Product Description:
The CDB02.1B-ET-EC-EC-EM-S5-S5-NN-NN-FW belongs to the CDB Control Units series produced by Bosch Rexroth Indramat. This modular control card is installed in a drive cabinet and partners with HMD power modules to coordinate torque, speed, and position loops for electric servo axes in automated machinery. By hosting field-level inputs, feedback ports, and network interfaces on a single card, it acts as the central command element that links motion hardware to higher-level PLC programs.
The card supports 2 motion axes and offers symmetrical signal conditioning through two analog inputs and two analog outputs for process variables such as torque bias or following error. Four probe inputs allow latch-type position captures, while 14 digital inputs handle limit switches, homing sensors, or drive enables in multi-sensor stations. Encoder feedback is handled through 2 x Multi-Encoder interfaces that arrive on dual D-Sub 15-pin female connectors, and an additional D-Sub 15-pin male socket provides an encoder emulation path for downstream devices. Command traffic reaches the unit through the Multi-Ethernet platform, so protocols like EtherNet/IP, PROFINET, or SERCOS III can be selected in software. Physical layer compliance is specified at 100Base-TX, giving deterministic 100 Mbit/s links for real-time drive coordination.
Machine safety is embedded through 2 x Safe Motion S5 channels that supervise STO, SS1, and SOS functions independently for each axis. Four configurable digital I/O terminals and a 4-slot option bay allow additional trigger relays, fieldbus gateways, or battery modules as needed. Network cabling terminates on a shielded RJ-45 8-pin connector mounted at the card’s front edge, while power stage interconnection is standardized for the HMD01 inverter section so cabinet design remains consistent across drive sizes. Two analog outputs mirror target position or velocity, and the encoder emulation connector reproduces quadrature or SSI streams for auxiliary displays without loading the primary feedback loop.
