Internal Product Review
The CDB01.1C-SE-EN1-EN1-EN2-EN2-NN-S-NN-FW is a Bosch Rexroth Indramat CDB control unit with Sercos II communication and 9 W base power consumption. EN1 feedback handling is especially well executed, combining 8 V HSF supply voltage with 18.2 Vpp resolver supply voltage for stable signal support. Fast electrical response with 6 A inrush current over a 60 ms pulse gives the control unit a polished, application-ready profile.

Product Description:
Bosch Rexroth Indramat builds the CDB01.1C-SE-EN1-EN1-EN2-EN2-NN-S-NN-FW as a modular control section within the CDB Control Units series. The module plugs into IndraDrive power stages and provides the logic, feedback processing, and fieldbus interface that coordinate servo axes in industrial automation. It converts command data from higher-level controllers into drive-ready signals while also sending status information back to the control system, so it functions as the central motion interface for packaging lines, material-handling stations, and general machinery.
The unit’s electronics draw a base load of 9 W, a low figure that helps keep cabinet thermal rise minimal. All real-time communication with the drive system is handled through the SERCOS II optical ring, ensuring deterministic cycle timing. Command switches and sensors can be wired to the digital inputs, which accept a nominal 24 V / 3 mA signal level. For analog reference tasks, the first output operates at 5 V / 1 mA, and each increment is resolved at 19.5 mV/inc, enabling fine velocity or torque trimming. A relay on the front panel can switch DC loads up to 24 V at 1 A for drive enable or brake release logic. Feedback supplies include 8 V at 250 mA for Hall-sensor heads, a 4 kHz resolver excitation with 18.2 Vpp amplitude, and an auxiliary 5 V sense rail to the EN2 encoder.
During power-up, the control board withstands an inrush of 6 A that lasts no longer than 60 ms, helping prevent nuisance fuse trips when multiple axes energize together. The EN2 encoder rail can source 350 mA, and its regulated 5.0 V keeps digital encoders within tolerance. Fiber-optic plugs lock down with a tightening value of 0.6 Nm, which helps maintain link integrity against vibration. A probe input captures position-latch events with 1 µs accuracy, supporting synchronized print-mark or registration moves in high-speed machinery.
