SRVO-277: Panel E-stop (SVEMG abnormal)
SVEMG-family fault for the operator panel button: it was pressed but the emergency stop line didn't disconnect.
What it means
SVEMG-family fault for the operator panel button: it was pressed but the emergency stop line didn't disconnect. One redeeming quirk the manual documents: pressing the button too SLOWLY can trigger this falsely - so the retest matters before condemning hardware.
Common causes
Ranked by what technicians most often find, most likely first.
- Button pressed too slowly - a documented false trigger; retest with a firm, quick press.
- Genuine fault in the E-stop line's related parts.
How to fix it
- Release the panel E-stop and cycle controller power.
- Press the button again, firmly and at normal speed: if the alarm does NOT recur, it was the slow-press quirk - done.
- If it recurs, the stop function is genuinely suspect: maintenance-manual diagnosis, qualified personnel, no production meanwhile. Power-cycle to clear.
