Product Description:

The CSH01.1C-SE-NNN-NNN-MA1-NN-S-NN-FW is a single-axis motion controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. This unit coordinates servo drives and connected sensors in distributed factory cells, translating fieldbus commands into precise position, velocity, and torque references. By combining analog I/O, serial diagnostics, and real-time fiber-optic networking, the controller functions as the central processing element in machine tools, packaging machines, and material-handling stations. It can manage coordinated motion where drive feedback, sensor states, and host commands must be processed with consistent timing across an automated line.

Its 2 analog input channels accept a ±10 V process signal. With a bandwidth of 1 kHz, they capture fast transducer changes, and each channel offers 12-bit resolution with 1000 kΩ input impedance to avoid loading sensitive sensors. Two analog outputs mirror reference variables over the same range and are rated for a 1 kΩ minimum load. Command and synchronization data flow through SERCOS II, a fiber-optic loop that aligns all axes with deterministic timing. The MA1 mezzanine draws 2 W for digital conditioning, and the SE expansion board adds another 2 W for communication support while keeping the added load on the backplane modest.

The controller’s logic rail demands 7.5 W from a 24 VDC supply and allows a start-up surge of 4 A, so the incoming power source must tolerate a brief inrush current. RS232 diagnostics reach cable lengths of 15 m and operate at up to 115 kBaud for parameter upload or trace capture. The serial service link separates diagnostic traffic from the motion network, which helps preserve deterministic communication during axis control. Separate mezzanine and expansion functions keep signal conditioning and communication tasks on dedicated hardware paths, which is useful in multi-axis racks that combine motion control, local sensing, and service access.
