Product Description:

The CDB01.1C-ET-ENS-ENS-EN2-MEM-S2-S-NN-FW is a modular motion control unit produced by Bosch Rexroth Indramat within the CDB Control Units series. Designed for cabinet-mounted drive systems, the module functions as the central processor that interprets feedback from multiple encoders, exchanges real-time data with higher-level PLCs, and issues velocity and position commands to drive inverters. By integrating standardized Ethernet communication and encoder evaluation hardware in one slot, the device streamlines multi-axis coordination in industrial automation cells such as pick-and-place gantries, packaging machines, and material-handling lines.

The unit supervises two synchronized drive channels, matching its axis count of 2 to medium-sized machinery where coordinated motion is required. Data exchange with field-level networks is handled through the Multi-Ethernet interface, allowing protocol selection without hardware changes. Physical transport follows the 100Base-TX standard, so the wiring can use standard Cat-5e copper at 100 Mbit/s. High-resolution position feedback on the secondary encoder port accepts EnDat 2.1 signals as well as 1 Vpp and 5 V TTL formats, giving flexibility when mixing absolute and incremental transducers. A dedicated memory module clocks internal capture and compare functions up to 1 MHz, ensuring precise time stamping of encoder events. The RS-232 service port transmits at rates up to 115 kBaud for parameter download and diagnostics.

Safe motion monitoring is carried out onboard; the embedded safety layer is certified for Safe Motion, letting the controller cut torque or restrict speed without an external relay module. Safety inputs operate at 24 V / 3 mA, while dedicated transistor outputs switch feedback signals at 24 V / 0.5 A, and an internal relay is rated for 24 VDC / 1 A to interrupt power to contactors. Two ENS interfaces supply 12 V excitation to motor encoders. The auxiliary EN2 connector provides a regulated 5 V feed for secondary sensors. These separate voltage domains support encoder supply and safety signal handling within the control unit.
