Product Description:
The CDB01.1C-SE-ENS-EN1-NNN-NNN-NN-S-NN-FW is a modular control unit from the CDB Control Units series produced by Bosch Rexroth Indramat. It mounts in an IndraDrive power section and serves as the local automation interface, translating sensor, encoder, and network signals into drive commands for servo or induction motors. This arrangement lets the drive exchange control data and feedback without separate interface cards for common machine functions. By combining analog, digital, and serial connections on one board, the unit reduces cabinet wiring and supports compact multi-axis machine layouts.
The unit provides an analog input range of ±10 V, allowing symmetrical process signals such as torque or velocity setpoints to be read directly. Input impedance is rated at 160 kOhm, so high-impedance sources see very little loading. One buffered analog output supplies 5 V, 1 mA for tasks such as sending speed feedback to a PLC. The digital terminals are arranged as 4 combined I/O, and each channel can be set as an input or output through parameters. When used as outputs, the channels can supply up to 1.1 A max, which is suitable for contactor coils or indicator lamps without external relays. The same terminals accept a 24 VDC logic supply that powers the digital ports, and the control panel uses the standard layout with membrane keys for drive enable, fault reset, and parameter navigation.
Fieldbus communication with the motion controller runs over a SERCOS interface, while point-to-point diagnostics can be handled through the embedded RS-232 serial port. The X4.1 encoder socket supports IndraDyn or Hiperface sin/cos feedback, and X4.2 accepts HSF or RSF incremental encoders. These encoder connections let the unit work with different feedback formats used in compatible motor systems. Digital outputs are rated at 24 V, 0.5 A, and the control voltage is 24 VDC. Cabinet depth contribution is limited to 103 mm, while the total height is 322.6 mm, which helps the unit fit in low-profile enclosures. The X8.1 and X8.2 slots are not populated, and the board comes without a safety option, so STO or SS1 functions must be handled by external safety control.
