Q:The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?
Excessive voltage generation and regenerative braking, the so-called inverter over-voltage, refers to a variety of reasons caused by inverter voltage exceeds the rated voltage, concentrated in the DC bus frequency converter DC voltage. In normal operation, the DC part voltage of converter is the average value after three-phase full wave rectification.
Q:Knowledge, principle and operation method of frequency converter.
Sinusoidal pulse width modulation (SPWM) of U/f=C with frequency converter control mode:The characteristics of SPWM inverter control way is to control the circuit has simple structure and low cost, the mechanical properties of hardness is also good, can meet the general requirements of smooth speed transmission, has been widely used in various fields of industry. However, when the output voltage is low, the torque is significantly affected by the stator resistance pressure drop, so that the maximum output torque is reduced. In addition, the mechanical characteristics of DC motor can not hard, dynamic torque capacity and static performance is not satisfactory, and the system performance is not high, the control curve will change with the change of the load torque and motor torque, slow response, low utilization rate is not high, due to the stator resistance and the existence of dead time effect of the inverter performance the poor stability, etc.. Therefore, people have studied vector control frequency conversion speed regulation.
Q:Heating inverter commissioning steps
And carry on the test run 1. manual operation of the frequency converter panel running stop, observe the motor running process and the frequency converter display window, to see if there is abnormal phenomenon. 2. if the P is started and the over-current protection is stopped in the motor, the acceleration P deceleration time should be reset. The acceleration of the motor during acceleration and deceleration depends on the acceleration torque, while the frequency change rate of the inverter during the start and braking is set by the user. If the inertia of motor or motor load change, speed or deceleration rate according to frequency change preset when possible acceleration torque is not enough, resulting in motor stall, motor speed and the inverter output frequency coordination, thus causing overcurrent or overvoltage. Therefore, it is necessary to set acceleration and deceleration time according to the inertia and load of the motor, so that the frequency change rate of the converter can be coordinated with the speed change rate of the motor.
Q:Can the motor with frequency converter directly wave the insulation?
The use of motor inverter drive, if the measurement will not disconnect the motor and inverter, tramegger issued a "high voltage" will spread through the winding inverter inside, will lead to some components breakdown within the inverter a damaged, because some components although the internal current is higher but the degree of pressure will be very limitedTherefore, in shaking the test of the use of inverter motor insulation, the inverter and motor connection is broken after the start, you can ensure that the frequency converter will not be damaged.
Q:How can I learn the converter well?
Frequency converter this thing, in fact, still very practical, so can go to customers to install and debug, is a shortcut to quickly learn the frequency converter. In the installation of debugging, you can take time to read several times the frequency converter manual, and if you can discuss with technical support, I believe you will soon enter the role.
Q:How does the PLC process the inverter output signal?
Frequency converter frequency signal will actually be converted to 4-20mA signal output, access to the PLC AI channel, SIEMENS 200 PLC, some CPU module comes with AI input, but also has a dedicated AI expansion module. What's left is software programming
Q:Frequency converter size selection
Should be able to, in the design of the inverter in consideration of the corresponding motor power matching. Choose a large capacity, a little waste Oh! Our company choose frequency converter is one-to-one correspondence, did not choose the large capacity.
Q:What do you mean by the capacity of the inverter and the capacity of the motor?
That's not the case at all"Capacity" and "power" are essentially different. Usually we say that a large transformer capacity is how much KVA, but not to say how much KW, because the two are not the same thing
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:Frequency converter OC alarm, what's the matter?
And some did not inform you of the inverter fault category, when the OC boot failure, will cause greater danger, then simply caused by surface phenomenon similar to program crashes, such as the P9/G9 series machine when the machine detects INVT, module failure, operationThe H00 character appears on the panel, and all key actions are rejected. Unknown insider will think: program crash, CPU motherboard is a problem.
