Q:My Lenovo v450 laptop power adapter should be bad how to match?

In order to ensure quality, we recommend that you buy genuine, you can contact the service station to buy engineers

Q:What is the frequency converter used to do, why some motor with the inverter?

Speed control, there are speed requirements of the place are in the inverter

Q:What is the number of parameters of the motor frequency of the Siemens inverter?

Different types of Siemens frequency changer pole pair parameters different. 6SE70 is p109; The following is the p109 parameter description: P109 * Motor #PolePairs 109 For the synchronous / asynchronous motor input motor pole pairs of the function parameters. If the rated frequency (P107) and rated speed (P108) change, automatic calculation This parameter, if necessary, checks and verifies this parameter. note: - for some of the pulsed encoders (P130 = 11, 12, 15, 16) The maximum number of pole pairs of P109 = 15 can be achieved - P109 must be written when the write function (P060 = 6) is implemented. - Automatic calculation of the pole pair on the motor with regenerative feedback on the rated data Number to be added. Where the function map: 360.2, 361.2, 362.2, 363.2, 364.2 ? MM4 series is r313, which is calculated by the input rated frequency and rated speed calculated read-only value, must be selected in the p3900 to calculate the correct value. You can also set pole pairs by p314. ? S120; G110; G120; G130; G150; S150 with MM4 series.

Q:Siemens g120 inverter torque limit what is the meaning

For example, you have 100kg of power, but you can send the power and you lift the weight of the object, if the object weight of 10kg, you can only use 10kg of power.

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:Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?

Is the inverter must be. Do not know you are also a generic vector. If it is common to directly on the instructions on the motor logarithmic change 6 pole, turn the number changed to 980 on the line. Vector, then change the number of 980 and then learn from the line on the line.

Q:Who knows how the frequency converter works

Rectifier circuit The function of the rectifier circuit is to convert the AC power into a DC power supply. Rectifier circuit is generally a separate rectifier module.

Q:Fuji inverter motor set the number of poles will not have any effect?

The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.
