V/F SVC
Set the response effect of undervoltage
suppression.
V/F SVC
The lower limit voltage allowed by the set bus
voltage. Below this value, the VFD reports an
undervoltage fault.
V/F SVC FVC
Set whether the input and output phase loss
protection functions are enabled.
LED "0" digit: Output phase loss protection.
0: Off
1: On
LED "00" digit: Input phase loss protection.
0: Off
1: On, detected the input missing phase report
warning A.ILF, continue to run
2: Turn on, detect input missing phase report
fault E.ILF, free stop
V/F SVC FVC
Set whether the VFD output and the VFD
cooling fan ground short circuit protection
function are enabled.
LED "0" digit: Output short circuit protection.
0: Off 1: On
LED "00" digit: Fan to ground short circuit
protection.
0: Off
1: On
Set the VFD cooling fan operation mode.
0: The fan runs after the VFD is powered on.
1: After the shutdown, the fan operation is
related to temperature, and the operation is
running.
2: After the shutdown, the fan stops after
F10.24, and the operation is related to
temperature.
