Product Description:

The CDB01.1 C-PB-NNN-NNN-NNN-NN-S-NN-FW control card is manufactured by Bosch Rexroth Indramat as part of the CDB Control Units series. It is inserted into a compatible drive. There it serves as the local processor that converts fieldbus telegrams into real-time axis commands for machine tools, packaging lines, and material handling cells.

Internally, the board supports 2 axes, each served by high-precision analog channels. Command voltages are accepted through inputs that present 160 kΩ of resistance, minimizing load on upstream signal sources. Each increment on these inputs equals 1.23 mV/inc, allowing fine setpoint resolution during velocity or torque control. When the unit drives external devices, it can source reference voltages into loads down to 5 kΩ, and those outputs step in slices of 19.5 mV/inc. Four combined digital I/O points supplement the analog functions, while two Type-2 probe inputs capture edge-triggered position events for tasks such as registration. The integrated PROFIBUS interface manages deterministic bus cycles, and it connects through a 9-pin female D-Sub connector. For parameter backup or diagnostics, a Mini-DIN eight-pin RS-232 port is available, giving direct access without disturbing the field network.

Electrical overhead is modest. Basic logic draws 9 W, and the dedicated PROFIBUS daughterboard requires 2 W, so cabinet ventilation is rarely an issue. Each digital output can deliver up to 500 mA, and the entire group is limited to 1000 mA, enabling the card to switch solenoids or relays without external amplifiers. During power-up, the supply must tolerate an inrush of 6 A for about 60 ms, after which consumption returns to its steady level. The 9 W base demand, 2 W bus load, and low standby leakage simplify power supply sizing across multi-axis racks.
