Product Description:
The CDB02.1B-ET-EC-EC-EM-NN-NN-NN-NN-AW is a drive control unit manufactured by Bosch Rexroth Indramat within the CDB Control Units series. Installed next to power inverters in an IndraDrive system, it executes position, velocity, and diagnostic tasks for servo machinery used in automated production. The module links higher-level PLC instructions with the power stage, receives encoder data, manages local I/O, and forwards fieldbus traffic, giving the system an integrated command layer that reduces wiring complexity in multi-axis cabinets.
This version supports 2 axes, allowing synchronized positioning and interpolation inside one housing. All logic is fed from a DC 24 V auxiliary line, and the controller’s base demand is only 23 W, so several units can share a small power supply. Signal conditioning starts with 2 analog inputs that accept ±10 V process values, mirrored by two analog outputs for reference generation. These channels support reference commands, process monitoring, and signal scaling, so low-level analog values can be handled directly at the control unit. A block of 14 digital inputs records limit switches, probe triggers, or safety contacts. Two multi-encoder interfaces read absolute or incremental feedback, and four user-selectable option slots accept communication, safety, or technology cards for application-specific expansion.
For fieldbus tasks, the controller integrates Multi-Ethernet hardware rated at 100Base-TX speed. Wiring is completed through an RJ-45, 8-pin port on the front panel, allowing direct connection to existing industrial switches. Feedback simulation during setup is handled by a D-Sub 15-pin male socket that routes incremental RS422, SSI, or single-ended signals to the drive. The on-board ADC offers 13-bit voltage resolution, capturing sensor changes with fine granularity. A detachable HAP01.1A control panel can be connected for local operation and status access.
