Product Description:

The CSB01.1C-S3-ENS-EN1-NN-S-SS-FW control section is manufactured by Bosch Rexroth Indramat as a member of the CSB Drive Controllers series. Installed inside an IndraDrive power stage, this module supplies motion commands, feedback processing, and diagnostic handling for one connected servo axis. In industrial automation, it serves as the logical core that links fieldbus data to motor control, enabling coordinated speed, torque, and position regulation without a dedicated PLC. It plugs into the power section through a backplane connector, avoiding external control wiring. This arrangement keeps the control electronics close to the power stage and supports compact cabinet layouts.

The board manages a single-axis channel, so every current, velocity, and position loop is devoted to one mechanical load. Real-time traffic toward upper-level devices moves through SERCOS III, delivering synchronized update cycles across multiple drives. A maintenance RS-232 port permits local setup and console commands. Primary feedback enters through a multi-protocol connector that accepts IndraDyn, Hiperface, 1 Vpp, and 5 V TTL encoders, allowing both incremental and absolute sensors. That range lets the control section work with several common motor feedback formats in mixed installations. Discrete machine signals are brought directly to the front edge through inputs and outputs, reducing the need for additional I/O hardware.

For nonvolatile storage, the parameter card slot accommodates a MultiMediaCard, allowing parameter data to remain on removable media. The unit has 1 option slot that can accept plug-in cards, and the base design already provides a relay output suitable for brake or contactor actuation. An auxiliary encoder adapter for MHD and MKD motors can be added when required. The resident operator panel is standard for local adjustments and front-panel status access. Because no integrated safety technology is present, external safety relays must be used.
