Product Description:

The DDC01.2-F100A-D is a servo drive module produced by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. Acting as the power interface between a motion controller and an Indramat servo motor, the unit converts incoming three-phase mains into a regulated DC link and modulates that energy into controlled output phases for precise speed, position, and torque loops in automated machines. It is intended for applications that require stable closed-loop motion control during continuous industrial operation.

This drive supplies a continuous phase current of 100 A, allowing it to run medium-frame motors at their rated torque without thermal derating. The power stage supports a continuous mechanical load of 6 kW, and its insulated-gate transistors switch at a carrier frequency of 4 kHz to keep motor current ripple within servo feedback tolerances. Excess DC-bus energy is bled through an internal resistor that can dissipate 0.25 kW continuously and tolerate bursts up to 20 kW during rapid deceleration. Liquid cooling circulates through the heat sink to stabilize semiconductor junction temperature, while the digital servo feedback channel provides position data for closed-loop control. Noise emission is rated as Standard (100 A to 200 A), matching typical plant acoustic limits.

The power electronics withstand line surges to 745 V and remain sealed against dust and low-pressure water jets under the IP65 housing classification. Plant services must furnish 18 kVA of apparent power at installation, and the converter can deliver a usable mechanical peak of 17 kW for acceleration events before reverting to its 12 kW short-term limit. Regenerated energy up to 10 kWs is routed to the bleeder without tripping the Ud contact threshold of 200 V. Operation is specified up to 25 g/m³ absolute humidity and 1,000 m elevation; above these values, additional derating is required. The drive is Series 1 and Version 2.
