Product Description:

The CDB01.1C-ET-ENS-EN2-NNN-NNN-L2-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 supervises motion tasks, communication, and safety logic inside multi-axis automation assemblies. The unit provides command processing for servo amplifiers and converts fieldbus data into drive-local instructions, allowing synchronized positioning, velocity, and torque regulation on production machinery. This makes it suitable for packaging, handling, and conveyor systems that require coordinated axis control from a compact drive platform.

It can coordinate two mechanical axes through its 2-axis configuration. For network connectivity, the control unit carries Multi-Ethernet hardware that exposes two RJ45 sockets operating under the 100Base-TX standard, and this dual-port topology supports line or ring installations without external switches. Internal consumption is limited to 9 W, so thermal load on the host drive remains low. All onboard I/O electronics are energized from a 24 VDC service rail, and they draw 1.1 A during normal operation. When power is first applied, the device admits an inrush of 6 A that lasts up to 60 ms before falling to steady-state demand. The RS-232 service interface supports transfer rates up to 115 kBaud for service access and diagnostics.

The encoder subsystem offers 12 V power for primary feedback devices and a separate 5 V rail for secondary sensors, so both TTL and HTL encoders can be supported without external adapters. Command relays on the board are rated to switch 24 VDC / 1 A, which suits contactor enable and fault signaling circuits. Drive-integrated functional safety is provided through the Safe Torque Off channel, which is routed to a D-Sub 9 safety connector for direct chaining between axes. This layout reduces external safety wiring and keeps the control section integrated with the surrounding drive hardware.
