Product Description:

The CSH01.1C-PB-EN1-NNN-NNN-S2-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive modular stack, it supervises position, velocity, and safety functions for servo axes in automated machinery. By combining fieldbus communication, analog processing, and integrated safety logic, the unit coordinates motion commands with feedback devices and higher-level PLCs, allowing precise and protected operation on factory lines.

An analog input resistance of 160 kΩ minimizes loading on upstream sensors, while the analog output steps of 19.5 mV/inc permit fine reference signals to external drives. Internal demand on the cabinet power supply stays low because base consumption is only 7.5 W. During start-up, the controller briefly draws an inrush current of 4 A, so fuses and wiring must accommodate that peak. Eleven onboard digital inputs provide direct connection for limit switches or interlocks, and their count is 11. Four transistor digital outputs return status flags to peripheral devices. A DC 8 V encoder supply powers incremental encoders, and resolver feedback is supported through AC 18.2 Vpp excitation at 4 kHz. The RS-232 port can be cabled up to 15 m without repeaters, allowing flexible local access.

High-speed machine networks connect through PROFIBUS-DP, and the interface sustains a data rate of 12 MBaud for deterministic exchange with the cell controller. The integrated relay channel handles switching tasks up to 24 V / 1 A, letting the section actuate contactors or signal towers. When parameter adjustments are made locally, the serial port transmits diagnostics at a peak of 115 kBaud. All electronics operate from a stabilized bus voltage of DC 24 V, and Safe Motion technology monitors the axis to help prevent hazardous movement during setup or emergency stops.
