Product Description:

Bosch Rexroth Indramat builds the CSH01.1C-ET-EN2-EN2-MA1-NN-S-NN-FW as part of the CSH Advanced Controllers series. This control section is intended for drive-based automation where a compact module must route fieldbus traffic, handle encoder feedback, and process small-signal analog channels. By combining communication, motion feedback, and low-level I/O on one board, the unit simplifies cabinet layouts and shortens signal paths between the drive and the higher-level PLC. This arrangement supports coordinated machine functions without requiring separate interface cards for each signal type.

The controller links to plant networks through its Multi-Ethernet interface, providing a single port that can be configured for several industrial Ethernet variants without hardware changes. Its digital outputs can source up to 500 mA, which is enough to actuate relays or LED signal towers directly. Position feedback is accepted on two independent channels that support 2x EnDat 2.1 / 1 Vpp / 5 V TTL, allowing mixed use of incremental and absolute encoders. Internal electronics draw only 2.2 W from the embedded ET supply, which helps keep the electrical load on the drive low. The MA1 analog input accepts signals within a range of ±10 V, allowing direct connection of speed or torque reference voltages from external motion controllers.

An input impedance of 1000 kΩ on the MA1 channel minimizes loading on upstream sensors, helping preserve signal accuracy. Its complementary output can source up to 10 mA for analog control loops or recorder feeds, and an onboard relay handles up to DC 24 V / 1 A for binary control functions such as interlocking contactors or brakes. Diagnostic tasks are performed over the RS232 port, which reaches a maximum rate of 115 kBaud for serial data exchange. This combination of analog, relay, encoder, and network functions makes the control section suitable for compact motion systems that need several interface types in one drive assembly.
