Product Description:

The CSH01.1C-ET-ENS-EN2-MEM-L2-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed on the IndraDrive platform, this module supervises servo axes, machine I/O, and field networking from a single plug-in slot. Its role in industrial automation is to execute motion sequences deterministically, translate process variables into drive commands, and forward diagnostic data so that packaging, handling, or assembly equipment maintains repeatable cycle times. This arrangement allows one control section to coordinate axis behavior and communication tasks without requiring separate standalone control hardware in the same drive position.

Two differential analog inputs present a high input resistance of 160 kΩ, which minimizes loading on connected process transmitters, and the A/D converter resolves changes down to 1.23 mV/inc. Command outputs drive reference lines across loads of 5 kΩ, and the D/A converter uses a granularity of 19.5 mV/inc; sustained sourcing is limited to 1 mA. The controller draws only 7.5 W from the backplane, while startup transients must still be considered because a typical inrush of 4 A occurs and the pulse width remains under 100 ms. These values help maintain stable analog interfacing and support predictable power distribution when the drive is energized.

Logic transistors can deliver up to 500 mA, and an onboard relay switches loads up to DC 24 V / 1 A when galvanic isolation is required. Feedback port EN2 supports sense wiring runs of 75 m, while the MEM service bus accommodates 40 m between stations to help with cabinet layout over longer panel distances. Ethernet communication follows the IEEE 802.3u clause set and uses 100Base-TX signaling, and copper segments may span 100 m without repeaters. The ENS rail supplies 11.6 V to position encoders, and the stated output limits support stable operation when feedback devices, relay functions, and network traffic are active at the same time.
