Product Description:

The CSH01.1C-CO-EN2-ENS-MEM-S1-S-NN-FW is a control section from the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. It is installed in IndraDrive power units to execute axis control, fieldbus communication, and encoder evaluation inside automated machinery. Serving as the signal-level brain of the drive, it converts motion commands from the higher-level PLC into precise current and velocity loops for the power stage, making it a central component for coordinated multi-axis automation.

This controller draws 7.5 W from the common 24 VDC supply rail and exchanges cyclic data over the fieldbus pair CANopen / DeviceNet. Its onboard emulator can produce feedback pulses up to 1 MHz so legacy drives that expect incremental signals can still follow the commanded trajectory. The first encoder channel accepts EnDat 2.1, 1 Vpp, or 5 V TTL formats and provides a dedicated output of 350 mA at 5.0 VDC; shielded cabling can be routed as far as 75 m without signal-sense dropout. In addition, the section can present SSI-based absolute or incremental position data to external controllers, allowing mixed feedback topologies within the same machine.

The second encoder port targets IndraDyn, Hiperface, or 1 Vpp sensors and digitizes the analog track with a resolution of 12 Bit. For transducers that need more power, it supplies 500 mA at 11.6 VDC, enabling long-stroke motors to report position without auxiliary supplies. Functional safety wiring is supported through galvanically isolated terminals that accept 24 VDC inputs and can switch dual-channel outputs up to 0.5 A; an internal relay rated for 24 VDC, 1 A allows direct control of contactors or emergency stop chains. These resources complete the feedback, communication, and safety envelope introduced above, allowing the CSH control section to integrate seamlessly into modern drive architectures.
