Product Description:

The DDC01.2-N150A-DS46-00-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. It operates as a closed-loop power stage that energizes an Indramat synchronous motor while exchanging real-time position data through digital servo feedback. The drive is series 1 and version 2, and it incorporates a SERCOS interface command module so it can receive deterministic motion profiles over fiber-optic cabling. In automated machining centers, pick-and-place stations, and packaging lines, the drive coordinates axis movement and dissipates returned energy through an internal resistor bank.

The power section is rated for a continuous output of 150 A, corresponding to 7.5 kW of mechanical output. During acceleration or impact loads, current may rise to 200 A, allowing short-term delivery of up to 33 kW of mechanical power. A brake resistor can convert 0.25 kW of excess DC-link energy into heat on a continuous basis, which helps prevent overvoltage trips when the load drives the axis. To support this operating range, the mains transformer must provide 22.5 kVA. SERCOS telegrams synchronize with the IGBT inverter, and noise emission is categorized as standard for devices in the 100 A to 200 A range.

Cooling draws enclosure air across the heat sink, where total dissipation reaches 500 W. The cast aluminum housing is rated IP65, so it can be mounted directly on machinery at altitudes up to 1000 m above sea level and in ambient temperatures as high as 55 °C. Pulse-width modulation occurs at 4 kHz, providing a practical balance between control response and switching losses. The DC bus can absorb 20 kWs of regenerated energy per cycle, and the unit has an overall mass of 22 kg. Maximum acoustic output remains within the standard range for this drive class.
