￭ 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.
