SRVO-085: RCAL alarm (track encoder rotation counter)
Line-tracking mirror of SRVO-063: the conveyor encoder's rotation counter miscounted - grounding/noise first, encoder second.
What it means
Line-tracking mirror of SRVO-063: the conveyor encoder's rotation counter miscounted - grounding/noise first, encoder second.
Common causes
Ranked by what technicians most often find, most likely first.
- Weak grounding at the encoder flange letting noise corrupt the count.
- Phantom alongside SRVO-090/091/092.
- Failed encoder.
How to fix it
- Check the 090/091/092 trio first.
- Reinforce the encoder flange ground.
- Replace the motor/encoder if it persists; recovery is PULSE RESET then power cycle.
