Product Description:
The CSH01.1C-NN-ENS-EN2-NNN-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Mounted in an IndraDrive stack, the board manages servo feedback, analog conditioning, and digital I/O so that higher-level PLCs receive deterministic motion data. Its task in industrial automation is to translate machine-level signals into processed commands that keep axes synchronized during positioning, packaging, or general material-handling cycles. This arrangement lets the control section handle feedback processing and signal conversion within the drive assembly instead of requiring separate interface hardware.
A DC 24 V supply feeds the logic, and the electronics dissipate only 7.5 W, limiting heat generation inside the cabinet. The single-ended analog inputs exhibit 160 kΩ resistance, reducing loading on delicate transducers, while command voltages leave the board in steps of 19.5 mV/inc for fine control of motor speed or pressure loops. The board has 11 opto-isolated digital inputs that accept field signals through spring terminals. Encoder port EN2 carries 120 Ω termination and is specified for square-wave counts up to 1 MHz, and its 350 mA rail is supplied by a 6 W local regulator. The ENS interface offers its own 11.6 V, 500 mA feed, and its internal electronics dissipate 6 W. This allows the module to process encoder signals and local machine I/O on the same control section.
Each sourcing channel can deliver up to 500 mA, allowing direct actuation of contactors or indicator lamps without external relays. Cabinet fuses must accommodate an inrush current of 4 A that appears when the supply is first applied. For pulse-based control tasks, the unit accepts widths as long as 100 ms, enabling low-frequency reference trains alongside encoder processing. Service laptops connect through the diagnostic RS-232 interface, and cable runs may extend to 15 m so a computer can remain outside the cabinet. The output behavior suits compact panels where the control section must switch small loads and still support local diagnostics.
