SRVO-093: SPHAL alarm (track encoder speed excess)
Line-tracking mirror of SRVO-071: the conveyor encoder reported implausibly high speed - either the conveyor really is over the tracking limit, or the feedback channel is lying.
What it means
Line-tracking mirror of SRVO-071: the conveyor encoder reported implausibly high speed - either the conveyor really is over the tracking limit, or the feedback channel is lying.
Common causes
Ranked by what technicians most often find, most likely first.
- Conveyor speed genuinely exceeding tracking limits.
- The SRVO-090 suspect list: connections, shielding, cable, encoder, I/F board.
How to fix it
- Check actual conveyor speed against the tracking limitation; slow it if over.
- Otherwise work the SRVO-090 sequence. Power-cycle to clear.
