Product Description:
Bosch Rexroth Indramat manufactures the CDB01.1C-SE-EN1-EN1-EN2-EN2-S2-S-NN-FW. This unit belongs to the CDB Control Units series and functions as a modular drive controller subsystem for IndraDrive installations. Within an automation rack, it handles logic processing, I/O routing, and sensor interfacing so the associated power section can regulate motor torque and speed. By combining control functions with selectable encoder channels, the board supports motion tasks such as positioning, conveyor synchronization, and packaging line indexing across multi-axis machines. It also provides the communication link between higher-level PLCs and the connected drives.
During operation, the board draws a base power of 9 W and is supplied through a control rail that must deliver 24 V DC. The two differential analog outputs swing up to 5 V full scale, and each incremental step is quantized at 19.5 mV/inc, providing fine voltage references to external drives. Logic inputs recognize an ON state once the line exceeds 15 V, while the eight digital outputs can source up to 500 mA per channel for relay coils or indicator stacks. At startup, the unit presents an inrush demand of 6 A for roughly 60 ms, so the upstream supply must tolerate that brief pulse. These electrical values support stable control signaling and auxiliary output switching in compact drive assemblies.
Encoder channel EN1 excites resolver transducers with a 4 kHz carrier at 18.2 Vpp, while the secondary EN2 channel provides a regulated 5.0 V supply with sense leads and can deliver 350 mA to digital encoders. When several outputs are energized at the same time, the board limits the combined load to 1000 mA, and an integrated safety relay rated for 24 V DC at 1 A provides emergency-stop feedback. Network integration is handled through an engineering port that supports 100Base-TX Ethernet as well as a serial diagnostic interface running at 115 kBaud. These service connections allow setup access and diagnostics without using the real-time fieldbus.
