Product Description:

The CDB01.1C-ET-ENS-ENS-NNN-MEM-L2-S-NN-FW is a compact control unit from Bosch Rexroth Indramat that belongs to the CDB Control Units series. Within an IndraDrive cabinet it supervises motion axes, processes field-level signals, and exchanges data with higher-level PLCs through its integrated Multi-Ethernet interface. By coordinating drive parameters and enabling the Safety Torque Off function, the product helps machine builders implement deterministic control and fail-safe shutdowns in industrial automation cells.

This controller accepts 22 digital inputs for limit switches, sensors, and user commands, while 2 analog outputs supply reference values to external actuators or meters. Position feedback is handled through 2 × ENS axis encoder interfaces that support EnDat 2.2 devices without extra option cards. Internal consumption stays at 9 W during runtime, yet cabinet design must tolerate the startup surge because the unit draws up to 6 A of inrush current from the 24 V DC supply. A Multi-Ethernet transceiver negotiates PROFINET, EtherNet/IP, and EtherCAT protocols on the same hardware, so the drive stack can be integrated into mixed-vendor networks without rewiring.

For drive outputs, it supplies up to 500 mA to solenoids and status LEDs, and its emulation channel can stream encoder replacement pulses at 1 MHz for legacy drives that still require incremental or SSI feedback. The encoder terminals deliver 11.6 V through a D-Sub 15 female connector, matching typical absolute encoders. Network wiring is completed on an RJ-45 jack that supports 100Base-TX transfer rates to maintain deterministic cycle times. A maximum pulse width of 60 ms is accepted on fast inputs, allowing capture of brief cam signals, and Safe Torque Off is certified to remove drive power without external contactors.
