Product Description:
The DDC01.2-K150A-D is a digital intelligent servo drive produced by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. This drive conditions power, monitors feedback, and executes PWM control so that synchronous or induction motors follow commanded torque, speed, and position profiles in automated machinery and material-handling cells. It serves as the power and control stage between the supply and the motor, allowing closed-loop operation in positioning, speed control, and torque control tasks. The unit is Series 1 and Version 2.
The power section is rated for 150 A continuous output, while the drive can maintain 45 A indefinitely without thermal derating and supply a momentary surge of 200 A for rapid acceleration. Internal bleeder circuitry dissipates regenerated energy at 0.25 kW continuously or up to 40 kW during short braking events. When tied to the mains, the maximum connected load is 22.5 kVA. Mechanical shaft power reaches 7.5 kW in continuous duty and 15 kW for S6-100 s operation at 90 A. This current reserve supports short, demanding motion changes without immediate output limitation. Cooling relies on natural convection, and line-to-motor conversion losses are held to 500 W. Digital servo feedback supplies high-resolution rotor data for accurate motor control.
For transient peaks, the inverter can drive 33 kW to the motor, provided the installation meets a minimum cabinet clearance of 300 mm and does not exceed 1000 m elevation. The enclosure is rated IP65, so it resists dust ingress and low-pressure water jets. Convection cooling means airflow must not be obstructed, and no fans are required. The PWM carrier operates at 4 kHz, balancing switching losses and current ripple for precise torque control. Acoustic emission remains within the Standard (100 A – 200 A) noise class.
