Product Description:

The CDB01.1C-ET-ENS-ENS-NNN-NNN-S2-S-NN-FW is a modular control unit manufactured by Bosch Rexroth Indramat within the CDB Control Units series. Designed as the logic section of an IndraDrive power stage, it coordinates multi-axis motion for packaging, printing, and material-handling cells. By processing feedback from encoders and passing commands over Ethernet-based fieldbuses, the unit directs servo amplifiers so axes follow programmed trajectories with the deterministic timing required in industrial automation.

This configuration supports 2 independent drive axes and provides two standard encoder evaluation channels, allowing position feedback from each motor without additional interface boards. Its base consumption is 9 W, so heat dissipation inside a control cabinet remains low during standby. Communication with higher-level PLCs is carried on a Multi-Ethernet interface, allowing selection of PROFINET, EtherNet/IP, or other 100 Mbit protocols. Each incremental encoder input is filtered at 500 kHz, and TTL reference signals up to 400 kHz are accepted, enabling high-resolution position capture on fast rotary systems. During power-up, the module draws an inrush current of 6 A, which must be considered when sizing circuit protection. For diagnostics and service, an RS-232 port exchanges data at 115 kBaud over cables up to 15 m.

Signal integrity at the sensor side is maintained by a D-Sub 15-pin connector that sources 11.6 V at up to 500 mA, which is sufficient for typical incremental or SSI transducers without external power supplies. On the network side, the embedded Ethernet transceiver follows the 100 m point-to-point limitation of copper runs and operates on the IEEE 100Base-TX physical layer, so standard Cat-5e cabling is suitable. The internal microcontroller shapes drive-enable pulses as narrow as 60 ms for quick reaction to line-shaft synchronization, while certified Safe Motion functions allow the drive to meet performance level requirements for monitored stop or safely limited speed without extra hardware.
