Siemens Sinamics CCB 10000432.71 / GCB 10000428.00 Power Cell
The Siemens Sinamics CCB 10000432.71 and GCB 10000428.00 are power cell modules designed for use in Siemens' harmonic drive systems, commonly deployed in high‑performance multi‑axis servo applications. These units serve as the DC‑bus power supply and energy storage elements for the Sinamics drive family, ensuring stable voltage levels for connected motor modules. They are integral components in applications such as robotics, packaging machinery, and machine tools where compactness and reliability are paramount.
The CCB (Central Capacitor Bank) 10000432.71 provides buffering of the DC link, reducing voltage ripple and supplying peak current during acceleration. The GCB (Grounding and Control Board) 10000428.00 handles monitoring, diagnostic, and safety functions. Together, they form a robust power distribution system that enhances drive performance and protects against electrical faults.

Comprehensive diagnostics: The GCB reports DC link health and fault status to the drive controller, enabling predictive maintenance.
Redundancy-ready: Two power cells can be paralleled for higher power or N+1 redundancy.
Typical Applications
Industrial robotics: Providing stable power for multiple servo axes in a single cabinet.
High‑speed packaging lines: Supporting dynamic acceleration of servo‑driven cutters and feeders.
CNC machine tools: Powering spindle and feed drives with consistent voltage.
Printing presses: Ensuring tension control in multi‑motor configurations.
Installation and Integration
Mount both modules on a common mounting plate inside the drive cabinet. Connect the DC link terminals of the CCB to the Sinamics motor modules, and wire the GCB’s monitoring outputs to the PLC inputs for system supervision. Ensure proper grounding per Siemens installation guidelines. The modules are fanless and rely on convection cooling, so maintain adequate spacing.
Compliance
Both modules are CE marked and RoHS compliant. They meet EMC directive requirements when installed in a shielded cabinet with proper filtering.
Conclusion
The Siemens Sinamics CCB 10000432.71 and GCB 10000428.00 power cell modules provide a reliable, high‑performance DC bus solution for modern servo drives. Their compact design and integrated safety/monitoring features ensure optimal machine productivity and protection.
