Product Description:

The CSH01.1C-S3-ENS-NNN-NNN-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Designed for modular IndraDrive platforms, the unit serves as the motion and communication core between servo inverters and a plant-level PLC. It executes axis interpolation, handles diagnostic messages, and consolidates field data so that machine tools, packaging equipment, and automated assembly stations maintain deterministic positioning. The section plugs directly into the drive stack, minimizing wiring and conserving control cabinet space.

The housing measures 49.5 mm in width, 241 mm in height, and 103 mm in depth, giving clear limits for rack layout and airflow planning. A single-line display on the standard front panel shows status codes and parameter values without requiring an external HMI. Network traffic is passed through the integrated 100Base-TX port, while real-time axis data is exchanged over the master interface based on SERCOS III. Feedback from motors is accepted through IndraDyn, Hiperface, 1 Vpp, or TTL encoder channels, allowing mixed sensor types on one controller. During power-up, the module draws a typical inrush current of 4 A, which affects fuse sizing and supply cabling.

Functional safety is embedded through the Safe Torque Off circuit, which immediately disables drive power. The design carries a SIL3 / Cat. 3 PL e rating, allowing its use in machinery that requires a high safety level. The STO command reaches the board through a D-Sub 9-pin female safety connector, and acknowledgment is returned by a 24 V, 1 A contact while the control input uses 24 V at 3 mA. A dedicated RJ-45, 8-pin socket handles Sercos cabling. The motion inhibit can be sustained for a maximum pulse length of 100 ms, after which the controller re-arms according to its internal watchdog timing.
