greater than the overspeed detection value(F8.13), and the duration is greater than the overspeed
detection time(F8.14) the inverter will alarm fault ID Err.43, and troubleshoots according to the
protection action.
Detection value for too large speed
deviation
0.0%~50.0%(maximum frequency)
Detection time for too large speed
deviation
This feature is only available when the inverter runs with speed sensor vector control.
When the inverter detects that the actual motor speed is different from the set frequency, and
the deviation is greater than the detection value for too large speed deviation(F8.15), and the
duration is greater than the detection time for too large speed deviation(F8.16), the inverter will
alarm fault ID Err.42, and troubleshoots according to the protection action.
If the detection time for too large speed deviation is 0.0s, the detection for too large speed
deviation is canceled.
