Product Description:

The CSH01.1C-ET-ENS-EN1-MA1-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It installs in modular drive racks, where it handles command processing, analog I/O, and network routing for connected drive components. This arrangement allows multiple servo axes to operate in step inside automated machinery and material-handling cells. The control section also supports coordinated motion tasks in applications that require stable communication between field devices, feedback elements, and the higher-level controller.

This unit offers 2 analog input channels that track process variables through a high input resistance of 1000 kΩ, minimizing sensor loading. Each input is digitized at 12-bit depth, allowing fine signal conversion for closed-loop calculations. Two analog outputs can source up to 10 mA per channel, and they use the same conversion depth for smooth reference generation to external actuators. The base electronics draw only 7.5 W, which helps limit heat buildup inside compact cabinets. For position feedback, Encoder 1 is supplied with 12 V and accepts IndraDyn, Hiperface, or 1 Vpp sine-cosine signals, allowing the module to work with several common feedback formats used in motion systems.

Additional encoder support is provided by an 8 V supply that powers resolver or HSF devices, allowing mixed-feedback installations without auxiliary converters. Multi-Ethernet communication is implemented on a 100Base-TX interface that terminates on an RJ-45 8-pin connector, giving the unit a standard copper network link for control data exchange. That connection may be extended to 100 m for remote drive cabinets while maintaining rated bandwidth. Serial diagnostics remain available through an RS-232 port, which is useful when direct local access is preferred for status review, parameter checks, or basic troubleshooting during system setup and service.
