Product Description:
The CDB01.1C-PB-EN2-EN2-EN1-EN1-S2-S-NN-FW belongs to the CDB Control Units series from Bosch Rexroth Indramat. It is a configurable control section that plugs into the modular drive system and coordinates motion axes, diagnostic feedback, and integrated safety functions. By combining sensor interfaces, fieldbus communication, and logic resources, the unit acts as the central intelligence for servo inverter power sections used in automated assembly lines, packaging equipment, and material-handling stations.
At the power input, the board operates from a base supply of DC 24 V, a low-voltage level that simplifies cabinet wiring and allows the device to remain active during mains dropouts. Under idle conditions, the logic electronics draw only 9 W, reducing heat dissipation and conserving auxiliary power in multi-axis installations. Command data exchange with higher-level PLCs takes place through PROFIBUS, so deterministic cyclic telegrams can reach every drive without additional gateways. The first encoder channel supplies high-speed feedback devices with 250 mA at 8 V, and it excites the resolver winding at 4 kHz. These values provide sufficient signal amplitude and bandwidth for precise position capture even at elevated motor speeds.
The second feedback input supports encoders that require 5.0 V reference voltage, and it can deliver up to 350 mA for devices such as EnDat 2.1 or 5 V TTL sensors. Internal interrupt timing is tuned to a maximum pulse width of 60 ms, allowing Safe Motion to detect standstill or overspeed within one controller cycle. When a hazard is detected, the dedicated safety output provides 24 V / 0.5 A to drive contactors or external brakes through the 9-pin female D-Sub safety connector. Additional protective measures include a 6 A inrush limiter that prevents supply dips on startup and dual-resolver support on slots three and four, allowing reliable multi-turn position feedback without external splitters.
