Product Description:

The CSH01.3C-S3-EN2-NNN-CCD-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Within an IndraDrive system, it operates as the central processor that executes motion algorithms, supervises Safe Motion functions, and distributes synchronized commands to multiple power modules. By combining axis control, safety monitoring, and field communication in one slot-mounted module, it helps reduce cabinet complexity in printing presses, packaging machines, and material-handling lines. Its role is to coordinate control tasks across the drive system while maintaining consistent signal handling between connected components.

The controller accepts analog feedback through an input resistance of 160 kΩ, allowing high-impedance sensors to operate without excessive loading. Position or process signals are digitized in steps of 1.23 mV/inc, while command values sent to external hardware are issued in increments of 19.5 mV/inc. Each digital output can source up to 500 mA, which is suitable for driving optically isolated relays or status indicators directly. The housing measures 241 × 49.5 × 103 mm, giving the module a narrow profile for compact control cabinets. The cross-communication role is master, so this section handles timing and ring diagnostics for other CSH nodes. Motor feedback is processed through an EnDat 2.1 / 1 Vpp / TTL encoder interface, and motor probes use relay contacts for functions such as brake release or clutch control.

Configuration and diagnostics are handled through an engineering link that runs at 100Base-TX over an RJ-45 service port. Deterministic drive data is exchanged through SERCOS III on the backplane, which supports synchronized communication between the control section and associated drive hardware. Probe capture jitter is limited to 1 µs, which helps maintain accurate registration in cut-to-length or punching applications. Functional safety performance reaches SIL2 / Cat. 3 PL d, allowing the controller to support STO and SS1 functions within the drive system. Additional interfaces include an RS232 serial port for legacy equipment and a Safe Motion channel that can work with door interlocks or light curtains.
