Product Description:
The CSH01.1C-ET-ENS-EN2-MD2-S2-S-NN-FW is a single-axis motion controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It occupies a central role in drive automation by coordinating speed, position, and safety tasks for connected IndraDrive power sections. The unit draws its logic power from the control cabinet bus and exchanges process data through the integrated Multi-Ethernet interface, making it suitable for installations that combine standard Ethernet traffic with deterministic motion communication on one network.
This controller’s standby load on the 24 V supply is 7.5 W, so cabinet heat dissipation requirements remain low. For cold-start events, a peak inrush current of 4 A is permitted for up to 100 ms; sizing the upstream power supply to meet that short pulse helps prevent undervoltage faults. Once active, the MD2 extension provides up to 0.5 A to energize external sensors. Field wiring is connected through an 8-pin RJ-45 socket that follows the 100Base-TX standard, and link distances can be routed up to 100 m with Category 5e cabling. Additional screw terminals handle local I/O, while the synchronous serial interface supports absolute position feedback for legacy axes.
Two independent encoder channels are present. Channel 1 provides DC 12 V excitation and accepts IndraDyn, HIPERFACE, or analog 1 Vpp signals, whereas Channel 2 provides DC 5 V and handles EnDat 2.1, analog feedback, or 5 V TTL formats. For EnDat installations, the maximum cable length is 75 m when sense conductors are used, or 50 m without them. Option 3 adds support for 16 DI, 16 DO, SSI so that external actuators can be switched directly from the controller. Safe Motion technology supervises position-related safety functions, and the controller can be mounted in centrally located control cabinets while retaining reliable network timing.
