Product Description:

The CSH01.1C-SE-EN2-ENS-MEM-S2-S-NN-FW control section belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. This plug-in module serves as the central processing layer inside an IndraDrive cabinet, where it interprets encoder feedback and sends command values to the connected power inverter. It coordinates synchronized axis movement, speed regulation, and safety-related responses required in filling, cutting, and material-handling equipment. Because it is a control section rather than a power stage, it focuses on signal handling and drive coordination instead of direct motor current generation.

The analog interface accepts an input range of ±10 V, allowing external PLCs to send direct velocity or torque references to the controller. Its monitor output can source up to 1 mA, and the voltage on that channel is limited to 5 V, which helps protect connected measuring devices from excessive load. Fieldbus communication is handled through SERCOS II, providing fast optical data exchange and synchronized command timing between drives on the machine. Four high-side digital outputs can switch loads of up to 500 mA. Position feedback emulation is available in SSI format so upstream controls can receive absolute position data even when the motor uses a different encoder protocol. This arrangement lets the control section exchange motion data and local I/O signals without requiring an additional interface on basic machine layouts.

A dedicated secondary encoder port, EN2, supplies 350 mA at 5.0 V for sensors that use EnDat 2.1, 1 Vpp, or 5 V TTL signaling. A separate ENS channel provides the higher supply needed by IndraDyn or HIPERFACE transducers, while the Safe Motion option uses these feedback paths to monitor velocity and position without depending on the PLC. This split encoder support allows the module to work with different feedback types in mixed-axis systems. The optical ring can operate at up to 16 MBaud, which supports rapid data transfer even when multiple axes share the same communication link. The RS-232 maintenance port also supports cable runs of up to 15 m, allowing access from outside the enclosure when local diagnostics are needed.
