The spare parts shall be stored in dry ambient, which is far away from the corrosive gas. All printed circuit board should be stored in electrostatics proof package. Please handle the packaged spared parts carefully for the convenient of troubleshooting and maintenance after send back to factory.

 Replacing Spare Parts from the original package, prevent carefully from electrostatics discharging. The impropriety operation may cause sensitive parts damage, and the following procedures should be followed .Even short-distance transportation, spare part should also be shipped in electrostatics proof package

When handling the PCB, always hold it by its edge to prevent terminals and component damage. The PCB audits component should place on a grounded operation table to prevent electrostatics effect .The failed PCB should also be shipped or delivered in electrostatics proof package to prevent the electrostatic damage.

Q:My motor is a low frequency 8 pole motor, about 80W. I would like to choose a frequency converter
Poor match, the program is unreasonable Current 1.5A, choose a single-phase 220v power supply, 370-500w inverter it
Q:Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total
Is it right? The next manual to see do not understand
Q:Can the inverter be used to control the speed of the DC motor?
The inverter can be used to control the speed of the DC motor. Inverter control DC motor is to control the DC motor. Inverter is the application of frequency conversion technology and microelectronics technology to change the AC power frequency and effective voltage power control equipment. The frequency converter is usually used to control the AC motor. Inverter at work can change the AC power frequency and effective voltage, another point of view, is the inverter in the control output (injected into the controlled device) AC frequency, but also control the output of the effective power. A DC motor is a rotating electric machine that converts DC power into mechanical energy. DC motor coil in the current must be in accordance with certain changes (commutation) can be rotated, according to the principle of commutation DC motor can be divided into brush and brushless motor two categories.
Q:Delta VFD-F frequency converter how to adjust the number of poles
P148 look, this is to correspond to the number of poles of the motor, not to adjust the number of poles of the motor
Q:ASUS power adapter Acer can use it
3. The size of the joint is appropriate. (If the connector is too loose, will be bad, excessive fever.) If it is for DELL and HP / Compaq and other notebook power adapter, will involve a decoding problem. Please pay attention when the pro to buy. Acer and Asus are not yet available. It is said that the market is also very popular universal adapter, a friend bought a LVSUN brand universal adapter LS-PAB90-BC10, with eight joints. Adapter has a liquid crystal display, you can also automatically switch the voltage, very smart, with more than a year, has also been used.
Q:Why the number of motor poles increased, the inverter capacity will increase
The power of the three-phase motor is equal to the root number of 3 times the line current and the line voltage of the product again good with the power factor. Can also be 3 times the phase current and phase voltage of the good product and then good to power factor. The frequency converter should match the rated current of the motor, not the power of the motor.
Q:What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
Generally transferred to 60Hz, about 1800 rpm, although the maximum speed when the inverter speed adjustable to 135Hz, but the motor does not work. Bearing first to consider.
Q:HP laptop power adapter how to open
HP notebook power adapter for the full size of the design, you can follow the following steps to dismantle: 1, notebook computer power adapter for the injection molding package or with a strong adhesive glue, without any screws, so generally only with violence to crack. However, as long as the method properly, after the dismantling of the power adapter can be restored to the original, do not carefully observe almost no traces of open. 2, the power adapter on the side of the side of the white paper, with an electric knife edge along the power adapter between the gap between the cover, and then hit the electric knife with a hammer, so that the electric knife from the adapter between the upper and lower cover go with. In the different positions of the gap between the upper and lower covers of the adapter, use the tip of the electric knife to be scratched along the gap. When the upper and lower covers are first split, the depth of the tool is deep and then the upper and lower covers of the adapter are separated. 3, then open the shell of the power adapter, you can see the adapter circuit outside the package with a copper shield, with a knife to cut the shielding tape on the tape, and then use the soldering iron shield and the internal circuit board connected to the two Solder joints, you can remove the shield. 4, between the shield and the circuit board is also separated by a layer of thick plastic film, and then cut off the knife after the United States, you can see the circuit board "Lushan true"
Q:What is the meaning of the bipolar polarity in the inverter ah There is a +10V signal input is a -10V What is the meaning of ah?
Bipolar input is positive and negative. Bipolar input is generally used to directly through the external reference or potentiometer to achieve the motor forward and reverse switching, without having to switch all the way to switch the signal (switch).
Q:How to make the motor speed (control speed), can not use frequency
In general, the torque generated by the motor is reduced with decreasing frequency (decrease in speed), and the reduced actual data is given in some frequency converter manuals. By using the flux vector control of the inverter, will improve the motor at low speed torque, even in the low speed area motor can also output enough torque. When the frequency converter to speed up to 60Hz frequency, the motor output torque will reduce the normal motor is designed to 50Hz (60Hz) voltage, the rated torque is given in this voltage range. So the rated frequency under the speed is called constant torque speed, the inverter output frequency is greater than 50Hz frequency, the motor torque to be inversely proportional to the frequency of the relationship between the decline. When the motor is running at a frequency greater than 60 Hz, the magnitude of the motor load must be taken into account to prevent the motor output torque from being insufficient. For example, when the torque generated by the motor at 100 Hz is about to be reduced to about 50 Hz, the torque is generated. So the rated frequency above the speed is called constant power speed.
