Product Description:

The CSB01.1N-PB-ENS-NNN-L2-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed on a matching power module, it completes a servo drive that issues torque and speed commands to a motor and processes encoder feedback in real time. In industrial automation, this board serves as the axis interface, transferring motion tasks from the PLC to the drive electronics while supervising communication, feedback evaluation, and safety functions on one compact card.

The control section is configured for a single-axis drive, so it handles one set of command values, feedback signals, and diagnostics. Fieldbus communication takes place over PROFIBUS, enabling cyclic exchange of position, velocity, and status words with higher-level controllers. Machine-level states can be wired directly because digital inputs and outputs are included, and these points can trigger homing, overtravel, or fault routines without external I/O cards. Precise position acquisition is possible through the sinusoidal encoder channel that accepts 1 Vpp signals, and the board also recognizes IndraDyn and Hiperface formats, so a wide range of Bosch Rexroth and third-party motors can be connected.

Daily operation is supported by the standard operator panel, which provides an LCD and membrane keys for parameter entry when a PC is not available. Status information can be routed to external control circuitry through a dedicated relay output that switches line-level loads such as contactors or signal towers. Integrated functional safety is delivered by the Safe Torque Off circuit, which disables the power stage and prevents unintended motion without adding relays in the motor line. For diagnostics, the board includes an RS-232 serial interface, allowing a direct link to simple terminal or service software.
