L5-01: Number of Auto Reset Attempts
Sets the number of times that the drive may attempt to reset itself.
The drive will continuously attempt to reset. If it resets successfully, the reset counter is increased. This operation is
repeated each time a fault occurs.
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 reset is reset to zero when:
• The drive operates normally for ten minutes following a fault reset.
• A fault is cleared manually after protective functions are triggered.
• The power supply is cycled.
