Product Description:

The CDB01.1C-SE-ENS-EN1-NNN-NNN-L1-S-NN-FW is a control unit manufactured by Bosch Rexroth Indramat for the CDB Control Units series. It plugs into an IndraDrive power section and supervises command processing, feedback evaluation, and integrated safety for multi-axis automation cells. By combining fieldbus communication with direct encoder handling, the device coordinates motion sequences, monitors limit conditions, and issues stop commands during fault conditions. This arrangement keeps motion control, feedback processing, and safety-related functions within the same drive platform.

This model controls 2 axes and draws a base control power of 9 W, so cabinet heat from the electronics remains low. Parameter exchange with the drive system occurs over the SERCOS fiber-optic interface, enabling deterministic cycle times for synchronized motion tasks. Its transistor outputs can source up to 500 mA, providing drive-ready signals to external relays or contactors. The EN1 analog-to-digital converter resolves position data with 12-bit resolution, supporting mid-range feedback accuracy for servo positioning. Encoder Interface 1 accepts IndraDyn, HIPERFACE, or 1 Vpp sinusoidal encoders, while Encoder Interface 2 is prepared for resolver or HSF transducers, so the controller can handle mixed feedback types in one drive assembly.

The EN1 feedback channel is powered from 8 VDC, and a separate ENS supply delivers 12 V for secondary encoder electronics. Safety acknowledgment inputs use an L1 circuit rated at 24 VDC / 1 A, while logic commands enter through a 24 V, 3 mA control line. Output pulses can be stretched to 60 ms, and internal relay contacts provide status reporting for external control circuits. The integrated starting lockout provides the drive's safety function, and an emergency stop in Safety Stop Category 0 removes torque without delay. During power-up, the unit withstands an inrush current of 6 A, which is relevant for fuse and control-supply selection in the cabinet.
