Section VII. Fault Diagnosis and Solutions
Disturbance
Check the earthing wire, screened cable
grounding and terminals.
Too much load
Lower the load.or enlarge b01 in the allowable
load range or enlarge F46 to raise the protection
level.
overload
OL
Inappropriate param
set
Modify the parameters of the functions b01.
Power voltage exceeds
the limit
Checking voltage is right or not.
Frequency inverter rated voltage setting is right
or not.
Too fast deceleration Modify the parameters of the functions F10.
Over voltage
OU
The load has too much
inertia
Reduce the load inertia, or raise the capacity of
frequency converter, or use B type converter or
add a braking unit.
Too low power voltage
Checking voltage is right or not.
Frequency inverter rated voltage setting is right
or not.
The power is off
transiently
Add options of capacitor boxes.
Low voltage
LU
The line has too small
capacity or great rush
current exists on the lines.
Make renovation on power supply system.
Too high ambient
temperature
Improve ambient conditions.
Overheat
OH
The carrier frequency is
too high
Check the setting value of function F15.
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.
