L5: Fault Restart
The drive can be set up to perform a self-diagnostic check and resume the operation after a fault has occurred. If the self-
check is successful and the cause of the fault has disappeared, the drive restarts by performing Speed Search (
Refer to
b3: Speed Search on page 110
for details).
The drive can attempt to restart itself following the faults listed below.

Use parameters L5-01 to L5-05 to set up automatic fault restart.
To output a signal during fault restart, set H2-01, H2-02, or H2-03 to 1E.
Do not use the fault restart function in hoist applications.

L5-01: Number of Auto Restart Attempts
Sets the number of times that the drive may attempt to restart itself.

The method of incrementing the restart counter is determined by the setting of parameter L5-05. When the counter reaches
the number set in L5-01 the operation stops and the fault has to be reset manually after correcting the cause.
The restart counter is incremented at each restart attempt, regardless of whether the attempt was successful. When the
counter reaches the number set in L5-01 the operation stops and the fault has to be reset manually after correcting the
cause.
The number of fault restarts is reset back to zero when:
• The drive operates normally for ten minutes following a fault restart.
• A fault is cleared manually after protective functions are triggered.
• The power supply is cycled.
n
L5-02: Auto Restart Fault Output Operation Selection
Selects if the fault output (H2-01/02/03 = E) is set when the drive attempts to restart.

is repeated each time a fault occurs until the counter reaches the value set in L5-01.
