Product Description:

The CSH01.1C-ET-ENS-EN1-EN2-NN-S-NN-FW is a modular motion-control processor built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive cabinet, it handles trajectory generation, feedback evaluation, and network traffic so that multiple servo axes respond in real time. By concentrating these tasks in one unit, the controller streamlines coordination between drives, sensors, and higher-level PLCs across a wide range of industrial automation systems.

In standby, the controller draws only 7.5 W, which minimizes panel heat and allows dense stacking of electronics. Control communication is handled through a Multi-Ethernet interface that automatically selects protocol stacks while maintaining physical compliance with 100Base-TX signaling. Two shielded RJ-45, 8-pin sockets are provided, and each port supports cable runs up to 100 m without repeaters. During power-up, the unit experiences a typical inrush of 4 A, so supply breakers and filters must be sized to tolerate that short surge. Diagnostic LEDs on the front panel report link status, frame errors, and activity so network traffic can be checked before operation.

Dedicated sensor headers supply encoder and resolver power directly from the controller. The EN1 interface furnishes 8 VDC for Hall sensor feeds and drives a resolver with a 4 kHz carrier at 18.2 Vpp AC, ensuring clean position data even with long-stroke motors. The ENS header delivers auxiliary power at 12 VDC and up to 500 mA, allowing touch probes or reference switches to be connected without separate supplies. For incremental encoders on EN2, the allowable cable length rises to 75 m when sense lines are used; without sense wiring, the limit is 50 m, preserving signal integrity across moving gantry or conveyor installations.
