0V Stop Function; Resetting Fault Trips - Panasonic VF0 Series Instruction Manual

If the frequency setting signal is a command (panel potentiometer, external
potentiometer, 0 to 5V, 0 to 10V, 4 to 20mA) other than the "digital setting
with operation panel (parameter P09 = 1)", the inverter will start and stop at
a boundary of approx. 1/100 of the input signal's full scale using the factory
set data.
∗ 0V stop will not take place if the bias/gain function selection (parameter P55) is set to
If a fault is displayed on the operation panel's display and the inverter is
stopped, remedy the fault before resetting.

stop signal The fault will be reset when the "STOP button" on the operation panel is
pressed. Operation can be restarted after this.
(2) When operation is set to external (Parameter P09 set to "2" or "3")
The fault will be reset when the "run command switch" is turned OFF
from the external source. Operation can be restarted after this.
Resetting by (1) When operation is set to external (Parameter P09 set to "4" or "5")
