Product Description:

The CSH01.1C-ET-EN1-NNN-MEM-L1-S-NN-FW is a controller module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed for multi-axis drive systems, the device receives position data, converts it for various feedback topologies, and forwards motion commands to connected inverters. Its role in industrial automation is to serve as the interface between servo hardware and plant-level PLCs, providing real-time synchronization while reducing the need for separate gateway hardware.

Communication with higher-level networks is handled through the Multi-Ethernet port set, allowing the use of standard industrial protocols without changing hardware. Absolute position data leaving the card follow the SSI format, and incremental channels can switch at up to 1 MHz, which is suitable for high-resolution feedback loops. The acknowledgment potential for safety and power-good monitoring is supplied at DC 24 V / 1 A, while the EN1 auxiliary encoder rail operates from a separate 8 V source. Encoder emulation can produce absolute and incremental outputs at the same time, and both signals are galvanically isolated to help prevent ground loops. A resolver and HSF input are available on the encoder interface, and status values are shown on a standard single-line control panel at the front of the module.

For downstream counting electronics, incremental signals can be routed over cables up to 40 m. Serial diagnostics rely on an RS-232 link rated for 15 m and peak throughput of 115 kBaud. Safety wiring terminates on a D-Sub, 9-Pin Female connector, and the integrated safety technology uses Starting Lockout to disable drive enable until external conditions are met. The lockout channel monitors a 24 V, 3 mA signal, and the galvanically isolated architecture helps limit interference between connected circuits.
