Product Description:
The CSH01.1C-S3-EN2-EN2-MD2-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It slots into an IndraDrive power stage and delivers axis regulation, fieldbus exchange, and encoder evaluation for servo systems used in packaging machines, handling modules, and general automation lines. By integrating analog I/O, digital I/O, and dual-channel encoder feedback, the unit replaces separate PLC motion cards and simplifies cabinet wiring. This arrangement allows one drive-mounted module to process commands, feedback, and local signals without additional motion hardware in the cabinet.
An analog input resistance of 160 kΩ limits current draw from connected sensors, while the analog output stage updates every 10 µs with a granularity of 19.5 mV/incr. The controller’s base power consumption is only 7.5 W, so heat generation inside the drive rack remains low. Motion and diagnostic data are exchanged over Sercos III, ensuring deterministic timing across multiple axes. For the En2 motor feedback supply, the channel supports a load resistance down to 35 Ω and can source up to 350 mA to absolute encoders. Primary and secondary interfaces accept EnDat 2.1, 1 Vpp, or 5 V TTL signals, allowing redundant position tracking. The option-3 mezzanine provides digital I/O with SSI, extending the base 16 Md2 inputs and 16 Md2 outputs without requiring an external coupler. A relay contact is included for auxiliary switching tasks.
The En2 supply line is held at 5.0 V with sense conductors to compensate for cable losses. An SSI transducer can draw up to 0.2 A across runs as long as 40 m at 1 MHz, which supports longer encoder cabling within the machine. A relay contact is available for auxiliary switching of brakes or contactors. The controller supports coordinated motion, homing, and safety interlocks in a compact drive-mounted format.
