Product Description:

The CSB01.1C-C0-ENS-NNN-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat for use in the CSB Drive Controllers series. Mounted on a matching power module, it provides the processing layer that handles encoder signals, manages fieldbus communication, and issues drive-enable commands. In automated machining centers, packaging lines, and gantry systems, the board converts high-level motion instructions into precisely timed reference values for the power stage so closed-loop speed and torque regulation can be maintained at each servo axis. This arrangement lets the power stage focus on current delivery while the control section manages timing and feedback evaluation for coordinated motion.

The unit draws logic power from a dedicated 24 VDC rail, and the electronics dissipate only 8 W during steady operation. Startup demand is higher, with a surge of 4.5 A that can last up to 110 ms, so the supply must tolerate brief inrush current. All fieldbus wiring terminates at an X60 spring terminal with five contacts, and the communication interface supports CANopen as well as DeviceNet. Feedback ports accept 1 Vpp or 5 V TTL encoder formats, allowing the same control section to work with sin-cos or incremental measuring systems without external adapters. Because communication handling and encoder evaluation are combined on one module, cabinet wiring stays compact and signal routing remains straightforward.

On the network side, the board can participate in topologies with up to 127 CANopen stations or 64 DeviceNet stations, allowing multiple drives to be distributed across one machine. The module is rated for a maximum of 20 plug-in actions before connector wear becomes critical, so repeated removal should be limited during service. Encoder excitation is supplied by a regulated 12 V output rated at 500 mA, which helps maintain stable sensor power across long cable runs. The available node count and dedicated encoder supply support use in multi-axis equipment where communication stability and consistent feedback signals are both important.
