Product Description:

The DDC01.1-K150A-DL04-01-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat and delivered as part of the DDC Digital Intelligent Servo Drives series. Its integrated control and power stage forms the central axis module in industrial automation systems, converting low-level position commands into regulated three-phase power for a matched servo motor. This product is installed close to the machine to reduce wiring length and maintain high-resolution feedback between the motor and the drive, allowing packaging equipment, handling robots, and in-process transport mechanisms to follow stored motion profiles accurately.

At the power interface, the drive supplies a continuous phase current of 150 A, so matching conductors and protection devices must be selected for this load. It is designed for a three-phase AC connection and accepts utility frequencies of 50/60 Hz, allowing operation on standard plant power systems. Cooling relies on natural convection air cooling, so no fan or external heat exchanger is required because heat is dispersed through the finned housing. Setup and diagnostics use the RS 232/RS 485 interface, while the single-axis positioning command module stores up to 3,000 blocks of program code and processes digital servo feedback from the motor to close the position loop.

Protection functions help preserve components during abnormal conditions. An overvoltage trip activates at 475 V on the DC link, and the enclosure carries an IP65 rating so the electronics remain sealed against dust and low-pressure water jets. Current monitoring generates a fault when demand rises to 1.5 x rated current, and thermal supervision issues a warning after 30 s of operation above the internal temperature limit. Additional safeguards include a bleeder warning at 75% of continuous output and an earth-fault threshold of 0.5 × IN, allowing the drive to shut down safely before critical stress is reached.
