Product Description:

The Bosch Rexroth Indramat DDC01.2-N100A-DS04-03-FW belongs to the DDC Digital Intelligent Servo Drives series. This drive combines a power inverter, motion logic, and a regenerative brake stage to control servo motors in automated production lines, pick-and-place stations, and material-handling axes. By linking directly to a centralized motion controller through a SERCOS fiber-optic ring, it converts position commands into precisely timed switching patterns that regulate motor torque and speed while returning excess kinetic energy to the DC link.

The power section supplies a continuous output of 35 A, enabling the axis to deliver 6 kW during steady operation. For short bursts, the current can rise to 70 A, and a momentary peak of 100 A clears shock loads without triggering a fault. When the duty cycle allows, the inverter handles up to 12 kW of short-term mechanical load before thermal limits are reached. These current and power levels let the drive support sustained running, brief overload demand, and fast acceleration without pushing the power stage beyond its thermal range. Digital servo feedback reports rotor position to the integrated regulator for closed-loop positioning.

The enclosure has an IP65 rating, so it can mount on machinery without an extra cabinet while still blocking dust and water jets. This protection level supports installation close to the machine process in areas where washdown or airborne debris may be present. Standard airflow removes 500 W of internal loss and maintains components up to an ambient 55 °C at elevations to 1000 m. The bleeder accepts 20 kW peaks and stores 10 kWs of regenerated energy to prevent DC link overvoltage. A line transformer should provide 18 kVA to supply the converter during acceleration and recovery cycles. The inverter switches at a 4 kHz carrier, which sets switching loss and EMC behavior.
