Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-PB-EN1-EN2-MD2-S1-S-NN-FW control section for the CSH Advanced Controllers series. Installed in an IndraDrive stack, it acts as the logic core that links motion commands, encoder feedback, and machine-level I/O so that servo axes can be synchronized with external devices across an automation line. The module processes setpoints, supervises safety signals, and relays status data through PROFIBUS to programmable controllers that govern packaging, printing, or material-handling equipment.

The analog front end accepts command voltages through an input resistance of 160 kΩ, limiting source loading and noise pickup. For actuator feedback, each voltage channel is digitized with a step size of 19.5 mV/inc. Output torque and velocity corrections are refreshed every 125 µs, which is fast enough for high-dynamic servo loops. Encoder 1 uses a Resolver or HSF interface powered at 8 V, and an auxiliary SSI encoder and digital I/O header provide secondary feedback connections. The fieldbus side uses PROFIBUS and connects through a D-Sub 9-pin female connector, while parameters can be accessed locally on a single-line display control panel. Two independent voltage channels leave the board as 2 analog outputs for speed or pressure references sent to external actuators.

Discrete signaling is handled on the MD2 expansion where the controller offers 16 digital inputs for sensor states and 16 digital outputs for coil or lamp actuation. Encoder 2 can use EnDat 2.1, 1 Vpp, or 5 V TTL feedback, and its supply rail is stabilized at 5 V to suit modern absolute transducers. A Form-C relay rated at 24 VDC 1 A is available for fault or ready contacts, isolating control logic from plant voltage. Safety Technology I/O is integrated so that drives can execute certified STO and safe limit functions without extra hardware.
