Product Description:
The CSH01.1C-NN-EN1-NNN-MEM-L1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power unit, it executes motion commands, supervises feedback devices, and distributes analog or serial signals so that servo axes follow programmed profiles in automated machinery. By combining drive regulation, I/O processing, and functional safety on a 49.5 mm-wide card, the module serves as the central logic layer between a higher-level PLC and the motor power stage.
The controller supplies two independent analog input channels that accept a differential range of ±10 V. Each input presents an impedance of 160 kΩ, allowing connection to high-impedance sensors without loading them. For actuation, the control section has 2 voltage outputs that operate across 0 to 5 V and can drive receiving circuits of at least 5 kΩ. The HSF / RSF encoder interface in Option 1 supports high-speed SinCos feedback, while Option 3 operates as an encoder emulator so legacy position controllers can read a synthesized signal. Physical dimensions of 49.5 mm width, 241 mm height, and 103 mm depth match the standard single-slot format inside Rexroth drive stacks.
Serial diagnostics are provided through an asynchronous channel that transfers data between 9.6 to 115 kbaud and may be cabled up to 15 m without repeaters. During power-up, the drive section draws a typical inrush of 4 A, and its rapid-response inputs can accept pulses down to 100 ms, enabling edge-triggered functions such as starting lockout release. The integrated starting lockout is the designated safety option, and it prevents unintended energizing of the power stage until all prerequisites are met. The Master Communication slot is not equipped, so higher-level fieldbus traffic must be handled by the associated power module or by an external PLC. The control section uses passive cooling, which allows it to operate without a dedicated fan on the card.
