Motion and state
Its rotary state can be driven from a PLC output so speed and direction remain visible during a scan.
PLC control pattern
Commission it by proving encoder count before accepting forward, reverse, speed reference.
Fault practice
Inject jammed, slow states and require the PLC sequence to detect, stop and recover deliberately.
Signal map
I/O you can reason about
PLC output Forward; PLC output Reverse; PLC output Speed reference (m/s); PLC input Encoder count
| Signal | PLC direction | Type / range |
|---|---|---|
| Forward forward | output | bool |
| Reverse reverse | output | bool |
| Speed reference speed | output | float · m/s · -0.8–0.8 |
| Encoder count encoder | input | int |
Fault and recovery exercise
Make abnormal states part of the sequence
Inject jammed, slow states and require the PLC sequence to detect, stop and recover deliberately.

Engineering boundary
The model teaches PLC sequence behaviour and diagnosis. Confirm ratings, wiring, guarding, process calculations and commissioning limits against the real manufacturer documentation and site design.
