Product Description:

The CDB01.1C-ET-ENS-ENS-NNN-MA1-S2-S-NN-FW is a modular control unit from Bosch Rexroth Indramat that belongs to the CDB Control Units series. Designed for multi-axis drive applications, the module coordinates motion commands, manages safety signals, and links drives to higher-level automation networks. By combining local analog and digital I/O with fieldbus and Ethernet connectivity, the unit acts as the control layer inside IndraDrive servo systems. This arrangement lets one module supervise axis behavior, exchange status data with connected devices, and keep cabinet layouts compact.

The unit coordinates motion on 2 axes and maintains deterministic response with a base draw of 9 W from the 24 V control supply. Its RJ-45, 8-pin port complies with the 100Base-TX standard, allowing fast data exchange across Ethernet-based automation networks. When the cabinet is first energized, the electronics demand an inrush of 6 A, which helps set protection for the control circuit. The MA1 option adds two inputs and two outputs with 12-bit resolution, and each channel operates across a ±10 V signal range. A dedicated RS-232 serial interface is available for diagnostics and local service access.

The safety block connects through a D-Sub, 9-pin female plug and is integrated directly into the controller. Each safe input operates at 24 VDC, 3 mA, while the solid-state outputs are rated for 24 VDC, 0.5 A to drive contactors or indicator lamps. An auxiliary relay can switch loads up to 24 VDC, 1 A for redundant shutdown chains, and the permissible pulse width on safety signals is limited to 60 ms. The ENS encoder interface draws only 6 W, which helps keep internal heat generation low when feedback modules are installed. Separate safety, encoder, and communication connections help organize wiring in dense drive cabinets.
