Product Description:
The CSH01.1C-NN-EN2-NNN-MA1-S2-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive power stage, it provides axis control, feedback evaluation, and integrated safety functions needed in automated equipment. It converts field-level signals into drive commands so that packaging, printing, and machining systems can maintain repeatable speed and position during continuous operation.
The base analog input resistance is 160 kOhm, which reduces current draw from sensitive transducers. Each channel is resolved in steps of 2 mV/inc, allowing fine adjustment in pressure, force, or tension loops. The MA1 mezzanine includes two differential analog inputs and generates command voltages with a resolution of 12 bit, which suits the dynamic range used by most servo amplifiers. Encoder feedback is accepted in EnDat 2.1, 1 Vss, or TTL formats, and the input is low-pass filtered at 500 kHz to help prevent high-frequency interference from affecting sine or cosine signals. The same interface provides a regulated 5.0 V supply for connected sensors, which allows feedback devices to be powered directly from the control section.
Machine-level discrete signals are handled through four configurable digital lines and 7 dedicated inputs. Along with 2 analog outputs, the board can monitor limits, react to trigger events, and issue reference values from one slot. A form-C relay rated at DC 24 V / 1 A is available for holding-brake release or contactor enable control. Integrated Safe Motion functions, including safe stop and limited speed, reach SIL2 / Cat. 3 PL d when the enable chain is wired to the required category. Operation is performed from the standard control panel, and optional fieldbus modules can be added because built-in communication options are not included.
