Product Description:

The CSH01.1C-PB-ENS-EN2-MEM-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It is installed in IndraDrive power units to command one servo axis, process local I/O, and exchange data with higher-level PLCs. By combining motion logic, encoder processing, and fieldbus communication on a single plug-in card, the unit streamlines axis management in packaging lines, material-handling stations, and other automated equipment.

This module is rated for a single-axis configuration, so all control resources are dedicated to one drive channel without internal time-sharing. For cell-level networking, it supports the PROFIBUS fieldbus, allowing cyclic position setpoints and diagnostic words to traverse the backplane at deterministic intervals. A legacy RS232 port is available for service access, diagnostics, or initial parameter cloning. Program and parameter files are stored on a removable MultiMediaCard, which allows convenient data storage and transfer between compatible units. The primary encoder socket accepts feedback from IndraDyn Motors using the Hiperface® protocol, enabling absolute position capture after power-up without homing.

Local signal handling is addressed through the card’s integrated analog and digital I/O, eliminating the need for separate terminal extenders on compact machines. A dedicated Relay output can trigger motor contactors or brake solenoids directly from control events. Option 3 activates Encoder Emulation, meaning it can synthesize incremental tracks for older CNC or robot controllers that lack serial feedback decoders. Secondary feedback acceptance is realized through the EnDat 2.1 interface, which also supports 1 Vpp and 5 V TTL signals for dual-loop accuracy in gantry or tension-control applications.
