Product Description:

The CSH01.1C-S3-ENS-NNN-MD2-S1-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Serving as a plug-in module for IndraDrive power units, the card supervises motion sequences, exchanges data with higher-level PLCs, and converts encoder feedback into position values. Its role in industrial automation is to coordinate multiple drives and peripheral sensors so that packaging, machining, and material-handling stations maintain repeatable speed and position accuracy under changing loads. Because it is the control section rather than the power stage, it concentrates on signal handling, axis coordination, and command execution inside the drive assembly.

This controller accepts incremental inputs up to 400 kHz at 5 V TTL level, enabling high-resolution position capture from fast encoders. Two analog monitor channels issue command voltages with a granularity of 19.5 mV/inc, which supports precise adjustment of proportional valves or external amplifiers. Network traffic is routed over a 100Base-TX Ethernet segment through a dedicated RJ-45, 8-pin jack, while cyclic setpoint exchange with drive axes runs on the SERCOS III control bus. Inside the card, position values are widened by a 12-bit converter so quadrature or sine-cosine signals are normalized before internal processing. The asynchronous service port supports RS-232 communication up to 115 kBaud, allowing local setup without interrupting the real-time fieldbus.

The MD2 expansion provides 16 discrete inputs and 16 sourcing outputs, and each output can deliver up to 0.5 A for solenoids or tower lights. Differential encoder lines use a termination of 120 ohms, and the sensor supply rail is maintained at 11.6 VDC for connected feedback devices. RS-232 communication remains reliable with cable runs as long as 15 m, which is useful when the controller is mounted deep inside a cabinet. Power-up events are limited by a typical 4 A inrush during a 100 ms pulse, and the nine-pole S1 connector provides access to service signals for diagnostics and support functions.
