Product Description:

The CSH01.1C-PB-EN2-NNN-MD1-S1-S-NN-FW is a control section produced by Bosch Rexroth Indramat in the CSH Advanced Controllers series. When inserted into an IndraDrive power module, it supervises servo axes, processes sensor feedback, and forwards motion commands to actuators. It combines fieldbus communication, encoder evaluation, and user-programmable logic in one module. This arrangement supports coordinated positioning, speed regulation, and diagnostic reporting in industrial automation cells and transfer lines. In typical use, the control section handles the command side of the drive while the power module supplies motor current.

The module provides 2 analog voltage outputs for setpoints or diagnostic signals. Each channel completes digital-to-analog conversion in 10 µs, so real-time corrections can be issued within a standard position loop. This helps the controller send analog reference values with predictable timing during synchronized motion. Signal granularity is 19.5 mV/inc, and an 8-bit word length provides 256 discrete steps across the ±10 V span. Command and feedback data are exchanged with upper-level PLCs through the PROFIBUS master interface, allowing deterministic telegram scheduling in multi-axis installations.

The integrated MD1 board includes 12 digital inputs and 8 digital outputs; inputs switch reliably above 15 V, while outputs can source or sink up to 500 mA for contactor coils or indicator lamps. Encoder power is supplied by the EN2 line and is limited to 350 mA at a sensed 5.0 V to protect fine-pitch feedback cables. Position information is accepted through EnDat 2.1 / 1 Vpp / TTL signals, allowing absolute or incremental measurement without additional converter cards. A separate 5 V off-threshold helps prevent false triggering on noisy lines. The X10 slot supports digital I/O expansion, the 15 m RS232 service port supports setup and diagnostics, and the Safety Technology I/O layer supports category-based stop functions.
