Product Description:

The CDB01.1C-PB-ENS-ENS-NNN-S2-S-NN-FW control card is manufactured by Bosch Rexroth Indramat as a member of the CDB Control Units series. It plugs into IndraDrive power sections and provides the logic, fieldbus, and safety layers needed to run servo axes in industrial automation. By managing encoder signals and exchanging process data with higher-level controllers, the unit lets packaging machines, assembly stations, and material-handling lines synchronize multiple drives from a compact slot inside the cabinet.

This model is energized by a logic supply of 24 V DC and supports coordinated motion for 2 axes. The electronic core draws a base power of 9 W, so heat generation inside the cabinet remains minimal. Drive parameters and commands move across the PROFIBUS interface, reducing wiring while maintaining deterministic cycle times. At startup, the module withstands an inrush current of 6 A for no longer than 60 ms, a profile that helps with fuse sizing and power bus design. A 15-pin D-Sub socket routes encoder feedback, and 12 V sensor power is available for typical SinCos transducers. Safe Motion circuitry delivers a 0.5 A switchable output that can disable torque paths when an emergency guard is opened.

The analog section supplies reference signals to external regulators at up to 1 mA or 5 V. The probe input timestamps position events with an accuracy of 1 µs, aided by an internal comparator that accepts pulses as short as 4 µs. Hardwired safety loops may be routed through the dual-channel relay rated at 24 V DC / 1 A, letting the card interrupt downstream contactors without additional hardware. Diagnostic data can reach a service computer through the RS-232 port, allowing direct access without relying on the primary network connection. Safe Motion technology supervises encoder consistency and speed limits independently of the fieldbus, helping the card respond to unsafe operating conditions even if normal communication is interrupted.
