Product Description:

The DDC01.2-N050C-DL04-01-FW digital intelligent servo drive is manufactured by Bosch Rexroth Indramat and belongs to the DDC Digital Intelligent Servo Drives series. Designed for single-axis motion, it combines power electronics with a Single Axis Positioning command module to control servomotor speed and position in automated cells. The digital servo feedback interface closes the control loop with the motor encoder, allowing accurate response during indexing, positioning, and speed-regulated operation. That integrated layout keeps the motion functions close to the motor connection and reduces the need for separate external control hardware at the axis. Standard cooling and reduced-noise operation also allow the unit to be mounted directly on machinery without requiring a separate cabinet.

The drive has a rated output of 50 A, which is the continuous current available to the motor windings. It can support a mechanical load of 4 kW without derating, and the input side must supply 6 kVA for this operating point. Internally, pulse-width modulation runs at 8 kHz, which helps reduce torque ripple at the shaft. The enclosure is rated IP65, so dust and water jets do not affect the electronics. Continuous bleeder power is 0.25 kW, and power loss is 500 W, so heat removal must be considered where the drive is installed. Noise emission is listed as standard reduced for the 50 A class, which supports use on machinery where lower audible output is preferred.

During dynamic stops, the bleeder can absorb a peak of 10 kW, and the capacitor bank can accept 5 kWs of regenerated energy to protect the DC link. Local memory can store up to 3000 program blocks, which reduces the amount of positioning traffic that has to come from the higher-level control and supports repeated motion sequences inside the drive. The unit remains thermally stable in ambient temperatures up to 55 °C and at installation altitudes up to 1000 m when convection paths are kept clear. A transport mass of 21 kg supports stable mounting on machine frames and gantries. The product is Series 1, Version 2, with Function Code 04 and Version 01.
