: Automatic restart, after locking on a fault, if the fault has disappeared and the other
operating conditions permit the restart. The restart is performed by a series of automatic attempts
separated by increasingly longer waiting periods: 1 s, 5 s, 10 s, then 1 mn for the following attempts.
The drive fault relay remains activated if this function is active. The speed reference and the operating
direction must be maintained.
Use 2-wire control (

If the restart has not taken place once the configurable time tAr has elapsed, the procedure is aborted and
the drive remains locked until it is turned off and then on again.
