Product Description:

The CSH01.1C-SE-ENS-EN2-MA1-NN-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive inverters, it provides the main processing and communication functions that synchronize servo axes, collect field data, and execute motion commands in industrial automation cells. It serves as the control layer inside the drive and handles the signal paths needed for coordinated motion, status exchange, and feedback evaluation. By combining real-time bus communication with onboard analog and encoder channels, the control section supports precise axis coordination without requiring a separate standalone controller.

At only 49.5 mm wide, 241 mm high, and 103 mm deep, the module fits narrow drive stacks while still leaving room for cabinet ventilation. This compact format suits dense multi-axis layouts where several drive components must be mounted side by side in limited panel space. The master communication port uses the SERCOS fiber-optic interface, so deterministic cycle times can be maintained across multiple drives and synchronized motion tasks. Two differential analog inputs provide 2 differential measurement channels and accept ±10 V signals for parameter adjustments or external setpoints. The front panel includes a single-line display for basic status information, and safety functions must be handled by external devices because the unit does not include integrated safety technology.

Two analog output channels allow drive or valve control, and each channel has 12 bits of conversion accuracy. The permissible output swing is ±10 V, which matches the input range for straightforward signal scaling and signal exchange with compatible external devices. For position feedback, the first encoder port supports IndraDyn / Hiperface / 1 Vpp / TTL, while the second supports EnDat 2.1 / 1 Vpp / TTL, allowing the drive to work with absolute or incremental encoders on separate 12 V and 5 V supply rails. This combination of analog channels and dual-protocol encoder links supports closed-loop motion tasks that require coordinated velocity and position control across interconnected axes.
