12.19.6 Outputting a warning when a
momentary interruption occurs
• I want to make a notification with a warning when a
momentary interruption occurs.
• Assign the output terminal function 020 [IP] under
momentary interruption signal to one of [CC-01] to
[CC-07] that corresponds to the output terminal
and output the signal.
• The momentary interruption signal can be output
when a momentary interruption occurs in the
inverter main power.
• An interruption in the main power can be output as
a signal when the control power is supplied via a
separate line.
• Example of a momentary interruption
Parameter
• The momentary interruption signal [IP] is valid
when the main power is input from R-S-T.
• The momentary interruption signal [IP] is output
while the control power of the inverter remains
(including when a 24-V power supply is used).
• To set errors that will be generated when a
momentary interruption occurs, refer to 12.16.6
“
Generating a momentary
interruption/undervoltage trip.
”
• To perform retry restart operation without
generating errors when a momentary interruption
occurs, refer to 12.13.7 “Restarting the inverter
after recovering from a momentary interruption.”
