Product Description:

The CSH01.3C-PL-EN2-NNN-CCD-L2-S-NN-FW controller is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It governs a single drive axis by accepting reference values, processing encoder feedback, and executing position loops that keep the motor aligned with machine commands. Within an automation cell, this module is installed next to the power section so the drive can receive real-time setpoints and safety states without additional gateway hardware.

The analog interface includes 1 x ±10 V input for velocity or torque references and 1 x 0 to 5 V, 1 mA output that can retransmit a conditioned process variable to external indicators. Position feedback is routed through the EN2, 5 V encoder channel that accepts EnDat 2.1, 1 Vpp, or 5 V-TTL signals, allowing high-resolution position control without format converters. Discrete machine states are handled by a parallel block that exposes 16 DI, 16 DO on the X15 37-pin connector, giving the PLC direct access to limit switches, sensors, and actuator coils. Vision or diagnostic devices can be attached to the CCD port, implemented as RJ-45, 100Base-TX, so image data or trace files move over standard Ethernet cabling without occupying the main fieldbus.

For host communication, the board retains a legacy channel over RS232, which supports setup through ASCII commands when Ethernet is unavailable. Functional safety is addressed through the integrated Safe Torque Off circuit on the X41 connector; when tripped, it removes drive-enable signals rather than relying on software. The housing height is 241 mm, the depth is 103 mm, and a single-line control panel on the front provides menu access without a laptop. DC auxiliaries from 19 V to 30 V at 1.1 A power the internal digital I/O logic, while two probe inputs enable time-critical capture of position events during part inspection.
