical clearance for chimney flow rather than rely on forced ventilation. Rotor position is returned to the controller with resolver feedback, giving analog sine-cosine signals that remain accurate through high vibration and temperature swings. Classified by Indramat as a Digital Intelligent Servo Drive, the unit integrates its own microprocessor for adaptive current control and parameter storage. Acoustic output is rated as Standard (100A – 200A), signaling that the sound pressure stays within typical shop-floor expectations even when the drive is loaded near its current ceiling.

For integration tasks the unit carries the legacy identity of Bosch Rexroth Indramat, ensuring firmware and fieldbus options align with earlier Diax controllers. Within the DDC Digital Intelligent Servo Drives family it occupies Series 1, which matches hardware pinouts and parameter sets released during the first hardware revision cycle. Hardware revision is further narrowed to Version 1, so spare modules and option cards must share the same index to guarantee connector orientation and EEPROM compatibility. When these identifiers are matched, engineers can swap drives without axis retuning, preserving machine uptime while meeting thermal and acoustic constraints outlined above.
