Product Description:

The DDC01.2-N200A-DL30-01-FW is a servo drive unit produced by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It combines a power stage with a single-axis positioning command module, allowing it to regulate compatible synchronous or asynchronous servo motors in automated machinery. Within a machine, the drive converts incoming three-phase mains power into controlled motor output and processes feedback signals for accurate motion control. Because the positioning module is built in, the unit can handle axis commands without a separate external positioning card. It is intended for automated equipment that requires repeatable starts, stops, and speed changes.

The power stage is rated for 200 A of continuous output current, allowing the unit to supply large-frame motors during sustained operation. It accepts a mains input of 3x220/230 V AC and draws up to 22.5 kVA at full load. Internal transistors switch at 4 kHz, which balances output waveform control with manageable switching losses. Under steady duty, the converter can support a mechanical output of 7.5 kW. Regenerated energy of up to 20 kWs is directed to an integrated bleeder circuit with 0.25 kW of continuous dissipation. This electrical capacity suits applications that require high continuous torque from the connected motor.

For short production surges, the drive tolerates a mechanical output of 33 kW, and its bleeder can momentarily absorb 40 kW during rapid deceleration. The enclosure has an IP65 rating, which protects the internal electronics from dust and low-pressure water jets. Normal operation is specified within an ambient range of +5 to +45 °C, and derating is recommended above that range up to the stated upper limit of +55 °C. Air cooling removes heat from the heat sink, so the installation must allow a clear airflow path around the unit. The single-axis positioning module works with digital servo feedback for accurate axis control.
