Product Description:

The CDB01.1C-SE-NNN-NNN-NNN-NNN-NN-S-NN-FW is a modular control unit produced by Bosch Rexroth Indramat for the CDB Control Units series. Installed within IndraDrive servo platforms, the card coordinates motion and I/O for multi-axis machinery by translating fieldbus commands into current, position, and diagnostic tasks. By housing the real-time processing for two drive channels, it serves as a compact controller that links higher-level automation systems to the individual power sections used in industrial automation. Because it is modular, the unit can be fitted into a broader drive assembly without placing separate motion-processing hardware elsewhere in the cabinet.

At the core of the module, the drive processor supervises 2 controlled axes and exchanges deterministic data with the master controller over SERCOS II fiber. Fast torque regulation is achieved through a 125 µs current loop, allowing tight velocity and position correction during dynamic motion. For conventional process variables, the board offers 1 analog input that is sampled and filtered internally, and 2 analog outputs that can drive loads down to 5 kΩ with a granularity of 19.5 mV/inc. These analog channels allow temperature, pressure, or speed references to operate alongside the digital motion profile without requiring additional interface hardware.

Discrete signaling is completed by transistor outputs rated at 500 mA, which is sufficient for contactors or optical indicators. During idle operation, the electronics draw 9 W of base power, which simplifies cabinet thermal calculations and keeps the shared 24 V rail lightly loaded. SERCOS telegrams can be exchanged every 1000 µs, so the platform can synchronize slower peripheral stations while maintaining high-resolution current control. Remaining resources include two probe inputs of type 2 and type 3 for capture tasks, a 6 A inrush limiter that protects the backplane, an I/O supply demand of 1.1 A, a maximum output pulse width of 60 ms, and a relay contact that switches 24 V DC at 1 A. The mix of digital and analog support functions lets the module handle auxiliary signaling and event capture in the same control space.
