Ensurean automatic restart does not present a danger forpersonnel.With the default settings, each fault triggers a fault message. Anautomatic restart is possible after the following fault messageshave occurred:• Overcurrent (up to three restarting attempts, then fault signalE 01 to E 04)• Overvoltage (up to three restarting attempts, then fault signalE 07 and E 15)• Undervoltage, intermittent supply voltage failure (up to 16restart attempts, then fault signal E 09)When the maximum number of permissible automatic restarts (3or 16) is reached, the frequency inverter must be restarted.With PNU b002 and b003, specify the behaviour on mains failure(a fig. 166 and fig. 167). Under PNU b004, define how the DF51 frequency inverterresponds to an intermittent power supply failure or undervoltage.With PNU b005, define whether the DF51 frequency inverterU LNattempts a restart up to 16 times or indefinitely in the event of anintermittent power supply failure or undervoltage.U 2n Mt OaU LNU 2n Mt OaPNU b002Figure 167: Supply voltage downtime greater than value inPNU b002U LN : Supply voltageU 2 : Output voltagen M : Motor speedt 0 : Duration of supply failurea Free run stop (coasting)If mains power returns after expiry of the time set with PNU b002and a start signal is applied, a restart is performed.PNU b002PNU b003Figure 166: Supply voltage downtime less than value in PNU b002,automatic restart184
