Use this parameter to set the maximum time for an underload state. It is the maximum time for the underload state to be active
before an underload fault occurs.
It is possible to set the time limit between 2.0 s and 600.0 s.
An internal counter counts the underload time. If the value of the counter goes above this limit, the protection causes the drive to
trip. The drive trips as is set in parameter ID 713. If the drive stops, the underload counter goes back to 0. See
