Product Description:

The DDC01.2-N100A-DL09-01-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat as part of the DDC Digital Intelligent Servo Drives series. It combines power conversion with motion control, delivering regulated three-phase output while its single-axis positioning command module executes trajectory commands sent from a higher-level PLC. Deployed on material-handling lines, pick-and-place gantries, and packaging stations, the drive governs motor torque, speed, and position through digital servo feedback so that each axis repeats programmed movements precisely. Because the positioning module is integrated into the drive, command processing and current control occur in one unit, which helps the axis respond quickly to changing motion commands.

This controller supplies a rated motor current of 100 A and requires up to 18 kVA from the mains, so cabinet breakers and wiring must be sized accordingly. Internal IGBTs switch at 4 kHz, and this pulse-width modulation rate balances smooth motor current with acceptable switching losses in the power stage. An enclosure classification of IP65 seals the housing against dust ingress and high-pressure water jets, allowing direct machine-side mounting in areas that are exposed to washdown or airborne debris. Regenerative energy is routed to an integrated bleeder resistor that dissipates 0.25 kW continuously and up to 20 kW during rapid deceleration events, preventing DC-bus overvoltage. Standard cooling draws ambient air across the heat sink, and typical acoustic output falls in the manufacturer’s standard noise range for drives in this current class.

The power section can deliver a mechanical peak load of 17 kW, while normal operation is limited to 6 kW continuous and 12 kW short-term to protect the motor and drive during sustained duty. During braking sequences, the energy absorber can store and convert up to 10 kWs before thermal limits are reached. Overall conversion inefficiencies appear as about 500 W of heat, which must be removed by cabinet airflow to keep internal temperatures within an acceptable range. Frequent acceleration and deceleration cycles can increase the thermal burden on the enclosure because both conversion losses and braking losses add heat to the surrounding air. The unit uses function code version 01 and hardware version 2 for this configuration.
