Product Description:

The DDC01.1-F050A-DS22-02-FW is a servo drive manufactured by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. It houses a three-phase inverter, regenerative dissipation stage, motion firmware, and diagnostic interface in one IP-rated enclosure. In automated machinery the unit converts controller setpoints into regulated motor current, maintaining commanded speed and position on packaging lines, handling robots, and material transfer axes. Its stand-alone construction lets machine builders mount it directly on the mechanical frame, minimizing cabinet space.

Electrical compatibility starts with a supply of 3x 220 V AC, and the electronics remain stable when that voltage drifts by +15%/-10%. The control loops synchronize to network frequencies up to 60 Hz, so the same drive type supports plants running either 50 or 60 hertz utilities. During continuous operation the inverter delivers 25 A of average motor current; when the mechanical load peaks, line demand can rise to 6 kVA. A pulse-width-modulation carrier at 8 kHz switches the IGBTs quickly enough to limit motor audible noise while preserving current resolution. Together these ratings allow the device to propel mid-frame servo motors without overstressing supply transformers or upstream protection.

For short accelerations the power stage can source 50 A, after which the excess kinetic energy is routed to an internal bleeder that dissipates 0.25 kW continuously and admits surges to 10 kW. The intermediate circuit can store up to 5 kWs, preventing DC-bus overvoltage during rapid deceleration. Operating losses reach 500 W at maximum load when the bleeder is inactive, and safe thermal margins are sustained between +5 °C and +45 °C ambient. The die-cast housing carries an IP65 rating, blocking dust and low-pressure water jets, and its 21 kg mass permits direct machine mounting without supplementary enclosures or vibration dampers.
