Product Description:

The CSH01.3C-NN-ENS-MEM-CCD-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive stack, it serves as the command processor that links motion profiles with field feedback. The unit receives position data through an IndraDyn, Hiperface, 1 Vpp, or TTL encoder interface, replicates both absolute and incremental formats for downstream devices, and exchanges status information on an Ethernet-based master bus. Its RS232 port and additional Ethernet engineering interface allow parameterization and diagnostics without interrupting real-time communication.

The analog front end is tuned for signal quality. Each input has a high input impedance of 160 kohm, which minimizes sensor loading, and accepts bipolar signals within a ±10 V window so differential process values can be captured directly. For actuation, the board provides 2 analog output channels, and each channel sources up to 1 mA at a fixed reference of 5 V. Four combined I/O lines supplement these analog resources, and relay contacts rated 24 VDC at 1 A can switch interlocks that draw more current than the semiconductor outputs can carry.

Discrete signaling is handled by 7 dedicated digital inputs that capture limit switches or emergency stop contacts with deterministic latency. Cabinet layout is simplified because the module is only 241 mm tall and 49.5 mm wide, so multiple axes can be grouped tightly on a DIN rail. The integrated safety channel provides Safe Torque Off, which inhibits the drive power stage without affecting fieldbus communication when it is triggered. Ethernet cross-communication keeps motion groups synchronized, while encoder emulation outputs provide coherent position references for legacy drives.
