Allen-Bradley · PowerFlex 700
What does 92 mean?
The Z Channel is selected as a pulse input, and no signal is present. This indicates a loss of feedback from a pulse generator connected to the Z Channel input, critical for applications requiring pulse-based speed or position control.
Common Causes
- Interruption of the pulse train signal from a sensor or encoder.
- Encoder connection failure or damage.
- Mechanical issue causing erratic pulse generation.
- Faulty encoder or pulse input circuitry.
