The DDC Digital Intelligent Servo Drives from Bosch Rexroth Indramat comprise compact digital AC servo drive controllers built for high-dynamic, precision motion using fully digital control, monitoring, parameterization, and diagnostics based on high-resolution rotor position measurement across the entire speed range.
The series is offered in an IP65 protection design so the drive can be mounted directly at the machine/feeder area, reducing long motor power and feedback runs that are more susceptible to electrical interference and faults. Each DDC basic unit integrates key power functions such as an internal DC-bus stage, braking energy handling via an internal bleeder/dynamic braking concept, an integrated mains contactor for power isolation, and an internal supply for required control voltages. Functionality is modular through plug-in slots that accept a command interface card (for example SERCOS or analog interfaces, and positioning options depending on configuration), optional auxiliary I/O/measurement modules, and a removable software module that retains the operating firmware and parameter set for fast replacement without re-tuning. The drive also supports integrated motor holding-brake control/monitoring, programmable fault reactions, and local diagnostic indication to simplify commissioning and service in industrial machines.
