Product Description:
The CDB02.1B-ET-EC-EC-NN-NN-NN-DA-NN-FW control unit is produced by Bosch Rexroth Indramat and belongs to the CDB Control Units series. It serves as the central processing module inside a dual-axis drive package, coordinating analog, digital, and probe signals so connected servo amplifiers receive precise command data. Within an automation cell, the device translates higher-level PLC instructions into motion sequences, position feedback handling, and status information for supervisory software.
An analog input resolution of 14 bit allows the controller to register fine voltage changes from external sensors and reference sources. The analog output conversion time of 250 µs helps command updates remain responsive, and the outputs operate across a ±10 V range commonly used by servo interfaces. The unit manages 2 axes, with two DA analog inputs and two DA analog outputs available for current or velocity references on each axis. Six DA digital inputs and six DA digital outputs add machine interlocking and status exchange, while eight configurable on-board I/O points can be assigned to supporting functions. The board also includes 14 on-board digital inputs that switch high at 15 V, and four probe inputs are reserved for time-stamped position capture.
Installation space is limited to a depth of 103 mm, a height of 322.6 mm, and a width of 49.5 mm, which helps when several drive sections are mounted in the same cabinet column. The slim housing leaves room for wiring paths and adjacent modules without forcing large gaps between assemblies. Each digital output can source up to 500 mA, which allows direct operation of compatible contactors, relays, or indicator lamps. This output capacity is useful when the control unit must exchange field signals without a separate interface board.
