Product Description:

The CSH01.1C-S3-EN1-NNN-NNN-L1-S-NN-FW motion logic module is a single-axis control unit manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power section, it issues position, velocity, and current commands so field devices remain synchronized with the plant sequence. The module links digital drives, encoders, and safety I/O, acting as the supervisory element that translates higher-level PLC tasks into deterministic axis movements needed in industrial automation cells.

On the analog side, one input is present and its circuitry presents 160 kΩ of resistance, a value high enough to avoid loading low-power sensors. The unit provides 2 analog outputs; each can source up to +1 mA or drive reference signals as high as +5 V, letting the controller hand off speed or torque commands to legacy amplifiers. For mixed-signal tasks, the board also provides 4 digital I/Os, and every digital output line can deliver 500 mA to support small relays or optocouplers without an external booster. Incoming digital inputs recognize a logic-high level once 15 V is applied, ensuring noise margins on long machine cables.

High-speed deterministic networking is handled by the SERCOS III master interface, giving cycle times that match the controller’s maximum internal switching rate of 16 kHz for current control. When diagnostics or parameter access are required, the integrated RS-232 port transmits at up to 115 kBaud over a cable length of 15 m. An internal relay with one normally open contact can be used for status signaling, and an HSF/RSF encoder option socket accepts high-resolution feedback. For personnel protection, the unit carries the certified Starting Lockout function, which keeps a hardware inhibit active until all safety conditions are met before power can reach the downstream drive.
