Product Description:

The DDC01.2-N050C-DS68-00-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It combines a power inverter and motion controller in one enclosure so it can supply regulated torque and speed commands to synchronous motors used in automated machinery. The unit belongs to the product group of digital intelligent servo drives and supports decentralized installation, letting designers place the drive directly on moving axes or wet zones without a control-cabinet barrier.

The drive carries a protection rating of IP65 and uses standard cooling fins to dissipate the 500 W of internal power loss. System coordination takes place over a SERCOS interface command module, while rotor position is returned through digital servo feedback. Under continuous duty it delivers 25 A of current, producing a mechanical output of 4 kW and permitting a continuous bleeder load of 0.25 kW on the DC link. Pulse-width modulation is generated at 8 kHz, which works with the “standard (50 A) reduced-noise” listing to limit acoustic output. The housing weighs 21 kg, can be mounted up to 1 000 m above sea level, withstands short-term mechanical demand of 8 kW, and is identified as series 1, version 2.

A peak bleeder capacity of 10 kW and a maximum mechanical ceiling of 8.5 kW cover energy surges during fast deceleration or indexing. Both the rated current and the 50 A peak current share the same numerical limit, allowing the DC bus to absorb up to 5 kWs of regenerated energy. The incoming supply must furnish 6 kVA, so upstream protection devices are sized to that draw. Firmware is ordered separately to match the application, and standard cooling, reduced noise emission, and a 21 kg mass let the unit handle continuous, short-term, and peak profiles without violating electrical or thermal margins.
