V/f CL-V/f OLV CLV
Sets the number of times that the drive will try to restart.
V/f CL-V/f OLV CLV
Sets the function that sends signals to the MFDO terminal set for Fault [H2-xx = E] while the drive
is automatically restarting.
V/f CL-V/f OLV CLV
Sets the time for which the drive will try to restart. If the drive cannot restart inthe time set in L5-03,
the drive detects a fault. This is available when L5-05 = 0 [Auto-Restart Method = Continuous/
Immediate Attempts].
V/f CL-V/f OLV CLV
Sets the time interval between each Auto Restart attempt. This function is enabled when L5-05 = 1
[Auto Restart Operation Selection = Use L5-04 Time].
