Product Description:
The CDB01.1C-ET-ENS-ENS-EN2-EN2-S2-S-NN-FW is a modular drive control unit manufactured by Bosch Rexroth Indramat and supplied in the CDB Control Units series. It plugs onto compatible power sections to form a complete servo amplifier. In industrial automation, its task is to execute motion commands, process feedback from primary and secondary encoders, and forward status data to higher-level PLCs over Ethernet networks. By combining motion control, feedback handling, and network communication in one plug-on unit, it reduces the need for separate interface modules inside the drive assembly.
A logic supply of 24 V DC powers the internal processors, LEDs, and signal-conditioning circuits. Local machine states reach the controller through 18 digital inputs, while actuator commands can be issued with 2 analog outputs that are factory scaled for ±10 V. One process variable may also be sensed as a voltage or current on the single 1 analog input. Physical network access is provided by 2 x RJ-45 (8-pin) sockets on the front panel, and these are internally routed through a managed switch so drive-to-drive daisy-chaining does not require external hubs. The front connection layout also keeps control wiring accessible when the unit is mounted on the power section.
Application flexibility is expanded by 4 configurable digital I/O points that can each be set as either sourcing or sinking, depending on the parameter setting. The integrated switch supports full-duplex communication at 100Base-TX speeds. Protocol handling is managed by the controller’s Multi-Ethernet communication layer, so EtherNet/IP, PROFINET, and EtherCAT devices can use the same hardware. For machines that require certified stopping and monitored speed reduction, the board carries the Safe Motion (SIL2 / Cat.3 PL d) option. Safety channels are wired through dedicated terminals and do not load the main CPU, and the configurable I/O can be assigned to interlocks, reference switches, or simple status exchange with nearby devices.
