Range: 0.5-10.0s 【 This value depends on the
inverter model】
P1.16 Trip-free time
Note:
◆If having the speed track optional parts, P1.15 could set to 1 or 2.
◆If under voltage occurred in trip-time, the inverter will display Uu alarm only, and the
motor cannot startup at this time. As shown in Fig. 5-1-7:
◆If under voltage occurred in running, the inverter will display “Uu” alarm and “Uu1”
fault, as shown in Fig.5-1-7. And PWM output inhibited, motor runs at zero-speed. If
the voltage recovered, “Uu” alarm will disappear,
If Uu1 fault occurred, the inverter will stop .If the voltage continues to drop to below
300V, a failure history record or a fault output will not happen. However, if the voltage
restored, the system will record the Uu1 fault.
