Product Description:
The CDB01.1C-PB-ENS-ENS-EN2-EN2-L2-S-NN-FW control card is supplied by Bosch Rexroth Indramat as part of the CDB Control Units series. It plugs into a Rexroth drive controller and provides signal conditioning, encoder supply, and Profibus communication for multi-axis systems. Within an automated production line, the card forms the interface that translates fieldbus commands into precise drive pulses, supervises feedback from connected motors, and supports coordinated motion between axes and higher-level PLCs. This arrangement allows command, status, and feedback data to pass through one control stage instead of separate interface modules.
Internally, the unit can coordinate 2 axes, a feature that lets a single controller handle both sides of a gantry or a master-follower pair. Two analog outputs are present, and each is designed to drive a load of 5 kΩ, so external process variables such as torque limits can be set with consistent voltage accuracy. Base power consumption is only 9 W, which helps reduce cabinet heat buildup during continuous operation. The digital inputs recognize an ON state once the signal reaches 15 V, simplifying wiring with typical sensor blocks. For higher-level networking, the integrated Profibus DP port supports data rates up to 12 MBaud, allowing rapid parameter updates and diagnostic exchange without cycle-time penalties. A single normally open relay contact is included for status signaling, and the transistor digital outputs can source 500 mA per channel for interlock solenoids.
During power-up, the supply can draw an inrush of 6 A for 60 ms, a profile that guides fuse and supply sizing. The secondary encoder interface labeled EN2 supports cable runs up to 75 m when sense lines are used; its driver can provide 350 mA at 5 V and maintains signal integrity across a termination of 35 Ω. The primary ENS interface delivers 500 mA at a regulated 11.6 V and passes differential signals with a cutoff frequency of 500 kHz, helping preserve clean feedback from high-resolution encoders during fast motion. These encoder connections allow the control card to manage position feedback while maintaining stable communication with the connected drive system.
