Product Description:
The CSH01.1C-NN-ENS-EN2-NNN-NN-S-NN-FW is a motion-logic control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed to be installed in Rexroth modular drive stacks, this control section coordinates servo axes, gathers feedback, and interfaces with plant-level networks. By combining high-resolution analog channels, incremental encoder supplies, and serial diagnostics, the unit serves as the central processor that translates program commands into precise motor currents within industrial automation equipment such as packaging machines, assembly cells, and printing lines.
The analog front end supports a full-scale input span of ±10 V, allowing differential process signals to be sampled without external scaling. An input impedance of 160 kΩ helps keep transducer loading low. For actuation, the board provides a 5 V full-scale output that can feed reference inputs on external amplifiers, and loads as low as 5 kΩ are permitted without exceeding the driver limit. The step size is 19.5 mV/Incr, which allows fine control when trimming speed or torque loops. Discrete I/O terminals are energized from a 24 VDC rail, and each digital output channel can source 500 mA to lamps, relays, or small solenoids.
The module also delivers encoder power and serial diagnostics. EN2 supplies 5 VDC at 350 mA and supports cable runs up to 75 m when sense conductors compensate for voltage drop, allowing feedback devices to be mounted on more distant axes. The separate ENS channel provides 12 VDC at 500 mA for TTL encoders that pulse at frequencies up to 400 kHz, allowing high-speed incremental counting. Status and parameter data can be exchanged through an RS232 link that operates over 15 m of shielded cable while sustaining a throughput of 115 kBaud for data transfer and event logging.
