Product Description:

The DDC01.2-N200A-DS68-00-FW is a servo drive produced by Bosch Rexroth Indramat as part of the DDC Digital Intelligent Servo Drives series. It is designed to regulate synchronous or induction motors in automated machinery. The unit converts line power into controlled three-phase output, delivers high dynamic current, and processes real-time feedback to close the velocity or position loop within a motion axis.

This drive draws a maximum apparent power of 22.5 kVA and delivers a rated output current of 200 A to the connected motor, supporting a continuous mechanical load of 7.5 kW during sustained operation. Its pulse-width modulation runs at 4 kHz, a switching speed that balances current ripple with semiconductor losses of 500 W under nominal conditions. Braking energy is absorbed by an internal bleeder chain that dissipates 0.25 kW continuously and can handle up to 40 kW during short deceleration peaks, which helps manage regenerated energy during rapid slowdowns. Control electronics are powered by a 24 VDC supply limited to 150 mA, separating low-power control operation from the main power stage. Acoustic output is standard for the 100 A to 200 A rating band, and the unit is Series 1 and Version 2.

In installation, heat is removed through standard cooling airflow while the sealed housing carries an ingress rating of IP65, allowing cabinet-free mounting in typical shop environments. Motion commands and parameter data reach the drive through the SERCOS interface, and digital servo feedback from the motor closes the loop without analog transducers, supporting consistent response during commanded speed and position changes. The energy buffer can absorb up to 20 kWs of regenerated power before the bleeder activates, keeping the DC bus within limits at heights up to 1000 m above sea level during regenerative events.
