Product Description:

The CSH01.1C-PL-EN2-MEM-MA1-S1-S-NN-FW controller belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. Intended for single-axis IndraDrive assemblies, the board converts process commands into real-time drive signals so that a connected servo motor can move precisely along a programmed profile. By combining motion computation, encoder feedback handling, and integrated safety terminals on one module, it supports compact machine layouts in automated transfer lines, filling systems, and other equipment that requires coordinated acceleration, velocity, and position control.

It offers two differential analog input channels that receive a ±10 V process signal from external sensors, and differential wiring reduces common-mode noise when the cabinet ground differs from field references. Each input and the accompanying two analog outputs operate over the same range, so the controller can both read and generate standardized motion references. Conversion resolution is 12-bit, allowing 4096 discrete steps that refine velocity or pressure settings without noticeable quantization. For direct encoder connection, the board provides a port that accepts EnDat 2.1 / 1 Vpp / 5 V TTL signals, and automatic format detection helps the controller recognize compatible feedback types. The internal emulation track is galvanically isolated, preventing ground-loop currents from transferring between the drive bus and field devices.

Because it is a single-axis unit, configuration focuses on one drive channel, which reduces parameter lists and speeds diagnostics. Command data enter through a parallel interface, a hardware path chosen for deterministic timing when PLC scan delays must be minimized. Safety functions are processed locally by the board’s safety technology I/O section, and the designated output line can switch loads up to 24 V / 0.5 A so an external relay or valve can be de-energized in less than one cycle. This arrangement lets the controller process sensor input, manage feedback, and issue motion commands within a compact single-drive platform.
