Q:What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?
Ambient temperature. When the temperature of converter is too high and the temperature changes greatly, the inner of converter is prone to dew. The insulation performance will be greatly reduced, and even short-circuit accident may occur. If necessary, a desiccant and heater must be added to the case.(3) corrosive gases. The use of the environment, if the corrosive gas concentration is large, not only will corrode the components of the lead, printed circuit boards, etc., but also accelerate the aging of plastic devices, reduce insulationIn this case, the control box shall be made into a closed structure and ventilated.
Q:The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?
The power over voltage means that the DC bus voltage exceeds the rated value because the voltage of the supply is too high. Now, most inverters have an input voltage of up to 460V, so the overvoltage caused by power supply is extremely rare. The main issue discussed in this paper is the regenerative overvoltage. The regenerative overvoltage mainly has the following reasons: when the big GD2 (flywheel moment) load slows down, the inverter deceleration time is set too short;
Q:What does Ro1c mean on a converter?
Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.
Q:How does MM430 frequency converter always report F003 fault?
To solve the problem, then check the original power of the line is loose, the power cables are quickly burnt, after fastening normal, thank you enthusiastic support, thank you!
Q:Heating inverter commissioning steps
The no-load connection test of the frequency converter will connect the grounding terminal of the frequency converter to the ground 1. 2 the power input terminal of the frequency converter is connected to the power supply through the leakage protection switch. 3 check the frequency converter display window factory display is normal, if not correct, should reset, or request exchange. 4 familiar with the operation key of frequency converter. The inverter has run in general (RUN) and stop (STOP), programming (PROG), P (DATAPENTER), the data confirm the increased (UP, 3), reduce (DOWN, 6) and other key definitions of different inverter operation keys are basically the same. In addition, some inverters also monitor (MONITORPDISPLAY), reset (RESET), inch movement (JOG), shift (SHIFT) and other functional keys.
Q:Can not directly through the PLC, ABB converter and Kingview software communication between them?
As long as there are 485 communications can be, the frequency converter manual on the MODBUS protocol, the address of each parameter, in the king view on the link can do, and I hope to adopt.
Q:What are the differences between electronic governor and frequency converter in motor speed regulation?
Inverter is to realize the speed adjustment of AC asynchronous motor by changing the motor power supply frequency, speed adjustment and balance, load property of the motor does not change with changes in speed, suitable for load adjustment and torque adjustment. Good performance, but high cost.
Q:Frequency converter closed loop control, frequency converter must use PG card?
Mainly depends on what you want closed loopIf it is speed closed-loop, with PLC, you can not use PG card, direct PLC acquisition speed as a negative feedback signalIf it is a closed loop of ordinary process variables, such as pressure, temperature, etc.Neither PLC nor PG cards are requiredThe PG card is mainly used in the speed closed loop of the converter to collect signals
Q:What does "EPCU" mean in a frequency converter?
This is the frequency converter BlueOcean Huateng, they said this code external signal interference, you are not the power line and the signal line to go ah, check the external line, then no problem on the phone to the factory
Q:What does the brake unit on the inverter mean?
When the motor is fast stopping, the motor will feedback the energy to the converter, causing the DC bus voltage to rise or even damage the IGBT. Therefore, it is necessary to use the braking unit to save the part of the energy to protect the converter.Inverter braking a lot, can refer to:
