Product Description:

The CDB01.1C-PB-NNN-NNN-NNN-MA1-NN-S-NN-FW is a configurable control unit manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Mounted on an IndraDrive power section, it provides real-time signal processing that converts fieldbus commands to internal torque, speed, and position references. Within automated production lines, the board links higher-level PLCs with servo hardware so each axis can execute coordinated motion sequences.

At the system level, the card exchanges cyclic data over PROFIBUS-DP, and its integrated controller sustains a bus speed of 12 MBaud to synchronize multiple drives. The standard I/O block accepts discrete inputs rated at 24 V / 3 mA for sensors and delivers discrete outputs of 24 V / 0.5 A for actuators or status lamps. A base analog channel can source 5 V / 1 mA, providing a reference for external control circuits. This mix of fieldbus communication, digital I/O, and analog signaling supports both centralized control and local machine interlocks. Startup energization draws an inrush of 6 A, and input capture remains reliable for pulse widths up to 60 ms. Relay contacts on the board are rated for DC 24 V at 1 A, providing a direct path for brake or contactor control.

The extension interface adds two differential input channels that present 1000 kΩ of impedance and convert signals with 12 bit resolution. On the output side, two analog output channels drive up to 10 mA into loads as low as 1 kΩ while matching that conversion precision for reference generation. Setup and diagnostics can be handled through the RS232 serial port, allowing parameter access even when the fieldbus is inactive. The same interface supports both differential feedback signals and analog reference values. Steady-state current remains within the nominal operating range during normal logic operation.
