Product Description:

The CSH01.1C-ET-ENS-EN1-NNN-S2-S-NN-FW is a drive and motion control unit produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It acts as the command module that links feedback devices, fieldbus traffic, and power electronics so that servo axes respond accurately to PLC instructions in automated machinery. The controller handles signal processing and communication in one unit, which helps coordinated motion remain stable during positioning, speed control, and general axis management.

An input impedance of 160 kΩ on each analog channel minimizes loading on upstream sensors, while the 19-bit converter delivers an output step size of 19.5 mV/inc for fine voltage trimming of external amplifiers. Digital commands are recognized once the signal reaches 15 V, reducing the chance of false triggering when long cables introduce voltage drop. Each transistorized output can source up to 500 mA, and the combined current for all digital outputs is limited so internal heating remains controlled during simultaneous switching. During power-up, the module draws an inrush current of 4 A, so the supply must tolerate a short startup surge before normal operation begins. An analog load as low as 5 kΩ may be connected to every output without exceeding rated drive current, which supports direct interface to external control hardware.

Total internal dissipation is held to 7.5 W at the base operating level, and the dedicated Ethernet daughterboard adds only a small additional heat load for compact cabinet installation. The EN1 interface supplies sensors with 8 V at 250 mA and drives its resolver at 4 kHz, while the separate ENS port delivers 11.6 V with 500 mA for Hiperface encoders so mixed feedback types can operate on the same controller platform. System timing circuits permit a maximum command pulse of 100 ms, giving enough duration for relay control and other timed output functions. These electrical limits support reliable coordination of motion commands, encoder signals, and output control without requiring extra signal-conditioning modules in the cabinet.
