status
When P92.00=1, if the bus voltage is less than
(P92.01*Motor rated voltage), low voltage
protection is started, the VFD decelerates to
stop.
If the bus voltage restores to a value greater
than (P92.01*Motor rated voltage + 20V), low
voltage protection is automatically disabled.
P92.00 setting range:
0: Disable
1: Enable
P92.01 setting range: 1.00–1.30
Low-speed run protection is applied to devices
to which long-time low speed running is not
applicable, preventing overheating caused by
late dissipation.
