Product Description:

The DDC01.1-K150A-DA07-00/S001 is a digital intelligent servo drive produced by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It is used in industrial automation lines to energize and regulate synchronous motors, translating control commands into precise torque and velocity while monitoring system status through integrated diagnostics. This arrangement lets the unit handle motion regulation and fault supervision in the same housing, which suits machine-mounted servo applications. Because the power stage and diagnostic functions are integrated, the drive can react quickly to operating changes and protective events during axis motion.

The drive can supply up to 150 A of motor phase current and uses a control supply of 24 V DC at 150 mA. Its command module uses an analog interface for velocity or torque references, while digital servo feedback closes the control loop for stable response during changing loads. Internal components rely on natural convection air cooling, so heat is dissipated without a fan. The housing has an IP65 rating, which blocks dust and low-pressure water jets and supports mounting directly on the machine frame. For status reporting, the unit provides a differential monitor line that swings ±10 V, and a separate 4 mA diagnostic load is used to confirm line integrity. Motor power conductors can reach 75 m without reducing regulation quality, and the standard acoustic class is suitable for equipment that operates close to the machine.

System protection features are keyed to a Ud contact threshold of 200 V; when DC-bus voltage approaches this level, the controller starts a controlled shutdown. Energy in the bleeder resistor is also monitored, and a warning is raised once it reaches 75 % of thermal capacity. Encoder lines can be extended up to 75 m without signal repeaters, which allows feedback wiring to follow long machine paths. The device is intended for installation altitudes up to 1000 m, and the drive is series 1 with version 1. This separation between warning and shutdown functions gives the controller time to report abnormal conditions before a full stop is required.
