Chapter 6 - Parameter Description [FU2]
6-20
This function is used to allow the inverter to reset itself for
a selected number of times after a fault has occurred. The
inverter can restart itself automatically when a fault occurs.
To use the speed search function during auto restarting set
FU2-22 to ‘xx1x’. See FU2-22 ~ FU2-25.
When an under voltage (LV) fault, inverter disable (BX) or
Arm short occurs, the drive does not restart automatically.
☞
Note: Inverter decreases the retry number by one as a fault
occurs. When restarted without a fault during 30 seconds,
the inverter increases the retry number by one.
FU2-28: Speed search hold time
The inverter starts speed search function after the preset
time t1 elapses. Set the desired time for inverter to restart
the previous operation using Speed search function.
Speed search function [FU2-22] is activated automatically
during exchanging function.
