When thetime has elapsed, the Inverter tries to automatically restart modulation.P2.7.7.2 Automatic reset Trial TimeID 718If the fault trigger appears more often than defined by parameters P2.7.7.3 to P2.7.7.6inside the trial timeP2.7.7.3 Over voltage Autoreset triesID 721This parameter determines how many automatic restarts can be made during the trialtime set by parameter P2.7.7.2. "Trial Time" After an over voltage trip.0 = No automatic restart after overvoltage fault trip.>0 = Number of automatic restarts after overvoltage fault trip. The fault is reset and theinverter is started automatically after the DC-link voltage has returned to the normallevel.P2.7.7.4 Over current Autoreset triesID 722NOTE! IGBT temp fault also included. This parameter determines how many automaticsrestarts can be made during the trial time set by P2.7.7.2. "Trial Time"0 = No automatic restart after over current fault trip>0 = Number of automatic restarts after over current trip and IGBT temperature faults.P2.7.7.5 External Trip Autoreset triesID 725This parameter determines how many automatics restarts can be made during the trialtime set by P2.7.7.2. "Trial Time"0 = No automatic restart after External fault trip>0 = Number of automatic restarts after External trip.P2.7.7.6 Input Phase Autoreset TriesID 726This parameter determines how many automatics restarts can be made during the timeset by P2.7.7.2.
