Product Description:
The CSH01.1C-SE-EN1-EN2-MD1-L2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power module, it provides axis-level command processing and signal conversion. It also manages network communication so that servo drives based on MHD or MKD motors can be coordinated within industrial automation lines.
This module accepts two differential analog feedback channels with an input impedance of 160 kΩ, allowing high-source-resistance sensors to interface without loading errors. Each analog output can source or sink up to 5 V / 1 mA, and position or speed commands leave the converter at a granularity of 19.5 mV per increment, matching typical 10-bit process images. Eight transistor outputs on the MD1 terminal block switch loads drawing as much as 500 mA, while twelve digital inputs share the same connector for feedback states. The controller energizes these field circuits with an internal I/O rail that delivers 1.1 A of 24 V DC. Relay contacts rated at DC 24 V / 1 A are provided for galvanically isolated signaling, and the STO request line draws only 24 V / 3 mA to trigger the safety logic.
Total draw from the control supply remains below 24.5 W, reducing cabinet heat when multiple sections are stacked. Motion commands and real-time feedback are exchanged over the SERCOS II control bus, while parameterization or diagnostics can be performed locally through a RS-232 service port. Encoder channel 1 supports the absolute and incremental formats used by MHD and MKD machines, and channel 2 accepts EnDat 2.1, 1 Vpp sine-cosine, or 5 V TTL signals so both legacy and high-resolution transducers can be connected simultaneously. The integrated safety circuit fulfills the Safe Torque Off function, and acknowledgment contacts are rated for DC 24 V / 1 A to allow direct wiring to emergency-stop relays without auxiliary interposing hardware.
