Product Description:

The CDB01.1C-SE-EN1-EN1-NNN-NNN-L1-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Installed on an IndraDrive power section, it functions as the command processor that links motion controllers, feedback devices, and safety circuits during machine operation. By combining encoder evaluation, fieldbus exchange, and local I/O handling, the unit directs coordinated drive behavior across connected axes in automated production lines.

The I/O electronics are supplied with DC 24 V, and the board can draw up to 1.1 A from that rail to power sensors, actuators, and internal logic. Motion control capability extends to 2 axes, allowing synchronous positioning or independent regulation per channel. Real-time communication is handled through the Sercos II fiber-optic bus, which transports setpoints, status words, and diagnostic data with low jitter. Each analog monitor channel provides a maximum source current of 1 mA, enabling current-limited feedback to external indicators without overloading the converter stage. Encoder Interface 1 and Encoder Interface 2 both accept HSF or resolver signals so the unit can read absolute rotor angle and speed directly from each motor.

A separate analog path can deliver up to 5 V, and its Type 2 converter steps that range in increments of 19.5 mV/inc for fine voltage tracking by a higher-level PLC. Local access is available through the standard control panel, while parameter downloads or service tasks can be performed via the RS232 port that terminates on a Mini-DIN 8-pin female connector. Functional safety relies on a dedicated D-Sub 9-pin female input; it admits 3 mA per channel and provides the integrated Starting Lockout function that inhibits drive enable until all protective contacts are closed.
