￭ Automatic fault resets
WARNING!
Before you activate the function, make sure that no dangerous situations can
occur. The function resets the drive automatically and continues operation after
a fault.
The drive can automatically reset itself after overcurrent, overvoltage, undervoltage and
external faults. The user can also specify a fault (excluding Safe torque off related faults)
to be reset automatically.
By default, automatic resets are off and must be specifically activated by the user.
