Product Description:

The CSH01.1C-CO-ENS-EN2-MD2-NN-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It is a multi-module control unit intended to coordinate servo drives, field I/O, and higher-level networks in industrial automation cells. By combining CANopen and DeviceNet interfaces with dedicated encoder and motion expansion slots, the device serves as the central command layer that links motion tasks to plant-wide communication buses.

Stable operation begins with a control supply of DC 24 V fed through an input stage that can tolerate a typical inrush of 4 A. Once energized, the controller draws a base power of only 7.5 W, which helps limit demand on cabinet power distribution. Individual plug-in sections add limited overhead: the CO communication module requires 1 W, the EN2 encoder module needs 6 W, and the MD2 measurement module adds another 1 W. Current delivery is also divided by function, with the EN2 outputs supplying 350 mA for incremental sensors while the MD2 SSI interface provides 0.2 A for absolute transducers. These values help with power planning and support proper cable selection where voltage drop must be controlled.

On the signal side, the integrated digital outputs can source up to 500 mA per channel with a maximum pulse width of 100 ms, making them suitable for fast valve actuation or status lamps. The EN2 sense line stabilizes feedback electronics at 5.0 V, and the ENS auxiliary rail delivers 11.6 V with its own 500 mA budget for proximity switches. Serial diagnostics are available through an RS-232 port that reaches 115 kBaud for data transfer and setup tasks. For real-time machine communication, the CANopen and DeviceNet links use deterministic arbitration so multiple drives can be synchronized with minimal timing variation. The MD2 section also mirrors field voltage with a 24 VDC SSI source so absolute encoders can operate reliably across longer cable runs.
