Product Description:

The DDC01.2-N100A-DL04-01-FW is a digital intelligent servo drive produced by Bosch Rexroth Indramat as part of the DDC Digital Intelligent Servo Drives series. It combines a power stage with closed-loop control functions to govern one motorized axis in automated production lines. The integrated single-axis positioning command module executes motion sequences internally, relieving the PLC of time-critical interpolation tasks. This arrangement lets the device supply regulated current directly to a synchronous servo motor while maintaining accurate speed and position under changing mechanical loads. It is suitable for applications that need repeatable indexing, controlled acceleration, and stable operation during varying load conditions.

Standard cooling removes the 500 W of internal power loss produced at rated load. The drive delivers a continuous output current of 100 A for sustained operation. A bleeder resistor dissipates regenerated energy; it is rated for 0.25 kW continuously and can absorb up to 20 kW momentarily, protecting the DC link when loads decelerate. Noise emission is rated as standard for 100 A to 200 A devices, and the PWM stage switches at 4 kHz. Positioning profiles rely on digital servo feedback sent directly to the internal controller, and the control parameters use function code 04 and version 01.

In installation, the drive draws up to 18 kVA from the supply, which helps size upstream contactors and cables. During deceleration events, it can return as much as 10 kWs to the bleeder circuit, reducing stress on the mains transformer. The aluminum housing is sealed to IP65, allowing direct mounting on moving machine axes without an additional enclosure. This enclosure helps protect internal components from dust and low-pressure water spray in normal industrial service. The unit weighs 22 kg, which helps limit added mass on gantry or arm assemblies.
