SINAMICS V20 F2 — Overvoltage
Trip — immediate stop
CAUSE
Why does it occur?
Excessive regenerative voltage during deceleration, or input supply overvoltage.
REMEDY · Step by step
How to fix it?
Increase deceleration time, add a braking resistor, and measure the input supply voltage.
Do not reset repeatedly before identifying the cause. Repeated resets while ignoring a trip/alarm can cause secondary damage (IGBT failure, motor winding damage, etc.).
