state. See parameters f107 and f111.
--u-
Overvoltage early warning
Inverter approaches overvoltage fault.
See parameters f415 and f416.
-i--
Overload early warning
This code is displayed when the motor or
inverter overload counter exceeds 50%.
h---
Overheat early warning
Inverter approaches overheat fault.
Note: Early warning types can occur simultaneously. E.g, when overheat early warning
and overcurrent early warning happen in the same time, the corresponding code is h--c.
Restart of the inverter after fault occurs
After failure occurs in the inverter, it can be restarted only when the cause of the failure
has been eliminated. Please follow the undermentioned operations to realize fault reset
of the inverter.
1 When the command source of the inverter is keyboard panel (under local control
mode, or under remote mode and f002 = 1), press STOP key on the keyboard panel
after the fault is eliminated. The keyboard will display a-00. Press the STOP key again,
and the inverter realizes fault reset. At this moment it is allowable toto re-supply power to
the motor.
2 When the inverter is under remote control mode and f002 = 0, set the input function
configuration of any logic input terminal to 10. Then the inverter can use this terminal to
perform fault reset.
3 When the inverter is under remote control mode and f002 = 2, fault reset is realized
through remote communication devices. See
Appendix A: Serial communication
.
4 Switch off the inverter and power it on again.
Note: When the fault is motor or frequency overload (e-21 or e-22), inverter reset
function can not be performed if computed cooling time is not up. The computed cooling
time is specified as: e-21, 30 seconds after the fault occurs; e-22, 120 seconds after the
fault occurs.
