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 at speed, fault before accepting run command, speed reference.
Fault practice
Inject stuck-on, stuck-off states and require the PLC sequence to detect, stop and recover deliberately.
Signal map
I/O you can reason about
PLC output Run command; PLC output Speed reference (Hz); PLC input At speed; PLC input Fault
| Signal | PLC direction | Type / range |
|---|---|---|
| Run command run | output | bool |
| Speed reference speed | output | float · Hz · 0–60 |
| At speed at_speed | input | bool |
| Fault fault | input | bool |
Fault and recovery exercise
Make abnormal states part of the sequence
Inject stuck-on, stuck-off 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.
