Product Description:
The CDB01.1C-SE-EN2-EN2-EN2-EN2-S2-S-NN-FW belongs to the CDB Control Units series manufactured by Bosch Rexroth Indramat. As a plug-in control section for IndraDrive power modules, it coordinates servo axes, handles feedback signals, and exchanges data with higher-level controllers inside industrial automation cells. This model provides the signal conditioning, cycle timing, and safe-motion interfaces required for motion sequences that demand synchronized position and velocity loops. Because it plugs directly into the drive platform rather than operating as a standalone controller, it keeps axis control and feedback processing close to the power section.
The unit’s analog output path completes a conversion in 10 µs. This response time shows how quickly a drive command can be reconstructed as a voltage at the terminal. Each increment is quantized at 19.5 mV/inc, which is the smallest step that can be issued to analog-controlled components. Closed-loop torque or current regulation is refreshed every 125 µs, so the control section can correct disturbances eight thousand times per second. For encoder channels, the board presents 120 Ω of input resistance, which helps prevent signal reflections when long motor cables are used. It can accept differential sine, TTL, or RS-422 feedback up to 1000 kHz without loss of edge integrity or interpolation accuracy.
Total base consumption is 9 W, and the dedicated encoder conditioner adds another 6 W. These values help size the cabinet power supply and account for heat produced by the control section inside the enclosure. The sine encoder track is driven at 1.0 Vpp, while the sensor rails deliver 5.0 V at 350 mA to the transducer head. For real-time networking, the SERCOS interface can close telegram cycles down to 1000 µs, and its optical module draws 2 W. Relay contacts rated at DC 24 V / 1 A provide hardware enable functions, while logic inputs for the safe-motion channel are energized at 24 V and 3 mA. When the STO circuit is triggered, the output stage is limited to 1.6 A, and secondary outputs supply 24 V at 0.5 A for external status indicators.
