Product Description:

The CDB02.1B-ET-EC-EC-PB-S4-S4-NN-NN-AW control unit is produced by Bosch Rexroth Indramat and belongs to the CDB Control Units series. It is intended for multi-axis drive installations where it serves as the primary interface between feedback devices, safety modules, and fieldbus networks. By combining encoder data, internal logic, and external commands, the unit aligns connected servo axes with the motion requirements found in automated assembly, packaging, and machining systems. Its role is to coordinate signal flow between motion hardware and higher-level controls while maintaining stable communication across connected axis channels.

An analog output resolution of 6 mV/incr allows fine reference signals for external amplifiers or sensors. Axis 1 and Axis 2 both use Multi-Encoder interfaces, and each channel supports Safe Motion functions for integrated safety operation. The base electronics draw 23 W during idle operation, while the logic circuits are supplied from a separate DC 24 V source. For real-time communication, the controller provides a Multi-Ethernet port set alongside a dedicated PROFIBUS option that handles cyclic process data. The front-mounted HAP01.1A control panel uses a single-line display for setup and alarm viewing. Relay outputs and digital status lines support external signaling and interlock functions.

Program and data retention are handled through a microSD card slot as well as internal flash areas of 16 MB for code storage and 2 MB for dynamic process variables. A 32 kB retain memory preserves critical flags across power cycles, so essential status data remains available after a restart. The panel relay can switch up to 1000 mA, enabling direct actuation of indicator lamps or interlock coils without extra relays. This arrangement allows the unit to manage two independent axes while keeping memory access, diagnostics, and I/O response within the same control platform.
