Product Description:

The CSH01.2C-PB-ENS-EN1-CCD-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into an IndraDrive power module and supplies motion logic for one drive channel, translating PLC tasks into real-time current, velocity, or position commands. In automated machinery, the card forms the interface between fieldbus data and the inverter stage, enabling precise servo regulation without the need for a separate standalone PLC. This arrangement keeps the motion control functions close to the power stage, which supports fast response during axis operation.

The controller is classified as Advanced, which indicates support for coordinated interpolation and fast PLC cycle times. Analog and digital I/O are integrated on the baseboard; the analog inputs accept signals up to 1.3 kHz, and each channel is digitized at 14-bit resolution for finer gain adjustment. A common-mode rejection of 50 dB helps attenuate ground noise so sensors remain accurate in electrically harsh panels. Because the hardware uses a single-axis configuration, its parameter set focuses on one motor. The integrated I/O also allows local sensors and reference signals to be processed directly by the controller instead of through extra interface hardware. Cross communication is available, permitting position data exchange with neighboring drive sections without occupying the main fieldbus.

Field connectivity is handled through PROFIBUS for cyclic control data, while service tasks use the RS232 serial port. Parameter sets can be transferred through a MultiMediaCard, which allows local data handling without a programming laptop. Encoder feedback from IndraDyn motors with Hiperface feedback is accepted on the primary port, and a secondary interface supports MHD and MKD motor encoders for mixed installations. The secondary encoder interface is useful when a machine uses more than one motor family across different axes. An integrated relay output allows direct switching of external contactors, and the standard operator panel provides local status keys. The unit has no integrated safety technology, so external STO devices are required when that function is needed.
