Product Description:

Bosch Rexroth Indramat manufactures the DDC01.2-N200A-DA02-01-FW as part of the DDC Digital Intelligent Servo Drives series. The unit combines a power section with an analog interface command module to control synchronous motors in positioning or speed-regulated industrial axes. This arrangement keeps the power stage and command interface in one housing, which suits compact servo systems with limited cabinet space. Within an automation cabinet, it supplies regulated current to the connected motor while coordinating motion through digital servo feedback, allowing tight loop control without external converters.

The drive is sealed to IP65, which helps protect the electronics from dust and low-pressure water jets. A supply network capable of 22.5 kVA must be available because the converter can draw that apparent power under rated load. This capacity supports the drive when the motor is operated near rated demand. During acceleration or rapid torque changes, it delivers up to 200 A of peak output current. Its continuous output is rated at 7.5 kW. Current is switched at 4 kHz, a frequency that balances smooth motor operation with manageable semiconductor losses. Cooling relies on ambient airflow across the housing, and a bleeder circuit continuously dissipates 0.25 kW so regenerated energy from the motor does not overcharge the DC link.

The electronics can operate at ambient temperatures up to 55 °C if airflow is unobstructed and total power loss of 500 W is removed from the panel. Regenerative peaks of 20 kWs are absorbed by the internal bleeder resistor, and the short-term current limit of 90 A helps protect the drive from overheating during those events. Operation is permitted where absolute moisture stays below 25 g/m³ and relative humidity does not exceed 95 %, provided condensation is avoided. The condensation-free condition is important because moisture on energized components can disturb control operation. At elevations above 1000 m, derating may be required, and noise emission is in the standard 100 A to 200 A class.
