Product Description:

The DDC01.2-N200A-DS46-00-FW is a digital intelligent servo drive produced by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. As a closed-loop controller, it interfaces with rotary or linear servo motors to regulate torque, speed, and position in automated machinery. A SERCOS command module gives the unit deterministic communication with higher-level motion controllers, while standard cooling and a sealed housing support on-machine installation without a control cabinet.

This model delivers a rated output current of 200 A, allowing it to energize medium-to-large servo motors without external amplifiers. Internal switching devices operate at 4 kHz, so current regulation remains smooth even when the load changes rapidly. The power stage can sustain a continuous output of 7.5 kW, matching the demands of packaging lines, gantry axes, or tool spindles that require steady power delivery. During acceleration peaks, the input supply must provide up to 22.5 kVA, so the incoming power source must be able to support that maximum demand. An enclosure rating of IP65 shields the electronics from dust and low-pressure water jets, permitting mounting close to actuators in washdown or particulate areas. Digital servo feedback from the connected motor supplies real-time position data to the drive control loop, and the noise emission is rated as standard for the 100 A to 200 A class.

Energy absorbed during deceleration is routed to a braking resistor that dissipates 0.25 kW continuously and tolerates bursts up to 40 kW, helping prevent DC-bus overvoltage. If the application cycles faster than the bleeder can handle, as much as 20 kWs of regenerated energy is still accepted without fault. The power section itself loses only 500 W when the bleeder is inactive, which reduces heat buildup around the unit. Installation is permitted up to 1000 m above sea level, and operation can continue at ambient temperatures up to 55 °C with derating when airflow around the heat sink remains unobstructed.
