Product Description:
The CSH01.1C-NN-EN1-NNN-NNN-L2-S-NN-FW is a control section from Bosch Rexroth Indramat’s CSH Advanced Controllers series. Installed in a compatible IndraDrive power section, it provides the axis processor, analog channels, and communication links that coordinate motion sequences and discrete I/O in automated production cells. These functions allow one module to handle closed-loop control tasks together with local signal exchange inside the drive assembly. Serial diagnostics are available through an RS-232 link that reaches 15 m and supports rates up to 115 kBaud, so local parameter access is possible without a fieldbus master.
The analog front end accepts feedback signals across a bandwidth of 1.4 kHz, which indicates how quickly the controller can respond to changing sensor voltages. A high input impedance of 160 kΩ minimizes loading on source circuits, while the input converter steps voltage changes in 1.23 mV/inc increments for fine resolution. Analog actuators can be connected to loads of 5 kΩ, and each channel can source up to 1 mA for proportional devices. The digital sourcing group has a collective rating of 1000 mA to help protect the printed circuit traces on the board. The probe input captures edge transitions as short as 4 µs, and standard position-latch functions support a configurable maximum pulse duration of 100 ms for time-sensitive event capture.
The D-sub-based EN1 option card adds 6 W to the assembly, while the base electronics draw 7.5 W during steady operation and momentarily pull 4 A when the drive DC link charges. Each analog output steps commands in 19.5 mV/inc increments, which helps external reference signals follow controller data tables with minimal rounding error and smoother proportional updates. The safe torque-off circuit draws only 3 mA, allowing light-gauge wiring in the emergency-stop loop. Total sourcing per discrete channel is limited to 500 mA, so protective components are not overloaded when inductive loads are switched.
