Product Description:

The CDB01.1C-SE-EN1-EN2-ENS-NNN-NN-S-NN-FW is a control unit built by Bosch Rexroth Indramat for the CDB Control Units series. Installed on an IndraDrive power module, the board supplies the computational core that manages servo regulation loops and local I/O for compact multi-axis machinery. By accepting encoder feedback and exchanging telegrams with the plant PLC, it enables coordinated motion and diagnostic reporting inside automated assembly lines, packaging cells, and handling gantries. Its selectable encoder slots support incremental or absolute feedback devices, letting OEMs match sensor technology to the application’s accuracy requirements.

This SE variant governs 2 axes through one analog input and one analog output channel, allowing one process variable to be read and one command value to be generated in each cycle. Baseline power draw from the power section is only 9 W, reducing cabinet heat while leaving headroom for additional option cards. Network communication is handled with the deterministic Sercos II bus, so cyclic data and drive profiles transfer with precise timing. For machine-level interlocks, the controller offers 18 dedicated digital inputs and another 4 points that can be configured as inputs or outputs. These resources support homing sensors, limit switches, and status lamps without external expansion.

Feedback wiring is organized through slots X4.1, X4.2, and X8.1, which accept EN1, EN2, and ENS encoder modules. The EN1 module draws only 6 W, so adding high-resolution feedback has minimal impact on the supply budget. EN2 can process incremental signals up to 500 kHz, while the ENS TTL path handles reference mark streams at up to 400 kHz, which helps maintain accurate interpolation at maximum motor speed. A form-C relay rated at DC 24 V, 1 A is provided for ready or fault signaling to external safety circuits. A built-in RS232 port also supports parameter backup and local service access.
