Cause:
Influenced by Electrical Magnetic Interference.
Remedy:
Keep such noise source away from the frequency inverter.
Cause:
Ambient temperature is too high.
Remedy:
Take countermeasure against high ambient temperature.
Cause:
Component itself is defect.
Remedy:
Replace ISPM (in case of E 11) or I/O board board (in case of E 12).
(7) External Trip (E 12)
Phenomena:
Trip due to have inputted an external signal to “EXT” input terminal of the
frequency inverter.
Cause:
Faulty external device or equipment gives frequency inverter a trip requirement
when external trip function (EXT) is selected.
Remedy:
Evaluate external device or equipment which is connected to frequency inverter.
Way to Reset:
A
(8) USP error (E 13)
Phenomena:
Unexpected Start Protection. This error can occur when “USP” function is
selected.
Cause:
Frequency inverter trips when it is powered up with RUN command is given.
Remedy:
Disable RUN command when power up the frequency inverter. Or disable USP
function if possible to the system.
Way to Reset:
A or set RUN command off (stop)
(9) Ground fault error (E 14)
Phenomena:
Earth contact in the motor or the motor cable or in the IGBT. Frequency inverter
detects this earth contact only at power up.
To resolve the causes , please power off and disconnect the motor wire at INV (UVW)terminal.
Cause:
Earth contact in the motor or the motor cable.
Remedy:
Check the impedance between output portion(wire and motor) and earth.
Cause:
Detection circuit/IGBT of the inverter is defect. If the motor and the motor cable is
disconnected from the frequency inverter, the ground fault should not be detected
anymore.
Remedy:
Please disconnect the motor and the motor cable.
If E14 comes out at power on,please replace the unit.
Way to Reset:
Don’t reset.
