With automatic restart enabled, what is the number of restarts Altivar 58?

For drives with V5.3 or greater firmware, when the Auto restart is active, the fault relay remains energized. If the fault has disappeared, the drive controller will attempt to restart the motor after a delay time set by parameter tAr. If the drive controller remains faulted after attempting the number of restarts set in the parameter nAr, the fault relay de-energizes and the drive controller must be reset by cycling power. The adjustable range for the number of restarts (nAr) is 0 to 255.

For Altivar 58 drives prior to V5.3, When the Auto restart is active, the fault relay remains energized. If the fault has disappeared, the drive controller will attempt to restart the motor after a delay of 30 s. If the drive controller remains faulted after 6 attempts, the fault relay de-energizes and the drive controller must be reset by cycling power.
