Product Description:
The CDB01.1C-SE-ENS-ENS-EN2-NNN-S1-S-NN-FW is a plug-in control section built by Bosch Rexroth Indramat for the CDB Control Units series. It mounts on an IndraDrive power module and forms the command layer that supervises two drive axes within industrial automation lines. The unit interprets encoder feedback, issues setpoint values, and exchanges real-time data with higher-level PLCs so packaging, printing, or assembly equipment can execute coordinated speed, torque, and position routines. Because the control section and power stage are paired in the same drive assembly, command processing and axis hardware remain closely integrated.
Axis monitoring is handled through incremental encoder interfaces labeled ENS for both drive channels, while an additional EN2 port accepts high-resolution feedback from external measuring systems. The analog command path samples input signals at a resolution of 1.23 mV/Inc, enabling fine reference generation, and the integrated DAC can source control voltages up to 5 V / 1 mA for peripheral circuits. When no fieldbus or encoder load is present, the board draws a base demand of 9 W; with all options active, configured consumption rises to 30 W. Internal supply rails for the encoder ports deliver 11.6 VDC at 500 mA to power transducers, and real-time motion commands travel over the SERCOS II fiber-optic interface hosted by the unit. This arrangement lets the module handle reference signals, encoder supply, and optical communication in one control section.
During power-up, the control section tolerates a typical inrush of 6 A that can last up to 60 ms before settling to steady-state draw. The SERCOS transceiver supports data rates as high as 16 MBaud, allowing dense parameter sets and synchronous cycle times across multiple drives. Integrated Safety on Board functions carry the S1 designation and use dual-channel terminals that accept logic at 24 VDC / 3 mA and switch safety outputs rated for 24 VDC / 0.5 A. These circuits permit safe torque off and speed monitoring without external relays.
