During the working process, the system will continuously monitor the temperature of the
power inverter part of the generator to ensure that it can prevent further temperature rise and
damage the equipment in time when the temperature is too high. The design has fully taken
into account the temperature generation and heat dissipation, and this protection does not
occur under normal circumstances.
When this prompt occurs, try:
Improve the use environment, increase heat dissipation space or provide external heat
dissipation.
Check if the vents are blocked and the fans are not damaged.
Wait a few minutes for the temperature to drop, and then restart the machine to continue
working.
6.5 Error: IGBT overcurrent protection
This protection indicates that some reasons have caused a very large power consumption of
the whole machine, which has exceeded more than twice the rated power in a short period of
time. Special care should be taken.
When this prompt occurs, try:
Check whether the frequency is correct. Under no-load conditions, set the frequency of
chasing frequency to a relatively high value, such as 20.4k for 20k models, and perform
frequency search.
Check if the mold is damaged. Disassemble the mold or replace it with a mold that is
confirmed to be good and check again.
Whether the load is short-circuited. Check whether there is a short-circuit or insufficient
voltage resistance of the load connecting wires and plugs that cause short-circuit overcurrent
protection.
Other issues that can cause severe over power consumption.
6.6 Error: load overcurrent
The system detects that the load current exceeds the internally set protection current value.
When this prompt occurs, you can try:
Check if the load is too heavy. Reduce load
For overcurrent caused by excessive load, you can appropriately increase the amplitude
and output the same power by increasing the driving voltage to reduce the driving current, but
this will more easily cause a warning of excessive load power consumption and have a greater
impact on the life of the mold Big.
If there is no sound wave output, check the load line for short circuit.
Increase the frequency by 0.1khz, try again
6.7 Error: load overvoltage
The system detects that the load voltage exceeds the internally set protection voltage value.
When this prompt occurs, you can try:
Reduce the amplitude to reduce the drive voltage.
Check if the load is not connected.
Check whether the utility power is serious.
