Product Description:

The CSH01.1C-PB-EN1-NNN-MEM-S1-S-NN-FW is a motion controller card manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed as a plug-in module for IndraDrive platforms, it coordinates servo axes, handles PROFIBUS fieldbus traffic, and provides integrated safety inputs for plant machinery. In industrial automation, it serves as the central processor that converts PLC commands or PROFIBUS messages into precise drive-level motion instructions. By combining motion control, network communication, and safety-related signal handling on one module, the card supports compact drive layouts without requiring separate processing hardware for these tasks.

The card’s base power draw is 7.5 W, so cabinet power budgeting can be planned without oversizing supplies. Two analog monitor channels deliver a 1 mA current signal or a 5 V voltage signal for drive status feedback to legacy equipment. During startup, the controller briefly pulls 4 A of inrush current with a 100 ms pulse width, so upstream protection must tolerate that transient. Motion simulation signals can be fed to an external oscilloscope through the emulation port, which sources 20 mA at frequencies up to 1 MHz for high-speed verification of position loops. All cyclic command data reach the module over the PROFIBUS-DP interface, which keeps wiring consistent with existing factory networks and simplifies integration with established control architectures.

The feedback side uses a resolver/HSF encoder interface that supplies 8 V excitation to the transducer, while a carrier of 18.2 Vpp at 4 kHz supports signal transmission across long motor cables. Safety circuitry receives 1.6 A to power dual-channel input blocks, and each input expects a nominal 24 V / 3 mA while the solid-state outputs can switch 24 V / 0.5 A to downstream contactors. This arrangement keeps the feedback path and the safety channel clearly separated while allowing both functions to operate from the same controller card. Resolver feedback, encoder supply capacity, and the stated safety current limits allow the controller to participate in Category 3 stop circuits without exceeding relay ratings.
