Product Description:
Bosch Rexroth Indramat designs the CDB01.1C-ET-EN1-EN1-NNN-NNN-NN-S-NN-FW control card for modular drive assemblies in the CDB Control Units series. Installed in a power section, it forms the supervisory layer that links servo amplifiers, field sensors, and higher-level PLC networks. Within automated machinery it interprets process values, issues real-time motion commands, and maintains coordinated feedback so axes follow programmed trajectories without interruption.
The board protects sensitive transducers with an analog input impedance of 160 kOhm. Its single analog output can source up to 1 mA across a calibrated span of 5 V, allowing it to deliver reference levels to external regulators. Discrete control is standardized on 24 V logic; at this potential the unit monitors 22 digital inputs for limit, home, or emergency signals. Four transistor outputs switch loads of 0.5 A each, enabling contactor drive or lamp annunciation. The card’s control electronics draw 9 W, keeping enclosure heating modest, while the analog and digital channels share a common ground structure to reduce noise.
Fieldbus traffic is exchanged over Multi-Ethernet, permitting EtherCAT, PROFINET, or Ethernet/IP selection without hardware change. Two EN1 interface slots add a thermal load of 6 W each, and the ET communication core requires 2.2 W. Motion feedback enters through 2 x HSF/Resolver ports; the board supplies 8 V DC for HSF sensors and 18.2 Vpp AC for resolver excitation. Start-up is characterized by an inrush of 6 A limited to a 60 ms pulse, preventing breaker trips. With 22 inputs, 4 outputs, and dedicated supplies for each encoder type, the card integrates high-density I/O while holding total section power to 9 W plus auxiliaries.
