Q:At the base block Yaskawa inverter is what reason?: This is the base block command, when the external input block command signal, the frequency converter will appear this code, the emergence of this code, the motor will rotate freely, does not affect the use.

Q:What is the difference between frequency converter and servo driver?: The difference between servomotor and frequency conversion motor:Servo system is a closed-loop control system, the inverter usually works in open-loop control, so in terms of speed and accuracy, and can not be compared to the servo drive.The frequency conversion is only one part of the servo, and the servo controls the closed loop precisely on the basis of frequency conversion so as to achieve better results.

Q:What does "frequency" in household appliances mean?: The air conditioner in Japan is gradually changed from pure PWM control to PWM ten PAM mixed control mode. The speed is controlled by PWM, U / F to maintain; when the speed exceeds a certain value, the system will adjust the fixed at the maximum value near, by changing the DC chopper on duty LL, improve the inverter input DC voltage, so as to keep the inverter output voltage and speed is proportional to the area, said PAM area

Q:What are the key points of frequency converter maintenance?: Frequency converter daily patrolDo the inverter daily inspection and inspection work, inspection contents mainly include: ambient temperature, humidity is required, ventilation windows is good; the inverter air inlet and outlet is blocked by dust or too much dust; inverter operation parameter is normal, there is no alarm; cabinet fan the operation is normal; if there is abnormal sound or vibration transducer; capacitor whether overheat.

Q:What is the difference between inverter energy consumption braking and motor energy consumption braking?: A direct current is generated in the stator winding so that a fixed magnetic field is generated. At this point, the rotor cuts the magnetic field lines in the direction of rotation, resulting in a braking torque. Because the braking method is not like regenerative braking (using frequency converter), the energy generated by braking is fed back to the grid, but the energy is dissipated by the motor alone, so it is called energy consumption braking. The utility model is also used for braking by direct current in the stator winding, so the energy consumption braking is called DC injection braking. By using the backward switch Q to return the point voltage back to the grid, the armature current will become a copy, and the current will be of the same magnitude, resulting in a great braking torque of the motor, which will stop the motor.

Q:What is the function of a frequency converter on an electric motor?: Mainly for AC motor speed regulation, but also is a smooth stepless speed regulation. You can also implement some specific controls.

Q:What are the differences between the two quadrant and the four quadrant of the inverter?: The four quadrant inverter can not only drag the motor forward and backward, but also convert the kinetic energy of the motor idle time into electrical energy and feed it back to the power grid. Cause the motor to operate in the generator. Often used in some promotional occasions.

Q:What is the difference between a frequency converter and a servo controller?: The speed of an asynchronous motor is =60f/p.f, the frequency of alternating current, P is the pole, and the logarithm.60 is the number of seconds in a minute. As can be seen from the form, the number of poles has been fixed. The speed of the asynchronous motor is proportional to the frequency of the power supply. The frequency of the asynchronous motor is changed by changing the frequency of the power supply. This is the principle of variable frequency speed regulation

Q:Application of ABB frequency converter: What are the differences between PWM and PAM?PWM is English Pulse Width Modulation (pulse width modulation), according to the law must change the pulse of the pulse width in a tone adjustment output and waveform.PAM is the abbreviation of Pulse Amplitude Modulation (pulse amplitude modulation) in English. It is a modulation way to change the pulse amplitude of pulse column according to a certain rule to regulate the output value and waveform.

Q:What are the precautions for frequency converter wiring installation?: The control signal line should not be parallel to the power line. If parallel must be used, the shielding wire and one end of the earth must be used.To use 485 or 232 communication, wear a magnetic ring and use twisted pairs.
