Rexroth CDB02
Product Name
Bosch Rexroth CDB02 IndraDrive double-axis BASIC control section.
Product Introduction
CDB02 is a control section for IndraDrive double-axis servo systems. It executes motion control, communication, encoder evaluation, and safety functions, and mates with a compatible IndraDrive power section to form a complete servo axis package.
Detailed content
Technical Specifications
Type code defines communication, encoder, and safety configuration. CDB02.1B supports Multi-Ethernet communication, including Sercos, EtherCAT, PROFINET IO, and EtherNet/IP depending on firmware and ordering option. Encoder interfaces support IndraDrive multi-encoder types for axis 1 and axis 2. Safety options include STO, Safe Motion, and Safe Motion Bus depending on interface code. Control panel interface and firmware are ordered separately for many versions. Typical control-unit ambient rating is 0 to 55°C.
Function Features
Double-axis coordinated motion, multi-protocol Ethernet master or slave communication, multi-encoder feedback, integrated safety, parameter storage through memory module or firmware media, and diagnostic LEDs.
Application Scenarios
Multi-axis machine tools, printing presses, converting lines, packaging machines, robotics auxiliaries, and industrial servo retrofits requiring centralized double-axis control.
Performance Parameters
Performance depends on firmware, motor type, encoder resolution, and power-section rating. Deterministic motion cycles are achieved through the selected real-time Ethernet or Sercos communication interface.
Material Composition
Industrial control printed-circuit assembly in a molded connector front plate. Housing materials are flame-retardant thermoplastic and metal shielding components. Connectors use gold- or tin-plated contacts according to signal class.
Structure Features
Modular control section with front communication, encoder, safety, I/O, and control-panel connectors. The unit inserts into the corresponding IndraDrive power section backplane. Optional analog and digital I/O connectors, CANopen interface, and safety terminals are provided according to type code.
Working Principle
The control section receives setpoints from the higher-level controller and feedback from encoder interfaces. It calculates current, speed, and position control loops, then commands the power section. Safety circuits monitor STO or extended safe-motion conditions and remove torque or limit motion according to the configured safety function.
Installation Requirements
Install only with the Rexroth power section specified by the full CDB02 type code. Match firmware to motor and safety configuration. Use proper grounding and shielded encoder and communication cables. Insert the control section without forcing the backplane connectors.
Usage Notes
Back up drive parameters before replacement. Firmware must match the application profile. Verify encoder shielding, safety jumper settings, and communication node configuration prior to energizing. Do not mix incompatible safety option codes.
