SRVO-278: TP E-stop (SVEMG abnormal)
Same SVEMG fault as SRVO-277, for the teach pendant's E-stop button - pressed, but the line didn't drop.
What it means
Same SVEMG fault as SRVO-277, for the teach pendant's E-stop button - pressed, but the line didn't drop. Same slow-press quirk applies.
Common causes
Ranked by what technicians most often find, most likely first.
- Button pressed too slowly (documented false trigger).
- Genuine E-stop line fault.
How to fix it
- Release the TP E-stop, cycle power, retest with a firm press.
- Recurrence = failed safety function: diagnose per the maintenance manual before running production. Power-cycle to clear.
