Note
•
To prevent a repeat fault trip from occurring when a load, such as a fan, is free-running on a
Power-on Run, set CON-71 (speed search options) bit 4 to
“1”. The inverter will perform a speed
search at the beginning of the operation. If the speed search is not enabled, the inverter will
start its operation in a normal V/F pattern and accelerate the motor.
•
If the inverter has been turned on without Power-on Run enabled, the terminal block command
must be first turned off, and then turned o
n again to begin the inverter’s operation.
7.9
Reset and Restart
The reset and restart operations can be set up for inverter operation following a fault trip,
based on the terminal block operation command (if it is configured).
•
Use caution when operating the inverter with reset and restart enabled as the motor will begin
rotating when the inverter starts up.
•
Stop the frequency reference signal if you do not want the inverter to run again after a
reset.
Set PRT-08 (RST Restart) to
“
1 (yes)
”
to allow the inverter to start operating after it is reset if a
fault trip occurs. PRT-10 (
Retry Delay)
sets the delay time for a restart (the time the inverter will
wait before it restarts).
The number of auto-restarts (PRT-09) refers to the number of times the inverter will try
restarting its operation. If fault trips occur again after a restart, the retry number counts down
each time the inverter restarts until the number becomes “0”. Once the inverter re
starts
successfully after the initial fault trip, the inverter does not restart until the next fault trip occurs.
The number of auto-restarts set at PRT-09 that decreased after a restart reverts to the original
setting value if successful operation continues for a certain period of time.
