Product Description:
The CDB01.1C-SE-ENS-EN2-NNN-EN2-NN-S-NN-FW is a modular control unit delivered by Bosch Rexroth Indramat within the CDB Control Units series. As a plug-in controller card, it is fitted into the manufacturer’s drive system racks to coordinate servo axes and auxiliary components in automated machinery. Its purpose is to translate fieldbus commands into precise drive tasks, manage feedback from multiple encoder formats, and provide analog or digital signals necessary for closed-loop motion control.
During operation, the unit draws a base power of 9 W, so cabinet thermal planning can be kept minimal. At startup, it tolerates an inrush of 6 A, a figure that helps with circuit-breaker sizing. All real-time control telegrams travel over a fiber-optic link that supports the deterministic bandwidth required by SERCOS II. For setup or diagnostic scripting, a dedicated RS-232 port remains available. Two analog monitoring points exist. Output OA1 can source 1 mA or establish a 5 V reference, allowing drive variables to be displayed on external meters. Encoder Interface 1 accepts IndraDyn, HIPERFACE, or 1 Vpp signals, whereas Interfaces 2 and 4 each accommodate EnDat 2.1, 1 Vpp, or 5 V TTL feedback. The card limits each command strobe to a maximum pulse width of 60 ms, preventing unintended retriggering within a single control cycle.
Separate supply rails support secondary electronics. The EN2 logic is fed with 5.0 V and may deliver up to 350 mA to external encoders, while the ENS rail offers 11.6 V with a ceiling of 500 mA for sensors that require higher excitation. These stabilized lines simplify cable layouts by eliminating discrete power supplies near the motor. Safety technology is not integrated, so external safety relays are required if the application calls for them. The card’s fiber backbone coexists with its serial and analog channels without crosstalk, ensuring deterministic timing across multiple axes.
