Product Description:

The CSH01.1C-S3-ENS-ENS-NNN-NN-S-NN-FW controller is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It is a single-axis control section intended to manage drive amplifiers and peripheral I/O inside modular automation systems. By combining motion processing, field communication, and local signal conditioning, the unit coordinates servo motors and external sensors within a deterministic network. This arrangement allows the control section to handle axis commands, feedback evaluation, and machine-level signal exchange within the same drive platform.

The control electronics are energized by a regulated input of DC 24 V, which powers internal logic and keeps parameter memory alive during main-power drops. Command and feedback data move over SERCOS III; this real-time protocol passes cyclic setpoints through the RJ-45 interface while maintaining very tight timing. When the application requires standard factory Ethernet access, the integrated PHY supports 100Base-TX for diagnostic traffic up to the stated network length. For analog actuator references, one channel provides a full-scale swing of 5 V. Discrete machine states enter through opto-isolated inputs that recognize 24 V / 3 mA, and status bits exit on sourcing outputs rated at 24 V / 0.5 A, allowing direct actuation of contactors or indicator lamps without auxiliary relays.

Encoder feedback wiring is terminated inside the module against an input impedance of 120 ohms, a value chosen to match twisted-pair line characteristics and minimize signal reflections. The SERCOS trunk can span up to 100 m between nodes, which supports cabinet-to-cabinet layouts without repeaters. Even with all communication ports active, the electronics draw only 7.5 W, reducing thermal load in densely packed drive racks. Additional provisions include an 11.6 V sensor supply at 500 mA, 4 A inrush limitation, 100 ms maximum pulse capture, and relay contacts rated for 1 A at 24 V DC.
