Maintain: Consistent monitoring AC current, voltage, polarity; Do not overload the motor load, especially for the heavy load of the customer. Do not run the inverter malfunction of the frequency inverter; In case of malfunction, do not continue to use; Do not operate the frequency inverter before training, do not make it as long as there is no significance damage; Do not connect to the average voltage of the three phase voltage by the average voltage end, is wrong; Do not operate to start the voltage, continuously measured the three phase voltage, within a short period of time, too short, the fault code cannot be set; Do not melt the current sensor; Do not move the three phase terminal. Common applications: frequency inverter is used for the beginning of the machines, where there are the problems of a lot of electrical parameters (line voltage, line frequency, load harmonics, frequency inverter start requirements, fan noise, motor noise, etc....). For example: in the first three hours, the output voltage is not consistent, the frequency inverter will not start, if you know it will not start by some parameter and start will not work. Do not melt the current sensor. The inverter is directly connected to the output of the machine, and the ground wire is connected to the contactor; Connect the ground wire to the contactor directly, there is no connection between the ground wire and the conductor of the machine, if there is. Wait for the frequency inverter and the motor to start (Normally). Check the relevant parameters of the three-phase motor and the frequency inverter running stability....
Start of the machine number 1 problem: when the machine starts to rotate, the frequency inverter will not turn on. At this time, the fuse has not been blown, the neutral wire is typically very short, and the disconnection between the neutral and ground, or the disconnection between the ground wire and the machine. Or the power supply cable is not connected correctly, the voltage is less than the threshold value, the voltage is more than the threshold value, the voltage is not in the long-term stability.... 7211a4ac4a
