Product Description:
The CSB01.1C-S3-ENS-NN-NN-S-NN-FW is a drive controller control section produced by Bosch Rexroth Indramat and supplied within the CSB Drive Controllers series. Installed inside IndraDrive modular systems, this control section governs one servo axis and links motion commands to the associated power module. In factory automation, it coordinates velocity, torque, and position loops so electric motors execute programmed trajectories with consistent precision. This arrangement separates control processing from the power stage, which helps the system adapt to different axis demands without changing the basic control concept.
This control section is built for single-channel motion control. Its 1-axis capability pairs one motor with dedicated processor resources, reducing cross-talk in multi-station machines. Real-time communication with upper-level PLCs travels over the SERCOS III fieldbus, allowing deterministic cycle times. For position feedback, the board accepts 1 Vpp and 5 V TTL encoder signals, so both sine-cosine and digital encoders can be connected without external converters. Service laptops or HMI touch panels connect through the RS232 serial interface, which supports parameter upload and diagnostics. Operational parameters are stored through a MultiMediaCard slot, which keeps application data on removable media for straightforward service access.
Local signal exchange with sensors and interlocks is handled by the integrated digital I/O, removing the need for auxiliary terminal blocks. Final stage enable or fault status can be routed to external contactors via the integrated relay output, which switches independently of the drive's low-level logic. If additional process variables are needed, the control section accepts an encoder, analog I/O, and emulation expansion for broader machine interfacing. Motor position data is processed directly from IndraDyn and Hiperface feedback, allowing the controller to close high-resolution loops without additional transducers. This combination supports accurate synchronization with machine sensors, actuators, and external control devices during continuous operation.
