Product Description:

The DDC01.1-K100A-DL26-00 is a digital intelligent servo drive built by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It interfaces with brushless servo motors through digital servo feedback and executes motion profiles issued by its single-axis positioning command module. Within an automation cell, it converts AC supply power into controlled PWM output to regulate motor torque and velocity, so machine tools or handling systems can follow precise trajectories without an external position controller. This arrangement supports machine tools, transfer systems, and other automated axes that need repeatable speed and position control.

This drive draws a connected load of 18 kVA and sustains a continuous output current of 70 A, which helps size upstream circuit protection. Thermal energy produced during operation is managed by natural convection air cooling, while an internal bleeder dissipates regenerated energy and absorbs up to 0.5 kW continuously and 20 kW in short peaks. Motor acceleration surges can reach a peak current of 100 A, and the switching stage modulates that current at 4 kHz. The drive accepts regenerative returns up to 7 kWs before the bleeder duty cycle is exceeded, and the noise emission is standard for the 100 A to 200 A range. Operation is permitted at relative humidity up to 95 percent, at ambient temperatures up to 55 °C, and at elevations up to 1000 m above sea level. Above those limits, output capability must be reduced. The drive is Series 1 and Version 1.

Mechanical output limits align with its electrical ratings, with continuous shaft power of 12 kW and brief overload capacity up to 17 kW. During braking or idle, internal losses amount to 420 W, and that heat must be removed through cabinet ventilation. The housing carries an IP65 rating, so dust and low-pressure water jets do not compromise the electronics. This enclosure helps protect the drive in machine-mounted installations where airborne contamination or incidental water exposure may occur.
