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.

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.
