Product Description:

The CSH01.1C-S3-ENS-MA1-MD1-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive systems, this unit coordinates servo axes, field devices, and integrated safety inside an automation cell. Acting as the central processing board, it exchanges real-time motion data with drives and higher-level PLCs to keep positioning loops synchronized. Because it serves as the main control layer, the module links axis supervision with the local interface options installed on the drive.

At the board level, the controller draws only 7.5 W, so panel heat rise is minimal. Motion commands and diagnostics are carried over the SERCOS III interface, which permits deterministic cycle times between connected devices. An integrated encoder socket supplies up to 500 mA at 11.6 VDC, which is sufficient for typical SinCos and Hiperface feedback heads. The MA1 module provides two differential analog inputs and two analog outputs, and both directions span ±10 V. Signal precision is held to 12-bit resolution, so velocity or torque references can be scaled without noticeable quantization. The analog section can accept external reference signals and return processed values to companion hardware.

Discrete control is handled by the MD1 layer, which includes 12 digital inputs and 8 digital outputs that latch states within drive-synchronous scan cycles. Parameterization and service access are available through the RS-232 port at up to 115 kBaud, while network wiring enters through an 8-pin RJ-45 jack assigned to the S3 channel. For stop-category safety, the board implements Safe Torque Off, and its dual-channel logic is routed to a 9-pin female D-Sub connector for interlock wiring to contactors or a safety PLC. This arrangement keeps discrete control, serial access, and safety signaling available on the control section without interfering with motion-bus communication.
