Product Description:
The CDB01.1C-S3-EN1-EN1-NNN-NNN-L2-S-NN-FW control unit belongs to the CDB Control Units series manufactured by Bosch Rexroth Indramat. Designed for multi-axis IndraDrive automation, this plug-in board hosts motion and safety logic for a single drive slot, coordinating power stage firing, feedback processing, and fieldbus traffic. Within an installation, it serves as the central command layer, translating network telegrams into precise torque, speed, or position commands that keep servo axes synchronized with PLC sequences in packaging lines, machining centers, and material-handling cells. Its compact card format fits directly into the drive rack and supports a space-efficient control layout.
During idle operation, the unit draws a base power of 9 W, which helps with control-cabinet power sizing and thermal planning. The dedicated encoder slot consumes an additional 6 W when energizing the resolver or high-speed feedback interface supported by this model. The HSF circuit presents an input resistance of 10 kΩ, accepts an 8 V DC sensor supply, and can deliver up to 250 mA to external transducers. When a resolver is connected, the board delivers a carrier frequency of 4 kHz with a differential drive of 18.2 Vpp and a maximum secondary current of 70 mA, helping maintain clean sine-cosine signals for closed-loop commutation.
Fieldbus exchange relies on SERCOS III through an RJ-45, 8-pin port, and it can work with optical media converters when ring redundancy is required. To protect connected machinery, safe torque off inputs require 24 V at 3 mA and return status through a 24 V DC, 1 A feedback contact. Power-up transients are limited by a maximum inrush pulse of 60 ms and a typical inrush current of 6 A, which helps prevent breaker trips during energization. The auxiliary S3 expansion zone draws only 1 W when enabled, so cabinet heat remains low during continuous network communication.
