SRVO-090: DTERR alarm (track encoder no response)
Line-tracking mirror of SRVO-068: the conveyor encoder didn't answer the interface board's data request - a feedback communication failure on the tracking channel.
What it means
Line-tracking mirror of SRVO-068: the conveyor encoder didn't answer the interface board's data request - a feedback communication failure on the tracking channel.
Common causes
Ranked by what technicians most often find, most likely first.
- Cable connections loose at the I/F board or encoder end.
- Shield not grounded at the grounding plate.
- Failed encoder, tracking cable, or line tracking I/F board.
How to fix it
- Reseat both cable ends.
- Verify shield grounding.
- Then replace in order: encoder, tracking cable, I/F board. Power-cycle to clear.
