Product Description:

The CDB01.1C-S3-ENS-ENS-NNN-NNN-NN-S-NN-FW control unit is produced by Bosch Rexroth Indramat within the CDB Control Units series. It serves as a plug-in drive controller section that coordinates motion on multi-axis IndraDrive platforms, delivering command processing, encoder evaluation, and fieldbus exchange for two servo axes in automated machinery. In packaging lines, pick-and-place stations, and conveyor zones, it provides the computational layer between the power section and higher-level PLCs and supervisory networks.

For internal signal conversion, it uses a 12-bit A/D stage and an analog bandwidth of 500 kHz, allowing high-speed capture of feedback signals. Two analog output channels deliver 1 mA at 5 V for reference commands or test points. Motion data are exchanged over SERCOS III through a shielded RJ-45 (8-pin) connector, while a fallback RS-232 port supports service access. Base consumption is limited to 9 W, and the S3 option adds only 1 W. At power-up, the unit can draw 6 A of inrush current, so upstream devices must tolerate that momentary load. Differential encoder inputs present a 120 ohm termination and evaluate HIPERFACE, EnDat 2.1, or 1 Vpp signals through two standard 12 V interfaces. The encoder supply provides 12 V at 500 mA and remains within a 12.3 V ceiling for the two-axis architecture.

The I/O section requires an external 24 V supply. It can furnish up to 0.5 A on the four digital output lines and accepts 1.1 A for combined sensing loads. A TTL capture input operates at frequencies up to 400 kHz, enabling edge-accurate measurement of rapid switch or encoder pulses. The inrush impulse lasts only 60 ms, which helps reduce nuisance tripping in protective breakers. The same 24 V rail also feeds the outputs, which operate at a 24 V logic level and switch inductive loads through integrated clamp circuits.
