Product Description:

The DDC01.1-K100A-DG02-00 is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It works with motors that provide digital servo feedback and follows motion commands from numerically controlled equipment in closed-loop operation. This allows the drive to regulate torque, speed, and position for automated axes that require repeatable response during indexing, contouring, and synchronized machine movement. The unit is identified within the platform as Series 1, Version 1, with Function Code 02.

This model delivers a rated output current of 100 A, allowing it to power medium-capacity synchronous motors without external amplification. Continuous output reaches 12 kW, while short-term output can rise to 17 kW during acceleration or rapid indexing. A facility supply of 18 kVA is required so the drive can meet peak demand, and the output is modulated by a PWM carrier of 4 kHz to support smooth motor control. Under nominal load, the unit dissipates heat through its air-cooled enclosure without requiring forced ventilation. The noise emission is standard for the 100 A to 200 A rating band, and operation is permitted up to 1000 m above sea level without power derating. Its sealed housing blocks dust and direct water jets, which supports mounting close to the machine rather than inside a separate cabinet.

An internal bleeder resistor continuously absorbs 0.5 kW of regenerated energy and tolerates momentary peaks of 20 kW during abrupt stops. The energy limit is 7 kWs before the controller issues a thermal fault, helping protect the braking circuit during repeated deceleration events. The enclosure has a protection rating of IP65, which permits installation near moving machinery in demanding industrial areas. The basic weight is 22 kg, giving the housing enough mass for stable mounting on vertical panels. This energy-handling arrangement helps keep the DC bus within its operating range when the axis returns power during braking.
