Product Description:

The CSH01.1C-SE-ENS-MEM-NNN-S1-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Intended for IndraDrive modular drives, it manages motion-control functions, analog and encoder interfaces, and integrated safety I/O within the drive system. By executing position and velocity loops internally, it reduces processing demand on the power section and supports multi-axis coordination over an optical SERCOS ring in production machinery and material-handling lines. Its role is to provide the control functions needed for precise axis operation while remaining separate from the main power electronics.

Its analog section accepts ±10 V references. An input bandwidth of 1.4 kHz lets the module follow rapid command changes, while an input resistance of 160 kΩ keeps sensor loading low. The 16-bit converter provides a resolution of 1.23 mV/inc, supporting fine setpoint adjustment. On the output side, the digital-to-analog stage provides up to 5 V / 1 mA, and each step is quantized at 19.5 mV/inc for repeatable feedback or trim signals. Encoder inputs accept 1 Vpp, HIPERFACE, EnDat 2.1, and 5 V TTL formats, and the card can also generate incremental or SSI absolute signals. A 12 V supply is available for external sensors, and the SERCOS II port provides deterministic drive communication between the controller and connected system components.

High-speed bus traffic is sustained at up to 16 MBaud, keeping update cycles short when many parameters are exchanged. With encoder emulation active, the card delivers pulse streams at 1 MHz that remain accurate over a cable length of 40 m, allowing remote devices to mirror axis position without a separate feedback source. Safety Technology I/O is built in, and dual-channel inputs accept 24 V signals at 3 mA while the internal supply can source 1.6 A for light curtains or switches. An onboard relay rated at 24 V / 1 A provides a hardwired STO or emergency-stop channel to remove torque if fieldbus control is lost.
