My QT10ATC got alarm on the Freqrol FR-SE 2 times in 2 days.
Both times was in the morning (cold machine) and alarm leds indicates "OVERVOLTAGE (CONVERTER)"
Here is a description of the alarm:
Anyone have any idea.
My gut fealing says its the big capacitors that is unable to accumulate the power generated by the converter during spindle break and the voltage is rising.
When machine is warmer the capacitors work better
Edit: LED17 is not lit when alarmed.
