<1> When L2-01 is set to 1 through 4 (continue operation during momentary power loss)
Use parameters L5-01 to L5-05 to set up automatic fault restart.
Set H2-01, H2-02, or H2-03 to 1E. to output a signal during fault restart.
n L5-01: Number of Auto Restart Attempts
Sets the number of times that the drive may attempt to restart itself.
Parameter L5-05 determines the method of incrementing the restart counter. When the counter reaches the number set to L5-01,
the operation stops and the fault must be manually cleared and reset.
The restart counter is incremented at each restart attempt, regardless of whether the attempt was successful. When the counter
reaches the number set to L5-01, the operation stops and the fault must be manually cleared and reset.
The number of fault restarts is reset to zero when:
• The drive operates normally for 10 minutes following a fault restart.
• A fault is cleared manually after protective functions are triggered.
• The power supply is cycled.
No.
L5-01
n L5-02: Auto Restart Fault Output Operation Selection
Determines if a fault output is triggered (H2-oo = E) when the drive attempts to restart.
No.
L5-02
Setting 0: No fault output
Setting 1: Fault output is set
n L5-04: Fault Reset Interval Time
Determines the amount of time to wait between restart attempts when parameter L5-05 is set to 1.
No.
L5-04
n L5-05: Fault Reset Operation Selection
No.
L5-05
Setting 0: Count successful restarts
The drive will continuously attempt to restart. If it restarts successfully, the restart counter is increased. This operation is
repeated each time a fault occurs until the counter reaches the value set to L5-01.
Setting 1: Count restart attempts
The drive will attempt to restart using the time interval set to parameter L5-04. A record is kept of the number of attempts to
restart to the drive, regardless of whether those attempts were successful. When the number of attempted restarts exceeds the
value set to L5-01, the drive stops attempting to restart.
