Product Description:

The CDB01.1C-SE-EN1-EN1-EN2-NNN-S1-S-NN-FW control unit is produced by Bosch Rexroth Indramat within the CDB Control Units series. It functions as the command section in modular drive controllers, managing motion sequences, feedback handling, and integrated safety logic for industrial machinery. By hosting multiple communication and encoder channels in a compact card format, the unit simplifies cabinet layouts and provides deterministic coordination between servo drives, feedback devices, and higher-level automation systems. This arrangement supports synchronized multi-axis motion where command timing and signal handling must remain predictable.

Internally, the module draws 9 W of basic power, enough to service the motion electronics for 2 axes. Command data reaches the drive through a SERCOS II fiber-optic ring, and the interface can negotiate rates up to 16 MBaud for cyclic setpoint exchange. An analog output channel provides a reference level of 5 V for external actuators. Each programmable digital output can source up to 500 mA, while the combined load for a group is limited to 1000 mA to protect board traces. Position feedback is accepted through resolver or HSF connections on encoder channels 1 and 2, and a third port supports EnDat 2.1, 1 Vpp, or 5 V TTL transducers. Dedicated sensor lines supply 8 V on EN1 and 5 V on EN2, allowing the card to work with both resolver-based motors and digital encoder systems.

At power-up, the controller presents an inrush demand of 6 A that lasts about 60 ms before the supply stabilizes. The integrated RS-232 interface supports diagnostic connections with cable lengths up to 15 m and data rates up to 115 kBaud. This serial link provides local access to parameters and status data without requiring the real-time fiber-optic channel. Safety Technology I/O is present, allowing direct wiring of emergency stops and light curtains without external safety relays.
