Product Description:
The CSH01.1C-SE-EN1-MEM-MA1-NN-S-NN-FW controller section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It acts as the central processing section in modular drive systems, coordinating motion axes and peripheral sensors by combining fieldbus communication, encoder handling, and discrete I/O resources. Installed inside IndraDrive power sections, this board manages positioning, speed, and torque loops for industrial automation machines.
Its network interface relies on SERCOS II, delivering synchronous telegram cycles for drive commands and status feedback. The board can source up to 500 mA on each digital output, enough to drive contactors or optically isolated relays without external amplifiers. The EN1 encoder connector supplies a regulated 8 V and has an input impedance of 10 kΩ, allowing direct connection of position transducers. For safety interlocks, the onboard relay carries up to 1 A at 30 V DC, so low-power circuits can be switched without auxiliary devices. High-speed capture of position data is supported by the MEM interface, which streams feedback with a maximum output frequency of 1 MHz for tight control at rapid cycle rates.
Signal quality is maintained over encoder leads because the MEM channel accepts cable runs up to 40 m without repeaters. For analog process values, the MA1 module offers two inputs and two outputs. Each output is trimmed in 5 mV steps, giving a resolution of 5 mV/inc, while the inputs reach a granularity of 1.23 mV/inc through the onboard converter. Filtering at the CPU front end is assisted by an input impedance of 160 kΩ, reducing loading on sensitive transducers. The controller can integrate resolver or HSF feedback, emulate absolute SSI as well as incremental signals, and use 1000 kΩ MA1 input paths with a range of industrial sensors without additional signal conditioners.
