SRVO-081: EROFL alarm (track encoder overflow)
Line-tracking alarm: the pulse count from the conveyor-tracking encoder overflowed - the tracking system counted faster or longer than it can handle, usually a conveyor running beyond the tracking limits.
What it means
Line-tracking alarm: the pulse count from the conveyor-tracking encoder overflowed - the tracking system counted faster or longer than it can handle, usually a conveyor running beyond the tracking limits.
Common causes
Ranked by what technicians most often find, most likely first.
- Conveyor/encoder speed exceeding the line-tracking limitation.
- Faulty incremental encoder, tracking cable, or line tracking interface board.
How to fix it
- Check the tracking application against its limits; reduce conveyor speed if it's over.
- Then hardware in order: tracking encoder, tracking cable, line tracking I/F board. Power-cycle to clear.
