Product Description:

The DDC01.1-K050A-DL05-00 is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. Serving as a combined power amplifier and motion controller, it interfaces with synchronous motors to execute closed-loop position control on assembly lines, packaging equipment, and material-handling axes. By translating low-level motion commands into regulated three-phase currents, the unit keeps a single mechanical axis aligned with the programmed path during repeated production cycles and supports consistent torque, speed, and position control.

At the logic level, the drive is supplied with 24 V DC control power and draws only 150 mA, which keeps the control electronics energized during standby. The power stage delivers a continuous motor current of 50 A, while the ready contact can switch auxiliary devices at 24 V DC / 1 A. Cooling is done by natural convection, eliminating fans but requiring free airflow around the finned housing. An ingress protection rating of IP 65 permits mounting directly on machinery without extra enclosures. A programming link supports a cable length of up to 30 m through the 15-pin D-Sub port, the noise emission category is standard, and digital servo feedback from the motor closes the speed and position loops. The unit uses Function Code 05 and is Series 1, Version 1.

For installation, a minimum clearance of 300 mm must be maintained above the heat sink so natural draft remains unobstructed. The serial channel operates on the V24/RS-232C standard, allowing a host computer to upload parameters or capture diagnostics without proprietary interfaces. At power-up, the drive issues a 100 ms impulse to pre-charge the intermediate circuit before normal operation begins. DC-link supervision then compares the voltage to the 200 V Ud threshold to detect mains loss or regenerative overvoltage, helping the drive react to abnormal supply conditions.
