0V Stop Function; Resetting Fault Trips - Panasonic VF0 Series 400V class 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
"1", and the bias frequency (parameter P56) is set to "0.1" or more.

Resetting Fault Trips

Turn OFF the power once, then turn it ON again.
(Operation can be started when the power is turned ON again.)
(1) When operation is set to local (Parameter P09 set to "0" or "1")
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.
(1) When operation is set to external (Parameter P09 set to "4" or "5")
The fault will not be reset even if the "run command switch" is turned
OFF from an external source.
The fault will be reset when the "STOP button" on the operation panel is
pressed. Operation can be restarted after this.
(1) When setting data is set to "1" for parameters P19, P20 and P21
The fault will be reset when the switch set for the function is turned "ON"
and "OFF". Operation can be restarted after this. (Refer to page 68.)
