Product Description:

The DDC01.2-N100A-DS69-00-FW is a digital intelligent servo drive produced by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. Serving as the central power amplifier and motion controller for SERCOS-linked axes, it interprets high-speed command words and feeds matched current to the attached motor. By combining position feedback with current vector control, the unit enables closed-loop speed and torque regulation required for precise industrial automation. This arrangement supports coordinated axis response in packaging, handling, and machine-tool applications where stable feedback processing is important.

The drive’s thermal design supports a continuous current of 35 A, translating to a mechanical output capacity of 6 kW when paired with compatible motors. Pulse-width modulation is generated at 4 kHz, which affects current ripple and acoustic behavior during operation. To operate, the converter draws up to 18 kVA from the supply, and its enclosure carries an IP65 rating so it can be mounted directly on a machine frame without a cabinet. Commanding is handled through the SERCOS interface, and rotor position is read through digital servo feedback. Standard cooling dissipates 500 W of power loss, and direct machine mounting can reduce the need for a separate enclosure in installations where protected surface mounting is preferred.

Dynamic braking is handled by an integrated bleeder that converts regenerated DC-bus energy into heat. It can absorb 0.25 kW continuously during steady deceleration and up to 20 kW for short peaks, provided that the total event energy does not exceed 10 kWs. This protects the DC link when high-inertia loads stop abruptly and helps manage returned energy during repeated braking cycles. The drive housing weighs 22 kg, which is relevant for panel or arm mounting near the motor. The unit is series 1 and version 2.
