Product Description:

The CSH01.1C-ET-EN1-EN2-NNN-L2-S-NN-FW is an advanced controller section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. As a control module, it plugs into IndraDrive power sections and coordinates servo axes, I/O, and safety interlocks across machine networks. Its role in industrial automation is to interpret fieldbus commands and generate time-critical drive instructions, allowing synchronized motion and reliable torque cutoff in assembly lines, packaging equipment, and material-handling cells.

Communication is handled by a Multi-Ethernet interface that automatically switches among EtherNet/IP, PROFINET, or SERCOS over standard wiring. The physical link uses an eight-pin RJ-45 socket on the 100Base-TX layer, so cabling lengths and shielding follow standard Fast Ethernet rules. The controller consumes only 7.5 W during normal operation, easing thermal design inside compact electrical panels. For safety, the module implements Safe Torque Off; when the STO inputs are deactivated, motor energy is blocked without auxiliary relays. An RS-232 service port reaches 115 kBaud for service access, while the resolver/HSF channel maintains a 100 kHz bandwidth. Square-wave inputs capture encoder pulses, and the maximum command pulse width is limited to 100 ms to prevent latch overrun.

Separate regulator rails provide 8 VDC for resolver and HSF encoders and 5.0 VDC for EnDat 2.1, 1 Vpp, or 5 V TTL transducers, allowing mixed feedback types on the two encoder sockets without external adapters. At power-up, the card exhibits an inrush of 4 A, so drive system fuses and soft-start elements must tolerate that brief surge. During high-speed capture, the square-wave input runs reliably up to 1000 kHz, supporting linear scales or spindle sensors with fine pitch. The safety control signal is 24 VDC / 3 mA and can be wired directly to standard safety PLC outputs. These electrical limits affect wiring, power budgeting, and fault response in multi-axis machines.
