Product Description:

The CDB01.1C-PB-EN2-EN2-NNN-NNN-L2-S-NN-FW is a modular control unit produced by Bosch Rexroth Indramat for the CDB Control Units series. It slots into an IndraDrive power section to govern motion and I/O in compact multi-axis machinery. By supervising command processing, feedback evaluation, and fieldbus exchange, the board delivers deterministic setpoints to drives that move packaging axes, handling robots, or machining tables while occupying minimal cabinet depth. It acts as the central processor inside the drive stack rather than as a power-switching stage.

At its analog front end, the controller presents an input resistance of 160 kΩ, allowing voltage followers or sensor cards to couple without loading their sources. An isolated analog output is rated at 5 V / 1 mA for speed or torque references to legacy drives. Base electronics consume only 9 W, so thermal rise inside the enclosure remains low. Network communication is handled over PROFIBUS, while a standard control panel offers local parameter access. Eight digital inputs accept a nominal 24 V / 3 mA signal. The unit supervises two axes, and each channel supports 1 µs probe accuracy with a 60 ms maximum latch pulse width for precise position capture. An RS-232 serial port remains available for service tasks and local communication.

The output side provides a sourcing capacity of 24 V / 0.5 A per channel for contactors, solenoid valves, or status lamps, and an internal relay path is rated at DC 24 V / 1 A for floating feedback to higher-level controllers. Both encoder sockets accept the mixed-signal format of EnDat 2.1 with 1 Vpp or 5 V TTL tracks, giving identical feedback handling on each axis. For safety-related stops, the board integrates the certified Safe Torque Off function that cuts drive enable lines without requiring full power removal. Power-up stress on the DC supply peaks at a typical 6 A inrush before settling into normal operation.
