Product Description:
The CSH01.1C-NN-EN1-NNN-MEM-L2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted on a compatible power section, it governs servo and spindle axes, handles field I/O, and manages integrated safety functions inside automated assembly lines, packaging stations, and machining centers. By combining analog conversion, encoder capture, and resolver evaluation on one board, the device issues deterministic motion commands that synchronize multiple drive modules in real time. This integrated layout reduces the need for separate interface hardware and keeps motion-related processing within the same control platform.
Analog performance starts with an input resistance of 160 kΩ, which keeps sensor loading minimal. Each incoming voltage change is detected in steps of 1.23 mV/inc, while output references leave the section with a granularity of 19.5 mV/inc. The base board dissipates only 7.5 W, and the plug-in EN1 communication module adds another 6 W, so cabinet thermal loading remains low. Internal rails deliver 250 mA at 8 V to HSF circuitry, eliminating the need for an external sensor supply. During signal processing, the controller limits generated pulses to 100 ms, which helps prevent dwell times that could overheat downstream amplifiers. This combination supports accurate reference handling and stable signal conversion in closed-loop control.
The MEM encoder channel can source 20 mA per track, maintains reliable signaling over cables up to 40 m, and sustains edge rates at 1 MHz; a dedicated 2 W MEM board powers this interface. Resolver inputs receive a 4 kHz excitation at 18.2 Vpp, ensuring clean sine-cosine amplitudes for precise angle computation. On power-up, the controller draws an inrush of 4 A, after which steady operation continues within nominal limits, and its safe-torque-off acknowledgment contact handles 1 A to interface directly with external safety relays. This arrangement supports both encoder-based and resolver-based feedback without requiring separate evaluation hardware elsewhere in the cabinet.
