Product Description:
The CSB01.1 C-SE-EN2-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. This module plugs into a matching power section to form a complete drive controller for servo axes in automated machinery. It processes motion commands in real time, manages motor feedback, and exchanges operating data with higher-level PLCs so position and speed loops remain coordinated during machine operation. Because the control electronics are separated from the power stage, the platform can be paired with compatible drive sections used for different axis requirements.
Data traffic between this control section and other modules is carried over a Fiber Optic backplane that supports high-speed transmission with strong noise immunity. Network synchronization is handled through SERCOS II, allowing deterministic control cycles across multiple drives. The integrated encoder interface supports IndraDyn resolver feedback, Hiperface sinusoidal encoders, and incremental signals in 1 Vpp and 5 V TTL formats. This broad feedback support lets the control section work with several motor and encoder combinations without separate interface converters. The digital signal block includes integrated digital I/O, which reduces the need for separate terminals when only a limited number of field points are required.
User interaction takes place through a standard operator panel, and a front slot accepts a MultiMediaCard for parameter storage and data transfer. A laptop can connect through RS232 to access diagnostics if the fiber network is unavailable. Option bays add encoder, analog I/O, and encoder emulation functions, while an auxiliary interface supports EnDat 2.1 for absolute feedback connections. The control section does not include integrated safety functions, so emergency stop and safe torque off functions must be provided by external devices.
