Product Description:

The CSH01.3C-PL-EN1-EN2-CCD-NN-S-NN-FW is a compact control section from Bosch Rexroth Indramat in the CSH Advanced Controllers series. Designed for IndraDrive servo platforms, the unit supplies the real-time logic required to synchronize multiple axes, process feedback, and exchange data with higher-level PLCs. By combining analog command channels, digital I/O, and network links on one card, it serves as the central motion coordinator inside packaging machines, robot cells, and material-processing stations. This arrangement allows one control section to handle axis coordination, signal processing, and communication tasks within a single drive platform.

Its command layer begins with an analog reference channel that accepts ±10 V, allowing the drive to follow speed or torque commands generated by external motion cards. The input is buffered by an impedance of 160 kOhm, which reduces loading on upstream electronics. For actuator feedback or cascade control, the module produces an analog reference signal of 5 V, 1 mA on its output pin. Real-time bus traffic between multiple IndraDrive axes is handled by the integrated Sercos III Master, which operates on the dedicated X24 and X25 cross-communication ports to distribute cyclic setpoints and status words. Resolver feedback on the primary encoder interface is supplied with 8 V, matching typical electromechanical transducers used on high-torque servo motors.

A second feedback path is available for optical or incremental encoders, and it supports EnDat2.1 / 1 Vpp / 5 V TTL formats with a stabilized 5 V sensor supply. For diagnostics, an Ethernet-Based X26 interface exposes parameters to standard software tools, while a separate RS232 port supports serial scripting and direct service access. Machine signals are wired through the parallel terminal block carrying 16 DI + 16 DO, and these channels are galvanically isolated to help prevent ground loops between field devices and the controller. A form-C relay rated at 24 VDC, 1 A is included for interlock duties such as drive enable or fault annunciation. The isolated I/O and service interfaces also support integration with mixed-signal machine layouts that combine sensors, actuators, and supervisory control hardware.
