Product Description:

Bosch Rexroth Indramat manufactures the CDB01.1C-PB-ENS-EN2-NNN-NNN-NN-S-NN-FW control module as part of the CDB Control Units series. The device is a modular drive controller component that hosts two motion axes and acts as the central processing layer between power sections and higher-level automation equipment. In industrial automation, its purpose is to coordinate servo drives, issue setpoints, and collect feedback so that positioning, velocity, and process variables remain within programmed limits.

The unit supervises 2 synchronized axes and exchanges cyclic setpoint and diagnostic data over PROFIBUS, allowing integration with PLCs that use this fieldbus as a deterministic backbone. Commanded analog values leave the board with a resolution of 19.5 mV/inc, giving fine granularity when the drive must generate precise torque references. Digital inputs register an ON state once the signal reaches 15 V, while each digital output can source up to 500 mA, permitting direct actuation of contactors or signal lamps without external amplifiers. Encoder socket XG31 supports IndraDyn and Hiperface protocols, while socket XG32 accepts EnDat 2.1, 1 Vpp, or 5 V TTL feedback. The En2 port delivers 350 mA so second-channel sensors remain powered during high-speed probing operations.

Overall load on the logic rail may reach 1000 mA, a margin that accounts for the 350 mA drawn by the secondary encoder and any additional I/O loads. That rail is stabilized at 5.0 V, which aligns with the voltage demand of most TTL feedback devices. Two probe inputs accept pulses no shorter than 4 µs, enabling edge capture during fast tool measurement, and each relay contact switches up to 30 V DC at 1 A for auxiliary interlocks. A built-in RS232 port supports local setup, and external safety relays are required because no integrated safety technology is present.
