Product Description:

The CSH01.1C-ET-EN1-EN2-NNN-NN-S-NN-FW controller is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It is a plug-in control section for IndraDrive power units that supervises axis positioning, encoder evaluation, and real-time network traffic inside automated machinery. It processes command data and feedback signals so the connected power stage can respond quickly during coordinated motion. Because it plugs directly into the drive platform, it combines control, feedback handling, and communication in one section rather than requiring separate external interface modules.

The analog front end presents an input impedance of 160 kΩ, so external signal sources are not excessively loaded. Position or process signals are digitized at a granularity of 1.23 mV/inc, while the analog output channel steps in increments of 19.5 mV/inc for drive-level reference generation. Cabinet planning is aided by a depth of 103 mm, a height of 241 mm, and a width of 49.5 mm. This outline lets the control section occupy a single slot beside the power stage without obstructing airflow, and it also helps preserve clearance for neighboring modules and cable routing. The serial interface uses RS232 for service access, and MultiEthernet permits simultaneous EtherCAT, SERCOS III, and PROFINET communication.

A D-Sub 15 female socket provides the primary feedback path with a differential HSF signal of 1.0 Vpp. The resolver channel operates at 4 kHz and is excited by 18.2 Vpp. Secondary feedback relies on EnDat 2.1 absolute protocols and uses a regulated 5.0 VDC supply with an input resistance of 120 Ω. The board does not include STO or SS1 safety functions, so those functions must be provided externally. This layout supports primary and secondary encoder connections on the same control section.
