1. Use of inverter operation panel
As a man-machine interface, the inverter operation panel is the main unit for the inverter to accept commands and display parameters.
Figure 1 Operation panel
2. Inverter operation panel key functions The inverter operation panel has 7 keys and 1 knob. The function definition is shown in Table 1.
Table 1 Control Panel Key Function Table
3. Indications of the indicator on the inverter's operation panel The inverter's operation panel is equipped with 6 indicator lights. The indicating function of each indicator light is shown in Table 2.

4. Inverter panel potentiometer given instructions The inverter panel potentiometer can be given as frequency reference and process PID, and is set through the setting of relevant function code. When b0-01 is set to 3 (setting method parameter), the panel potentiometer of the inverter is the main frequency reference. B0-03 is set to 4, the panel potentiometer is a secondary frequency reference. When b1-01 has one, ten or one hundred places set to 4, the panel potentiometer is used as the frequency given binding mode of the corresponding command channel. Inverter panel potentiometer is process PIDGiven the timing, set F0-00 to 2.
5. Inverter prompt information status Some operations will display prompt information status. For example, when the factory parameters (including the motor) are restored, the "dEFt2" message status will be entered.
Refer to Table 3 for the meaning of the prompt message character and each character.

6. Inverter function code parameter setting method (1) Function code system Inverter function code group: A0, b0 ~ b2, C0 ~ C4, d0 ~ d2, E0 ~ E1, F0 ~ F1, H0, L0 ~ L1, U0 ~ U1, Each function code group includes several function codes. The function code is identified by means of "function code group number + function code subgroup number + function code number". For example, "F1-07" indicates the function code No. 7 of the first group function of group F.
(2) Display structure of function code The function code and its parameters adopt a secondary structure. The function code corresponds to one-level display, and the function code parameter corresponds to two-level display.
Level 1 is shown in Figure 2, Level 2 is shown in Figure 3:
Figure 2 function code level display
Figure 3 shows the function code secondary display (3 is the contents of b0-00)
Product Description
The combined pad mounted transformer places the transformer body, high-voltage load switch, fuse and other components in the transformer oil tank together. Because of being immersed in oil, the component volume is greatly reduced, the structure is more compact, and the installation is convenient and flexible. Fully insulated, fully sealed structure, safe and reliable, easy to operate, maintenance free. It is widely used in residential areas, high industry centers, factories and mining enterprises, airports, stations, schools and other places.
Characteristics of pad mounted transformer
1. Compact structure, small volume, convenient and flexible installation;
2 Fully insulated and sealed structure, safe and reliable, maintenance free, and reliable protection of personal safety;
3 The high-voltage side is protected by double fuses, in which the plug-in fuse is a double sensitive fuse (temperature and current) and the backup fuse is a current limiting fuse, reducing the operating cost;
4 High voltage incoming line adopts cable connector structure, which is fully insulated, safe and reliable, and easy to operate;
5 It can be used for both ring network and terminal. It is very convenient for conversion and improves the reliability of power supply
6 The transformer is a three-phase three column structure, and the iron core adopts the stepped joint process, which has low noise, low loss, and strong short-circuit and overload resistance.
7 The box can adopt anti-corrosion design and special painting treatment according to the requirements of the operating environment. It has the "three prevention" functions, namely, anti condensation, anti salt fog, and anti mold functions, and can meet the anti-corrosion requirements under high temperature and high humidity environments.
