Product Description:

The CDB01.1C-ENS-ENS-NNN-MA1-NN-S-NN-FW is a dual-axis control section developed by Bosch Rexroth Indramat for the CDB Control Units series. Installed on a compatible power section, it forms the supervisory layer that executes drive commands, conditions analog references, and manages encoder feedback for synchronized machine axes in packaging lines, material handling frames, and general automated equipment. The board also has expansion slots so safety and interface modules can be added without enlarging the drive cabinet. This layout supports compact drive assemblies where control, feedback handling, and optional add-on functions must remain in one housing.

With an architecture that supports 2 independent axes, the unit’s base electronics draw only 9 W from the shared backplane, while the logic is energized by a control bus at DC 24 V. During initial power-up, the capacitors charge with an inrush current of 6 A, which is useful when selecting upstream protection and control power capacity. The integrated MA1 mezzanine provides two differential analog inputs and two analog outputs, each spanning ±10 V, and conversion accuracy is maintained by a 12-bit converter. The analog path accepts or generates full-scale values with a maximum pulse width of 60 ms, allowing the controller to handle slow-changing process signals without clipping. This arrangement supports stable signal exchange between field devices and the attached power section.

Feedback connections are routed through a 15-pin D-Sub female connector that carries position data while supplying the encoder with 12 V excitation. Supervisory commands, parameter data, and diagnostics travel over the integrated RS-232 link, which can transmit at rates up to 115 kbaud. Two safety slots accept optional functional-safety cards, so shutdown channels can be added without external relays and without reallocating the existing I/O budget. This helps the control unit accommodate added safety functions while keeping the main wiring structure unchanged.
