Reference! Quality standards for the operation of INVT's inverters

  According to Invitro Drive brand standards are different The details of the quality requirements of the product should be different. The following are just some basic references:

1. Acquisition specifications of the inverter<1>1. Ensure that the selected inverter matches the motor used. Specification. 2, no ventilation equipment to ensure the inverter cooling function during operation. 3. The package level of the inverter is B or higher. 4. A reactor must be added to the input and output terminals. 5. Ensure that the inverter terminals and internal components are intact. 6. Ensure that the appearance of the inverter is intact.

Second, the quality specification of the inverter when running. 1. Ensure that the inverter does not have any negative influence on the control circuit and the peripheral equipment of the machine when it is in use. Divided into the following parts:
A, does not affect the temperature control input signal part of the main controller. The method is to look at the frequency conversion condition when the temperature control display data of the panel and the power frequency condition are the same. B. Does not affect the position input signal of the main controller. The method is to look at the frequency conversion condition when the panel's ruler appearance data and the power frequency condition appear the same. C. Does not affect the flow rate and pressure output signal of the main controller. The way to look at the frequency and pressure of the ammeter is the same when the data shows the data and power frequency conditions. D. Does not affect the variable frequency control output signal of the main controller. The method is to see the frequency conversion control voltage signal output by the main controller and the frequency to be output by the inverter when looking at the frequency conversion condition. E. Does not affect the internal circuit of the main controller. The method is to see if the IC components of the main controller are abnormal under the condition of frequency conversion. F. Does not affect the equipment of the week. Look at the actual work, if the equipment around the week is controlled by the analog input and output signals, see if there is any impact. 2. Make sure that the inverter anchor point does not affect the temperature rise of the motor when it is in use. The method is to look at the frequency conversion condition when the panel motor temperature rise appears and the power frequency condition is the same. 3. Ensure that the inverter does not affect the machine cycle when it is in use. The method is to look at the frequency conversion condition when the panel cycle period shows the data and the power frequency condition is the same. 4. Ensure that the inverter does not affect the response speed of the machine when it is in use. The method is the same as when the response speed and power frequency of the manual operation are the same when looking at the inverter condition. 5. Ensure that the inverter does not affect the stability of the hydraulic system of the machine when it is in use. The solution is to look at the frequency of the hydraulic shock and power frequency conditions of the same action. 6. Test whether the three current outputs of the inverter are balanced. The method is to use the clamp type meter to measure whether the current output of each item is balanced at 20HZ, 30HZ, 40HZ, 50HZ. 7. It is required to be neat and refreshing on the inverter machine. 8. In electrical wiring, it is required to be completely constructed according to the drawings. It is required to fasten all the screws on the fixed connection, and the fixed screws are not allowed to loosen. The electrical component device is simple and clear, and the cable is neat.
