Product Description:

The DDC01.1-K100A-DG01-00 is a digital servo drive produced by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. It serves as the axis amplifier between the main supply and a compatible servo motor, regulating armature current and supporting closed-loop position control in automated machinery. In automated equipment, this arrangement lets the drive manage torque, speed, and axis response from a higher-level control system. The unit is Series 1 and Version 1.

The drive accepts a three-phase supply of 3 × AC 230 V, so it can connect directly to standard low-voltage industrial distribution. It provides a rated output of 100 A, which supports mid-frame Indramat motors that require sustained current during acceleration and load changes. Internal current sensing monitors output demand so the power stage can maintain regulated motor current as load conditions vary. Cooling is handled by natural convection air cooling, so the installation must allow vertical airflow instead of relying on an added blower. Function code 01 corresponds to the DG01 option set, and serial diagnostics and parameter transfer are available through the integrated RS-232 port. Protective circuitry responds when the intermediate circuit rises above 475 V and when the mains drop below 200 V, helping prevent unstable operation.

During startup, the logic boards receive an enable signal only after a 100 ms power-on pulse, which filters out short interruptions. The control electronics use a +24 V load rail, and the analog section is checked at +15 V while a negative 15 V rail supports differential verification. This control supply arrangement supports the internal logic and analog monitoring circuits used by the drive. Standard noise emission for the 100 A to 200 A class keeps operation within typical plant sound levels. Digital servo feedback from the connected motor closes the loop for precise position control without requiring an external encoder.
