Chapter 12 Inverter Function
12.19.15 Outputting a warning when the
incoming voltage is high
• I want to generate a warning when the power
supply voltage is high.
• Assign the output terminal function 081 [OVS]
incoming overvoltage signal to one of [CC-01] to
[CC-17] that corresponds to the output terminal
and output the signal.
• The incoming overvoltage signal [OVS] turns on
when the PN voltage of the main circuit exceeds
the voltage level specified with the incoming
overvoltage level selection [bb-62] for 100 s
continuously.
• When incoming overvoltage level [bb-61] is set to
00, the signal [OVS] will be output.
• When incoming overvoltage level [bb-61] is set to
01, the signal [OVS] will be output, while a trip
being made due to incoming overvoltage error
[E015].
Parameter
• This function performs detection only when the
inverter is stopped. This function does not work
while the inverter is in operation.
