Product Description:

The CSH01.1C-PB-EN1-MEM-MA1-NN-S-NN-FW module is an advanced motion controller from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. It serves as the central logic layer between higher-level automation equipment and servo drives, generating position and velocity commands while collecting feedback to maintain closed-loop accuracy in production lines and machine tools. It also passes control data between the machine controller and connected axes, which supports coordinated motion during normal operation.

Its analog front end accepts a command range of ±10 V, allowing proportional velocity or torque references to be read directly from PLC analog cards. Conversion accuracy is supported by a 12-bit resolution, which divides the full span into 4,096 discrete steps to reduce quantization error. Two independent feedback paths are available through 2 differential input channels, and the board mirrors processed values through two analog outputs for downstream devices. Digital host communication is handled via PROFIBUS, enabling deterministic cyclic data exchange with master stations. Physical signaling follows RS485 differential wiring, which supports stable communication over long network segments. This mix of analog and bus-based interfaces suits machines that combine conventional reference signals with networked control.

Complementing the analog and fieldbus interfaces, the module includes an encoder-emulation unit that issues reference pulses at 1 MHz. Because the emulation stage is galvanically isolated, these high-frequency signals remain protected from ground-loop effects when routed to external motion controllers. The EN1 slot provides a combined resolver and HSF interface, making the controller compatible with resolver sensors as well as high-speed feedback transducers; the interface supplies the transducer with 8 V excitation and operates at a resolver carrier of 4 kHz. Absolute and incremental formats are selectable so MKD, MKE, and MHD motor families can be integrated without additional converters. That combination is useful in mixed-system installations where different feedback types must be handled by the same controller. A single-line display assists with onboard diagnostics, and no integrated safety functions are included, so safety circuits must be external.
