Product Description:

The CDB01.1C-SE-EN1-EN1-NNN-NNN-L2-S-NN-FW is a modular control section produced by Bosch Rexroth Indramat within the CDB Control Units series. Installed on a compatible power section, the board supervises two motion axes, provides analog and digital I/O, and exchanges real-time data with higher-level automation controllers. In drive systems, it executes the command-processing layer, translating network telegrams into current-loop commands and encoder feedback for precise positioning, steady velocity regulation, and integrated safety functions in packaging, printing, and material-handling lines.

The board manages 2 axes and provides 1 analog input for differential ±10 V reference signals, while actuator signals can be sent through 2 analog outputs. Command traffic travels over SERCOS II, and the internal torque loop is refreshed every 125 µs to keep current response and speed correction tightly controlled. A basic consumption of 9 W, an inrush demand of 6 A, and an I/O supply draw of 1.1 A set cabinet power needs. Diagnostic access is available through an RS-232 service port that supports 115 kBaud, and relay logic is provided by a single normally open contact rated for a 60 ms pulse.

Functional risk reduction is delivered by the integrated Safe Torque Off channel, which interrupts gate signals without latency when the designated STO terminals receive only the specified 3 mA monitoring current. Feedback from motors enters through 2 MHD/MKD encoder interfaces, letting the controller synchronize commutation angles for both axes. Deterministic bus performance is maintained because the device supports a 1000 µs minimum SERCOS cycle at a physical layer speed of 16 MBaud. This timing supports fast electronic gearing, phase-synchronous camming, and controlled shutdown sequences without external assist circuitry.
