Product Description:

The DDC01.2-N050A-DS01-02-FW digital intelligent servo drive is produced by Bosch Rexroth Indramat as a member of the DDC Digital Intelligent Servo Drives series. The unit functions as a closed-loop power stage that converts mains energy into regulated three-phase output for synchronous or induction motors in automated machinery. Within an automation cell, it coordinates motion commands, monitors load conditions, and dissipates regenerated energy so axes can decelerate safely.

For continuous duty, the drive supplies a mechanical output of 4 kW, while short-term demand can be sustained at 8 kW and momentary peaks can reach 8.5 kW. Regenerative energy is routed to an internal bleeder rated at 0.25 kW continuously and 10 kW for braking surges, keeping the DC bus within limits. The output stage delivers a nominal current of 50 A, a figure that guides conductor sizing and thermal design. Internal dissipation reaches 500 W during rated operation, and the noise emission is standard. Motor position data is evaluated through digital servo feedback, allowing the control loop to respond quickly to changing load conditions.

The command module incorporates a SERCOS interface, so setpoints and status data travel over fiber without additional cabling. Pulse-width modulation is generated at 8 kHz, and the electronics can operate in ambient temperatures up to 55 °C under standard cooling. Plant infrastructure must deliver 6 kVA of apparent power, and the IP65 enclosure enables installation outside a control cabinet. The unit carries function code 01 and is series 1, version 2. The drive can absorb 5 kWs of regenerated energy through its bleeder circuit, and its 21 kg mass supports direct machine mounting while cooling fans maintain airflow across the heat sink.
