Momentary Power Interruption/Trip Retry (Restart)
This function allows you to determine the operation performed when a trip occurs due to momentary
power interruption, undervoltage, overcurrent, or overvoltage.
Set the retry condition according to your system.
Trip Retry Function
• Select the retry function during operation in [b001] (01 or 02). If [b005] is 00 (default), the following
operations are to be performed.
At the time of momentary power interruption and undervoltage: Restarts 16 times and trips on
the 17th time.
At the time of overcurrent and overvoltage: Restarts 3 times respectively and trips on the 4th
time.
Retry times are counted separately for momentary power interruption, undervoltage, overcurrent,
and overvoltage. For example, an overvoltage trip occurs only after 3-time overcurrent trips and
then 4-time overvoltage trips. For momentary power interruption and undervoltage, if [b005] is set
to 01, the retry operation continues until the status is cleared.
• You can select the operation for momentary power interruption and undervoltage during stop in
b004.
(Supplemental Information)
Frequency matching start: Restarts the motor without stopping it after matching the motor rotation
speed. (If the RUN command is set on the Digital Operator (A002 = 2),
the Inverter stops.)
Parameter No.
