Product Description:

The CDB01.1C-ET-EN2-EN2-EN2-EN2-L2-S-NN-FW is a compact motion-control unit produced by Bosch Rexroth Indramat within the CDB Control Units series. It acts as the command layer for a dual-axis IndraDrive inverter, converting fieldbus traffic and local I/O signals into deterministic drive commands for packaging, material-handling, and assembly machinery. By integrating signal conditioning, safety, and communication resources on one plug-in board, it reduces panel wiring and simplifies system integration in compact multi-axis drive cabinets.

Two differential analog channels accept feedback or reference voltages over a ±10 V window, and their high 160 kΩ input impedance minimizes loading on external sensors and potentiometers. Discrete control follows PLC logic levels, with digital inputs interpreted at 24 V / 3 mA, while actuators can be driven from the onboard outputs that switch 24 V / 0.5 A. An internal bus delivers up to 1.1 A to the I/O section so peripheral devices can share the drive power supply. Position feedback arrives through four EnDat 2.1, 1 Vpp, or 5 V TTL encoder interfaces. Real-time command traffic moves over the Multi-Ethernet port, so EtherNet/IP, PROFINET, or EtherCAT controllers can address the axes without separate option modules.

Each control board governs 2 axes, and the integrated Safe Torque Off function disables motor power without removing mains, providing category 0 stop capability through wiring only. High-speed probing is supported through two Type 2 inputs that latch position within 1 µs, while two analog outputs supply 5 V references at 1 mA for external meters. A removable MultiMediaCard stores parameters for the control unit, while day-to-day access is handled from the standard operator panel for routine setup and diagnostics. Additional diagnostics can be streamed over the RS232 service port, and field devices such as brakes or contactors may be wired to the relay rated at DC 24 V and 1 A.
