1. What does it mean to restore the inverter to factory settings?
FP-01=1
2. In the motor parameters of inverter F1, does "motor leakage inductance reactance" refer to the rotor leakage inductance reactance or the inductor leakage inductance reactance?
Stator leakage reactance = Rotor leakage reactance = Motor leakage reactance
3. Can the inverter's previous fault information be viewed?
Yes, for example, you can view the information of the three most recent fault codes for the MD380 using parameters F9-14 to F9-17.
4. The parameters for Group A of the MD200 are in the instruction manual, but I can't see them in the inverter?
Group A0 is the default hidden group parameter. You can set FP-02=111 (the tens digit is the display of group A parameters, and the units digit is the display of group U parameters; FP-02 is 1 by default).
5. The MD300 manual only lists 0-3 for F0-13 (DO output selection). Why does the inverter have an option 4?
The MD300's 14#FDT function is a non-standard feature with function 4: FDT function selection.
6. How are the two taper modes (FH-65, taper mode) calculated in MD330?
1. The taper of the curve FH-65=0 is based on the curve F=F0(1-K*(D0+D1)/(D+D1)).
2. The straight taper of FH-65-1 is determined according to the taper inflection point and tension taper of FH-61 to FH-64;
3. Note: FH-09 (tension taper) in MD330 is only applicable to the winding mode.
7. What is the difference between 0/1 in function codes F0-03 (Main Frequency Source X Selection) and 0/1 in F0-23 (Digital Setting Frequency Stop Memory Selection) in MD380/MD500?
F0-03=0 indicates a digitally set frequency that is not remembered after power failure.
F0-03=1 indicates the digitally set frequency, which is remembered after power failure.
F0-23=0 indicates that the frequency setting is not remembered when the machine is stopped.
F0-23=1 indicates the frequency of the shutdown memory digital setting.
8. What is the difference between F1-37=3 (static self-learning 2) and F1-37=1 (static self-learning 1) in the motor tuning of the MD380?
The MD380 features a "Static Self-Learning 2" function, which is suitable for self-learning motor parameters when the motor is stationary and there is no encoder. In this case, the motor may still vibrate slightly, so safety precautions should be taken.
9. What is the difference between U0-19 (feedback speed) and U0-29 (encoder feedback speed) on the MD380? Do they display frequency or speed?
U0-19 is the inverter output frequency, and U0-29 is the actual motor frequency fed back by the encoder. Both display the frequency.
10. In the MD380 parameters, what is the difference between U0-45 (fault information) and U0-62 (current fault code)?
U0-45 refers to the fault information code, such as communication fault code 16; U0-62 is the fault sub-code, which is a sub-fault of the fault information.
11. Why are the parameters for group U1 on the MD380M not displayed, making it impossible to monitor?
The parameters of group U1 will only be displayed after U1-06=1. (Note: U1-06 will be set to 1 after the origin is found.)
12. How to set the relay function in CS700 to normally open or normally closed?
Normally open or normally closed is distinguished by the hundreds digit of function codes B3.14-B3.20, where 0 represents normally open and 1 represents normally closed.
