Product Description:

The DDC01.1-K050A-DS40-02-FW is a digital intelligent servo drive from Bosch Rexroth Indramat in the DDC Digital Intelligent Servo Drives series. It conditions power for synchronous and asynchronous servomotors and performs closed-loop control for coordinated positioning, indexing, and velocity regulation in industrial automation. In operation, it converts incoming electrical power into controlled motor output so a connected axis can follow motion commands with stable speed and torque response. That operating behavior suits applications that need controlled acceleration, deceleration, and repeatable stopping. The unit accepts a three-line mains connection at terminal X7, while machine signals enter through X8.

The drive is designed for 3-phase AC operation, and natural convection cools the electronics without external fans. Through connector X5, it supplies the motor with up to 50 A of continuous output while rotor position is measured through Digital Servo Feedback at X4. This feedback path lets the controller correct position and maintain consistent response as load conditions change. Motion commands are transmitted through the SERCOS interface command module for synchronized communication with higher-level control. An internal DC-bus monitor trips at 475 V to protect the power stage, and the cast housing carries an IP65 rating for use in areas exposed to dust or low-pressure washdown.

The control card is Series 1, Version 1, and the unit accepts up to 5 plug-in modules for optional I/O or communication expansion. Service access is available through RS-232 (X2), and the drive also provides analog diagnostic outputs for external monitoring. Those outputs can be used to observe operating values with external measuring equipment during setup or routine service. A low-voltage DC-bus threshold of 200 V stops drive pulses when bus voltage falls below the limit. Its standard noise class falls within the 100 A to 200 A range, matching ordinary industrial acoustic expectations.
