Q:My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.
For your situation about the summary of recommendations:
First, check whether the motor overload and whether the leakage exceeded,
Second, check and clean the inverter fan, if the room temperature is high, add the external fan to the inverter cooling
Third, if none of the above, then please check the inverter module is burned, replace the module
Fourth, if the inverter is no problem, then the motor and load the problem, if the motor problems are not resolved, then only re-select the inverter, please select the time to increase the margin

O audio adapter
Q:How to learn the inverter debugging and design parameters
Personally think it is relatively simple, and now the inverter has been more intelligent, and some simple applications, and even do not need to set the parameters.
(0 ~ 20mA), but the main input / output is completely isolated, than the output of the inverter simulation of the output of the analog output The amount of signal impact resistance, anti-interference ability.
Q:Laptop adapter heat
Many friends to buy a laptop or laptop power, you may encounter the power did not take long to heat on the hot, and even hot to dare not get the situation, in the end is the quality of power problems or how is it?
With the ever-changing notebook frequency, notebook power adapter power is also sesame flowering high, even to 100W or so, almost a small desktop power! Touch the hand, timid may be scared, obediently, is simply a hot potato! What will not fire? This is a lot of people worry! Compaq, IBM, such a large company to recover several back to the power adapter, it is because of fear that there may be defects due to power supply design, and will cause a fire!
Q:What are the AC motor speed control methods? What are the characteristics of each
Pressure control speed, limited speed range is limited use of variable pole speed, change the motor internal wiring speed, speed is a very speed according to the motor factory set to brand speed to speed control, change the motor input Frequency to speed, are stepless speed is now more popular
Q:Notebook power adapter on how to look at power
It should be noted that there are many in Japan to buy a notebook or over there in the parallel imports, input only support 110V in China is not used, because the Chinese standard is 220V. Now the subject is 90W 20V. Output voltage and power will be identified, such as the target for the 90W 20V, that output power is 90W, the output voltage is 20V. If only the output voltage and output current are identified,
Q:Why G120 inverter to be equipped with 4-pole motor?
I add point with the premise of the inverter is to understand the mechanical load characteristics (or process, etc.), can the parameters set.
Q:Is the laptop power adapter high temperature normal? Is there anything else?
Hello, the power adapter because there are a lot of electronic components so hot is normal, the general hand feels hot does not feel hot on it, if hot, then there is a problem.
Q:Laptop power adapter (no power supply, but indicator light)
There may be reasons for the power adapter, there may be a computer can not identify the power supply is battery-powered or AC power. These are just speculated by your phenomenon, if you are better in the warranty period to the customer service test, so the best
