Q: The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?: Can be used, their rated current is not the same, the need to use the inverter over-current overload protection and other parameters for the corresponding changes.

Q: 380V motor addition to the inverter, but also how to change its speed?: 1. Change the number of pole pairs of the motor. (Multi-pole motor use) 2. Use the frequency converter to change the frequency

Q: How does the laptop's power adapter open: Notebook power adapter using the correct method] 1. Try to avoid the use of outdoor or harsh environments to prevent the adapter is exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter.

Q: Is the speed of the motor controlled?: Change the external conditions, you can change the motor speed: 1. Change the number of pole pairs of the motor. (Multi-pole motor use) 2. Use the frequency converter to change the frequency speed 3. Winding motor rotor series resistance speed control. 4. Slip motor is to change the slip electromagnetic speed

Q: Laptop power adapter aging: This is not much relationship with the adapter, is your laptop internal hardware overheating, leading to self-protection open and shut down.

Q: What is the single axis of the inverter and multi-axis applications: The frequency changer mainly consists of rectification (alternating current direct current), filter, re-rectification (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on.

Q: There is no inverter comes with simple PLC programming function: The inverter is an AC speed control device, like DC speed control device, DC speed is to change the armature and excitation current, and it is the input AC through the internal circuit into DC, DC and then DC, the last DC AC output, this is the original 50Hz frequency AC can output other frequencies of alternating current, because the speed v is proportional to the frequency f, so you can set the frequency of the inverter to change the speed of the control motor. It does not have its own programming function. But there are servo drives, in fact, is a frequency converter, but can handle some of their own signals, usually from the servo motor on the encoder, and then control the servo motor to achieve precise control.

Q: What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor: 2, the ordinary asynchronous motor is the cooling fan and motor spindle connection, the motor speed determines the cooling fan speed, low frequency when the motor rotation is slow, so the motor temperature rise is the principle.

Q: 400w 6-pole motor should be equipped with much of the inverter?: Under normal circumstances, the market are sold on the inverter are based on the common 4-pole motor matching, when to match the 6-pole motor, the inverter to a large power level, which is 400W of the first-class power 0.75KW, and so on

Q: Siemens g120 inverter torque limit what is the meaning: Torque is a strain, the inverter can not actively control the output torque size, only according to the size of the load demand torque, the output of the corresponding torque.
