Product Description:

The DDC01.2-N100A-DL40-01-FW is a digital intelligent servo drive from Bosch Rexroth Indramat in the DDC Digital Intelligent Servo Drives series. A built-in command module executes single-axis positioning, and rotor position is captured through digital servo feedback. This arrangement allows the drive to manage motion functions directly within the unit. The drive weighs 22 kg, uses standard cooling, and operates from a three-phase 230 V AC mains line. The type designation includes hardware series 1, version 2, and function code 01. Noise emission is rated as standard for the 100 A to 200 A class.

Under steady load, the drive supplies a continuous current of 35 A, which lets it deliver a continuous mechanical output of 6 kW to the connected motor. Current is switched at a PWM carrier frequency of 4 kHz, which balances torque ripple with switching losses. For brief accelerations, the power section can rise to a short-term current of 70 A, while the rated and peak current limits are 100 A. Energy returned from decelerating axes is absorbed by the internal bleeder network, and the drive can accept up to 10 kWs of regenerated energy before external dissipation is required. With a static power loss of 500 W, the unit should be mounted where cabinet airflow can remove the generated heat.

The power interface is designed for plant grids that can provide 18 kVA. Because dynamic braking energy is routed to an internal resistor, the bleeder can dissipate 0.25 kW continuously and reach 20 kW in short bursts, protecting the DC link from overvoltage during rapid deceleration. The enclosure meets the IP65 protection class, so the drive may be mounted outside a cabinet when the machine layout requires decentralized control. These values should be considered when selecting supply protection, wiring, and braking duty.
