Product Description:

The DDC01.2-N200A-DS47-00-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. Acting as the link between a machine’s motion controller and its servomotor, the drive converts incoming three-phase power into a regulated pulse-width-modulated output so that precise speed, torque, and position loops can be closed in automated production lines. This arrangement allows the drive to coordinate motor response during indexing, speed changes, and position holding.

To handle demanding axes, the unit supplies a continuous output of 200 A while drawing 22.5 kVA from the power supply, so feeder cables and circuit protection must match this load. Its enclosure is rated at IP65, allowing installation on equipment frames exposed to dust and washdown fluids, and reliable operation is maintained at ambient temperatures up to 55 °C. The inverter carrier frequency is 4 kHz, which balances current ripple and switching losses. Standard cooling relies on ambient airflow, and the drive produces 500 W of heat at maximum load. Internally, the electronics tolerate absolute humidity up to 25 g/m³, acoustic output remains within the normal range for 100 A to 200 A drives, and a phase-to-housing potential of 230 V is used for insulation clearances. The drive is series 1 and version 2.

During braking, the chopper network can absorb peaks of 40 kW and a steady 0.25 kW, while cumulative regenerated energy is limited to 20 kWs before external dissipation is required. Installation altitudes up to 1000 m are permitted without derating, and the DC link withstands nonperiodic surges to 745 V. Axis commands pass through a SERCOS interface module, while rotor position reaches the control loop through digital servo feedback. This combination supports accurate closed-loop operation during acceleration, deceleration, and load changes.
