Product Description:

The CSH01.1C-PB-EN2-ENS-NNN-S1-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive power unit, it supplies axis-specific processing, signal conversion, and coordination functions that keep servo drives synchronized with plant-level sequencing. Its role in industrial automation is to translate motion commands into precise electrical instructions while exchanging process data with higher-level PLCs through the integrated PROFIBUS interface and dedicated safety I/O channels.

The housing measures 49.5 mm wide, 241 mm high, and 103 mm deep, so it occupies only one slot in a multi-axis rack. Control electronics draw 7.5 W from the 24 V base supply, and power-up is limited by an inrush of 4 A. The analog reference port accepts a differential signal of ±10 V, which is useful for velocity or torque setpoints, while feedback or diagnostic values can be retransmitted through a 5 V, 1 mA analog output. Field communication is handled by PROFIBUS-DP; the bus enters through a D-Sub 9 female connector that sits beside a matching D-Sub for the safety channel. Internal pulse generation has a maximum width of 100 ms, allowing the controller to support wide trigger sequences.

Encoder wiring is supported on two option channels. The first provides EnDat 2.1, 1 Vpp, or 5 V TTL formats and is powered from a dedicated 5.0 VDC, 350 mA rail, while the second handles IndraDyn or HIPERFACE signals with its own 11.6 VDC, 500 mA supply. Safe shutdown or standstill monitoring is executed through the integrated Safety Technology I/O, which shares the same D-Sub hardware used for control-reliable inputs and outputs. This arrangement supports fast motion loops, analog interfacing, and certified safety functions in a compact drive-mounted controller.
