Product Description:

The CSH01.1C-PB-ENS-EN2-EN2-S1-S-NN-FW control section is manufactured by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed in IndraDrive modular drives, this component executes axis regulation, fieldbus exchange, and safety monitoring, forming the link between motion commands from the PLC and the power electronics that drive servo motors in automated machinery. It also processes feedback and local I/O signals so the drive can respond to changing machine conditions in real time.

The controller’s analog inputs present an impedance of 160 kΩ, permitting precise voltage measurement without burdening signal sources. Each analog output can source up to 5 V / 1 mA, providing reference values to external converters. At power-up, the base section draws 4 A, and this inrush condition is limited to a maximum pulse duration of 100 ms to protect upstream supplies. Nominal consumption is 7.5 W, so cabinet airflow demands remain modest. For deterministic bus traffic, the unit integrates a PROFIBUS-DP master/slave interface. Twelve digital inputs accept 24 V / 3 mA transitions, enabling connection of proximity switches and limit sensors without extra buffering. Shielded differential converters inside the section raise noise immunity for low-level command paths, and a hardware watchdog supervises every I/O transaction to maintain deterministic update cycles during fast traverse moves.

Command outputs include eight sourcing channels that switch loads up to 24 V / 0.5 A, making them suitable for contactor coils or indicator lamps. The dual EN2 encoder ports supply 5.0 V at 350 mA with a minimum load resistance of 35 Ω and support feedback formats of EnDat 2.1, 1 Vpp, or 5 V TTL. Serial diagnostics are available through an RS-232 port that accepts cables up to 15 m and reaches 115 kBaud. A D-Sub 9 female connector is installed at the S1 service socket, while Safety Technology I/O channels allow wiring of emergency-stop circuits to meet category requirements.
