Product Description:

The CSH01.3C-ET-ENS-EN2-CCD-L2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular drive racks, it coordinates motion axes by converting fieldbus commands into precise analog and encoder-based feedback signals. The module manages velocity, position, and diagnostic data while occupying minimal panel space inside an IndraDrive cabinet. Because it serves as the control section rather than the power stage, it focuses on signal handling, drive coordination, and interface functions for the connected axes.

An analog input resolution of 1.23 mV/Inc allows fine voltage sampling for process variables, and the output resolution of 19.5 mV/Inc provides comparable granularity when the controller drives external actuators. Its control electronics dissipate only 8.5 W, which helps limit additional heat inside the cabinet. Parameters are accessed through a compact Single-Line Display control panel, allowing local status review and setup. On the communication side, cross-drive coordination is handled by the IEEE 802.3 Master interface, while the primary network layer is Multi-Ethernet over a 100Base-TX link. Encoder 1 resources include a maximum steady current of 500 mA, a 400 kHz square-wave bandwidth, and an 11.6 VDC sensor supply for reliable high-resolution position capture on the first axis.

For the secondary channel, Encoder 2 can source 350 mA and accepts square-wave signals up to 1000 kHz. It also furnishes a sense-line supply of 5.0 VDC to reduce voltage drop errors on longer cables. The separate second encoder channel allows an additional feedback source to be processed without an external interface module. Functional safety is embedded through the Safe Torque Off feature, which removes drive power without affecting the control logic. STO wiring is implemented on a D-Sub 9-Pin connector and responds to a 24 VDC input level.
