1. What are the factory parameters of inverter rehabilitation?
N600 = 100 (often press the WR button for 3-5 seconds), it is necessary to be in the shutdown state to be effective.
2. In the parameters of the N308 motor of the inverter, is the specified sub-leakage inductance reactance or rotor leakage inductance?
Stator leakage reactance = rotor leakage reactance = motor leakage reactance
3. Can the inverter check the previous fault information?
Yes, for example RNB6000 it is possible to check the last 8 faulty code information through parameter N603.
4. RNB6000 the N701-N712 parameter specification, but I can't see it in the inverter?
N701-N712 is the default hiding group parameter, set N700=7
5. RNB6000 the parameters of the motor should be entered correctly before starting?
Because the RNB6000 inverter completes the better control of the motor inside the motor, and a special algorithm is added to achieve better control effect, so it is necessary to correctly input the parameters on the motor sign. Otherwise, there will be a phenomenon such as starting over the current or the frequency cannot be increased.
6. How to set the external analog input of RNB6000 inverter 0-20MA and 4-20MA?
RNB6000 type can input 0-20MA and 4-20MA externally, after the internal parameter N222=0% is 0-20MA input, N222=25% is 4-20MA input.
7. Can the RNB6000 inverter complete the given switching between the main frequency and the auxiliary frequency source?
The RNB6000 type inverter is perhaps connected to the external terminal X1 (12). X2 (13) terminals. The X3(14) terminal completes the frequency switching by binary combination (e.g., parameter N203=15.N204=16.N205=17). The default frequency is given by N002 and can be switched when the multi-function terminal is connected to the COM(20) terminal (the priority of the terminal is higher than that of N002).
8. What is the difference between the RNB6000's motor tuning N311=1 (static self-learning) and N311=2 (dynamic self-learning)?
RNB6000's N311=1 static self-learning learns the resistance and resistance leakage inductance of the motor, and rewrites the internal parameters N306.N308.N309. values, and N311=2 dynamic learning is self-learning of the no-load current and motor mutual inductance of the motor, and rewrites N307.N310.N403, and the parameters of dynamic learning are more comprehensive (it is recommended to use the method of dynamic learning).
9. How to set the analog output of RNB6000 inverter to 0-10VDC, 0-20MA and 4-20MA?
THE RNB6000 CAN OUTPUT 0-10VDC AND 0-20MA/4-20MA OUTPUT SIGNALS EXTERNALLY, AND THE HARDWARE PART IS SELECTED BY TWO DIP SWITCHES ON AM1 AND AM2 ON THE MOTHERBOARD (CURRENT/VOLTAGE IS SELECTED), AND THEN THE 0-20MA OUTPUT IS SET TO 0% WHEN THE PARAMETERS N226 (AM1 CHANNEL) N228 (AM2 CHANNEL) ARE SELECTED. 4-20MA OUTPUT: 25%.
10. How to complete heavy-duty control (vector control) of RNB6000-type inverter.
To complete the vector control, you need to correctly input the parameters on the motor name plate (motor current, speed, pole pair), and then put N311=2 (dynamic self-learning), and then take the empty motor, start (inverter start learning) to identify the motor parameters, after learning, and then N008=4 can be.
11. How many relay dry contact outputs are supplied to the RNB6000 inverter?
The RNB6000 type is supplied with two relay dry contact outputs, which are 11.21 (NO point), 01.02.03 (normally open, normally closed) outputs, and one transistor output.
