Product Description:
The Bosch Rexroth Indramat CSH Advanced Controllers series includes the CSH01.1C-S3-ENS-NNM-NNN-L2-S-NN-FW motion control card. This controller module is intended for multi-axis drive systems where it performs real-time processing of position, velocity, and torque commands. Within an automation rack, it acts as the central command layer, translating fieldbus data into drive-ready signals so that servo inverters can execute coordinated motion sequences on production machinery. That role allows multiple connected axes to follow shared timing and synchronized path commands during machine operation.
Two differential analog input channels accept signals with an analog input bandwidth of 1.4 kHz. This allows the controller to process rapidly changing reference signals without excessive attenuation. Each input presents 160 kΩ of resistance to the source, so PLC or sensor stages see minimal loading. On the output side, the module drives reference voltages into loads no lower than 5 kΩ, and its digital-to-analog converter updates at a granularity of 19.5 mV/inc, allowing fine scaling of speed or torque commands. Eight digital outputs are rated for a continuous sink current of 500 mA, which is suitable for actuating contactors or indicator lamps. A form-C relay is available for galvanically isolated switching, and its contacts are rated for 24 VDC at 1 A.
The communication backplane relies on a 100Base-TX physical layer, and packets leave the board through an 8-pin RJ-45 socket that links the controller to higher-level networks. Application data is exchanged over the SERCOS III protocol, while a secondary RS-232 maintenance port supports command strings up to 115 kBaud. The separate maintenance port allows direct service access without using the real-time motion network. An ENS encoder interface is fitted, with feedback wiring landing on a D-Sub 15 female connector, and the encoder is supplied with 11.6 VDC at 500 mA. Safe Torque Off circuitry is integrated, so drive power can be removed when safety chains open.
