Product Description:

The DDC01.1-K100A-DL05-01-FW drive is manufactured by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. It serves as the regulated power stage between a three-phase supply and an Indramat servomotor in industrial positioning or process lines. In operation, the unit converts incoming electrical power into controlled motor current so the connected axis can follow commanded speed and position changes. This type of drive is suited to automated equipment that requires stable servo response, repeatable motion, and direct integration with Indramat motor and feedback components.

The power section is fed through 3 x AC 220/230 V mains terminals and is synchronized with a 50/60 Hz line supply. Under continuous duty, the drive delivers a nominal bus output of 100 A, while a protection circuit trips at 1.5 × rated current to guard against short-term overloads. Overvoltage shutdown engages above 475 V on the DC link to reduce stress on internal components. Motor leads connect to the output connector and receive the correct phase sequence without additional transposition. This arrangement supports consistent power delivery to the servomotor while protecting the drive during abnormal electrical conditions.

The control side is equipped with a Single Axis Positioning command module that interprets NC instructions and closes position loops with digital servo feedback. Cooling is provided by natural convection air cooling, so cabinet airflow must remain unobstructed during operation. For applications that use a motor brake, the drive provides a 24 V DC release output that can be wired directly to the brake coil. The feedback path allows the controller to monitor actual motor movement in real time, which improves tracking accuracy. The integrated brake release output simplifies wiring for axes that need controlled brake actuation during motion and stopping.
