Product Description:

The CSH01.1C-PB-ENS-EN2-MD1-S1-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive converter, it supervises servo axes, interprets encoder data, and exchanges commands with higher-level PLCs. Its role in industrial automation is to close the position and current loops internally, then send the resulting setpoints over the selected fieldbus so connected actuators respond in real time. Integrating these functions into a single plug-in card helps streamline machine design and reduce panel space requirements.

During operation, the card draws only 7.5 W from the backplane, while its logic electronics are powered by a 24 V DC control rail supplied by the converter. The current loop is refreshed every 125 µs, giving the drive the bandwidth needed for synchronized multi-axis motion. Two configurable analog channels provide 2 outputs at ±10 V for external actuators or diagnostic signals. Network integration is handled through PROFIBUS on a D-Sub 9-pin female connector, and the engineering port uses an RJ-45 100Base-TX interface for setup and service access. Motor position feedback is accepted through an IndraDyn, Hiperface, or 1 Vpp encoder input.

For discrete control, the optional extension board provides 12 In, 8 Out digital I/O points, and one normally open relay contact rated at 1 N/O can switch auxiliary loads. A safety channel supplies 24 V at 0.5 A for emergency stop logic, and at power-up the module can tolerate an inrush of 4 A for up to 100 ms before settling to normal consumption. Secondary serial diagnostics use a MiniDIN 8-pin RS-232 connector that supports cables up to 15 m in length. A second feedback socket accepts EnDat 2.1, 1 Vpp, and 5 V TTL encoders for redundant position monitoring.
