Section VI
Inappropriate parameter is set
Modify b04、b14 in case of the motor overload
allowed
Over
voltage
E.OU
Power voltage exceeds the
limit
Check voltage is right or not.
Frequency inverter rated voltage setting is Y
or N.
Too fast deceleration
Modify F10.
The load has too much inertia
Reduce the load inertia, or raise the capacity
of frequency converter, or add a braking
resistor.
Low
voltage
E.LU
Too low power voltage
Checking voltage is normal or not.
Frequency inverter rated voltage setting is Y
or N.
Power off transiently
Add options of capacitor boxes
The line has too small capacity
or great rush current exists on
the lines.
Make renovation on power supply system.
Over heat
E.OHt
Too high ambient temperature
Improve ambient conditions
Cooling fans do not work
Check A27, reduce fan starting tamperaturer
(when there is fan control)
The carrier frequency is too high
Check the setting value of function F16
Note:
※ Switch off the power supply, and do not touch the PCBs and any parts inside in five minutes
after the charging indicator light (！CHARGE) goes off. Ensure the capacitance has been
discharged completely by measuring with the instrument before work inside. Otherwise, there
is a danger of electric shock.
※ Do not touch the PCB or IGBT and other internal parts unless actions have been taken to
prevent the static electricity. If not, the components may be damaged.
