Powtran PI8600 F Series User Manual page 135

Inappropriate parameter is set
Power voltage exceeds the
limit
Over
voltage
Too fast deceleration
E.OU
The load has too much inertia
Too low power voltage
Low
voltage
Power off transiently
E.LU
The line has too small capacity
or great rush current exists on
the lines.
Too high ambient temperature
Over heat
Cooling fans do not work
E.OHt
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.
Section VI Fault Diagnosis & Solutions
Modify b04、b14 in case of the motor overload
allowed
Check voltage is right or not.
Frequency inverter rated voltage setting is Y
or N.
Modify F10.
Reduce the load inertia, or raise the capacity
of frequency converter, or add a braking
resistor.
Checking voltage is normal or not.
Frequency inverter rated voltage setting is Y
or N.
Add options of capacitor boxes
Make renovation on power supply system.
Improve ambient conditions
Check A27, reduce fan starting tamperaturer
(when there is fan control)
