Product Description:

The CSH01.1C-ET-EN2-MEM-MA1-S2-S-NN-FW drive controller is supplied by Bosch Rexroth Indramat within the CSH Advanced Controllers series. In multi-axis motion systems, this control section handles servo regulation, fieldbus communication, and safety monitoring for the associated power modules. By placing PLC-class processing and encoder feedback conversion in the same housing, the part streamlines cabinet layout and shortens cycle times in industrial automation cells such as gantries, packaging lines, and robots.

The controller provides local analog expansion so the drive can interact with external process signals. A combined I/O converter digitizes feedback at 12 bit resolution, yielding step sizes suitable for temperature or pressure loops. Two differential inputs are available, so the unit offers 2 analog input channels for sensors requiring voltage or current scaling. Each of the dual outputs can drive loads with a burden up to 1 kΩ, allowing control of actuators such as proportional valves. During power-up, the electronics draw a surge of 4 A, and once the capacitors are charged, continuous demand falls to 7.5 W, which helps reduce cabinet thermal loading.

High-speed position reference generation is handled by an emulation port that streams pulses at 1 MHz, which covers fine-pitch linear scales without external multipliers. The same header supplies absolute or incremental data through an EnDat 2.1 / 1 Vpp / 5 V TTL interface, with the sensor rail delivering up to 350 mA at 5 VDC for encoder support. All logic boards operate from a common backplane fed with 24 VDC, and the design confines the initial charge impulse to a 100 ms window to minimize fuse stress. Safe Motion technology supervises STO, SS1, and other safety modes, while a Form-C relay able to switch 1 A circuits is provided for ancillary interlocks. Multi-Ethernet connectivity links the controller to EtherNet/IP, PROFINET RT, and EtherCAT drives without additional gateways.
