Product Description:

The CSH01.1C-CO-ENS-EN2-MA1-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power unit, it handles interpolation, position loops, and network exchange for multiple servo axes. It synchronizes motion, collects feedback, and forwards status data to higher-level cell controllers, letting machine builders condense drive intelligence into one slot. Integration with the backplane cuts wiring and consolidates diagnostics in packaging, material-handling, and processing equipment. This arrangement keeps axis control close to the power stage and reduces the need for separate motion hardware elsewhere in the cabinet.

The control section supports several network and signal interfaces. The CAN interface supports up to 127 CANopen nodes, while the DeviceNet port maps as many as 64 DeviceNet nodes, allowing the controller to reside in either master or slave topologies. Sixteen digital channels are present, with each input rated at 24 V / 3 mA and each output switchable at 24 V / 0.5 A, so limit switches and contactors can be wired without relays. A diagnostic RS232 service socket operates at up to 115 kBaud, with a permitted cable length of 15 m for service computers. For precision analog generation, the MA1 module delivers an output resolution of 5 mV/inc, supporting fine torque or velocity commands. This combination lets the unit exchange commands with distributed devices while still handling local I/O directly.

The remaining interfaces handle encoder feedback and analog signaling. The EN2 encoder supply is 5 V and allows a 50 m cable when sense lines are absent or a reach of 75 m when sense conductors are used to correct voltage drop. Separate ENS excitation at 12 V powers resolvers and other single-turn sensors. Two MA1 analog inputs and two outputs are provided; the outputs source up to 10 mA, drive loads of 1 kΩ, and present a word width of 12 bit for each channel. These channels can interact with external reference devices and measurement signals without requiring separate analog interface hardware. The digital buses described earlier can forward processed setpoints while the analog and encoder ports close local feedback loops without external amplifiers.
