Product Description:

The CDB01.1C-S3-NNN-NNN-NNN-MA1-NN-S-NN-FW control card is produced by Bosch Rexroth Indramat within the CDB Control Units series. It functions as the logic layer that slides into Rexroth drive platforms and coordinates motion for multiple axes in automated machinery. By generating setpoints, processing feedback, and passing data to higher-level PLCs, the card links precision servo drives to plant-wide networks and supports deterministic real-time motion control in industrial automation cells.

Internally, the unit supervises 2 motion channels and exchanges command data through SERCOS III, enabling synchronous cycle timing across drives. A base analog output of 5 V at 1 mA is provided for reference generation to external regulators. The MA1 expansion adds two differential analog input channels, and each sample is digitized with 12-bit precision while the converter advances in 5 mV/inc steps, allowing fine scaling of sensor voltages. For position capture, the probe interface delivers timing resolution of 1 µs, while its opto-isolated input accepts 24 V at 3 mA to match standard inductive probes. No integrated safety technology is included, so machine-level safety must be handled by external circuitry.

The output side of the MA1 board supplies two analog channels. Each channel leaves the converter at 12-bit resolution and follows an identical 5 mV step size to preserve linearity when driving valves or torque amplifiers. Discrete control is supported by a relay contact rated at DC 24 V, 1 A, permitting field-wired enable loops without external relays. Local setup is handled through the standard operator panel that mounts on the front edge of the control section. When serial diagnostics are required, the card exposes an RS232 interface whose maximum transfer rate is 115 kBaud, giving sufficient bandwidth for parameter transfers and diagnostic tasks.
