Product Description:
The CSH01.1C-PB-EN1-EN2-MD1-NN-S-NN-FW is a control section from Bosch Rexroth Indramat in the CSH Advanced Controllers series. Installed in an IndraDrive rack, it supervises axis motion, relays fieldbus traffic, and provides local diagnostics through its single-line display. Within an automation cell, it acts as the intermediary that translates plant-level commands into real-time drive signals, allowing coordinated positioning and process sequencing. This arrangement lets the drive system combine communication, diagnostics, and motion control within one compact control layer. Its role is especially useful in multi-axis equipment where communication timing and drive response must stay closely coordinated during operation.
The module’s primary control bus is PROFIBUS, carried over differential lines that follow EIA-RS485 signaling. A maximum rate of 12 MBaud supports fast telegram cycles when multiple drives share the segment. For service access, a front-panel RJ-45 socket offers a 100Base-TX port so setup data can be transferred without disturbing normal network operation. Twelve additional digital inputs and eight digital outputs can be enabled through the dedicated expansion connector, letting the controller read limit switches or actuate relays without an external PLC card. Resolver or HSF feedback is supplied at 8 V, allowing direct connection of analog rotor position devices while maintaining the noise immunity needed for high-speed motion loops.
A separate encoder channel provides a 5 V rail for incremental or absolute transducers, including the serial protocol EnDat 2.1 used for fine position data. When the application needs velocity or torque reference signals, the onboard DAC issues commands with 8-bit depth, and each increment corresponds to 19.5 mV/inc, which makes analog scaling straightforward. The analog stage can also be disabled when that function is not required. In that configuration, external safety devices can handle protective functions while the controller remains focused on deterministic motion and expanded digital I/O.
