How to solve the problem of Delta inverter VFD G boot display EF?

This situation should be a problem with the system, in this case, it should be okay to reboot, if not, you can replace the circuit board.

When the external terminal EF is closed, the AC motor driver stops out. To clear the fault**, press the reset key to reset.

How to solve the problem of Delta's inverter displaying EF for bar fine booting? It's like this, you press the power supply and um switch for 30 seconds to cancel this EF.

Click Restore on the main page of the inverter to lock the system interface and keep it running normally.

If this happens when he boots up, it must be when his system or monitor has a certain failure, and he must remember to deal with the maintenance.

So if it is said that the display corresponds to those ** after booting, it may be because of the problem of which displays correspond to that parameter, so in many cases, these adjustment states can be corresponded to through some internal hardware.

With such display parameters, we need to see the problem of comparing the parameter fault display to find the boot.

Generally, such faults are caused by short circuits in the circuit.

Maybe you didn't set the parameters, or the parameters didn't match the motor.

Summary. How to restore the factory settings of Delta's VFD-B series inverter: Set the value of parameter 00-02 (parameter resetting) to 09, save, and the setting of all parameters will be restored to the factory value. 

Delta's VFD-EL inverter is restored to factory settings.

How to restore the factory settings of Delta's VFD-B series inverter: Set the value of parameter 00-02 (parameter resetting) to 09, save, and the setting of all parameters will be restored to the factory value. 

Delta's inverter is factory reset as follows: Set value to 9 or 10: Factory set value can be restored.

If you have set a password (parameter 00-08), you must decode it first (parameter 00-07) and clear the original password before restoring the factory value. Detailed description of Delta inverter parameters: factory setting value:

0 set range 0: no function 1: parameter write protection 5:

Invalid panel operation9: Parameter reset (base frequency is 50 Hz)10: Parameter reset (base frequency is 60 Hz)11:

Parameter reset (base frequency is 50 Hz, and the parameter 13-01 13-50 is saved, and the user can define the parameters and settings.) 12: Parameter reset (the base frequency is 60 Hz, and the parameter 13-01 13-50 is saved, and the user can customize the meaning parameters and setting values.)

Set value to 1: only parameters 00-02, 00-07, 00-08 can be set, other parameters are only read-only, parameter 00-02 must be set to 0 before other parameter settings can be changed. The set value is 5:

The displayed value of the calculated kWh inside the inverter can be cleared during operation, and the displayed values of parameters 05-26, 05-27, 05-28, 05-29 and 05-30 can be zeroed out. Set value 6: Clear the internal PLC program (including the settings related to the internal CANopen master of the PLC).

to restore the factory settings. If you have set a password (parameter 00-08), you must decode it first (parameter 00-07) and clear the original password before restoring the factory value. When the setting value is , please power it back on again after the setting is complete.

Summary. Hello, the following is a little sister to solve your doubts for you, I hope it can help you.

Dear, the method of restoring the factory settings of the inverter VFD-M is as follows:

1. Press the prog data key to enter the parameter menu, unlock it in the 00-07 and 00-08 parameters, if there is no password to omit, then adjust the parameter 00-02 to 09 and then save, you can restore the factory settings.

2. Press and hold the Enter key on the panel for ten seconds after the inverter is powered on, and then turn down the page to find P76 after displaying P00.

I really hope I can help you, and I wish you happiness every day!

How to adjust the speed of Delta's inverter VFD-EL.

Hello dear, adjusting the speed of Delta's inverter VFD-EL requires the following operations: 1Enter the parameter adjustment mode.

Press and hold the mode button for 3 seconds, and "rd--" will appear on the digital tube, and then enter the parameter adjustment mode. 2.Adjust the parameters.

Press the up or down key to switch to parameter 004-fr1 (frequency limit 1). 3.Enter an adjustment value.

Use the numeric keypad to enter the frequency value that needs to be set, such as 120Hz, and type . 4.Save the hail notes.

After the parameter setting is completed, press the mode button once to complete the parameter setting. 5.Set the control mode.

Press the mode button once to switch to par-. 6.Set it to one of the manual automatic control modes.

Switch to manual auto mode by entering the number (01 - manual control, 02 - automatic control). After the setting is complete, press the mode button to save. 7.

Check the settings. Use the up or down key to navigate through the set parameters to confirm whether the settings are correct. The above are the basic adjustment steps, which can be adjusted according to the specific situation.

It should be noted that when making parameter adjustments, the operator needs to know the relevant knowledge to make the correct adjustments, otherwise it may lead to premature combustion failures in the machine. Therefore, it is recommended that beginners refer to the manual and relevant training materials first, and then adjust after mastering the relevant knowledge.

Delta's VFD-F inverter shows that FF12 is a ground fault. Check whether the line to the motor is damaged and grounded. Cause Analysis:

When the AC motor driver detects that the output terminal is grounded and the grounding current is greater than 50% of the rated current of the AC motor driver, it should be noted that this protection is for the AC motor driver and not for the human body. Solution: 1. Check whether the connection with the motor is short-circuited or grounded.

2. Determine whether the IGBT power module is damaged. 3. Check whether the wiring on the output side is poorly insulated.

Summary. When restoring the parameters to factory values, you can set the parameters to 9 or 10 to restore the factory settings.

The parameter selection is between zero zero and zero two.

If you have a password, you must decipher the password before restoring the factory value and erasing the password.

How to force the factory reset of all the VFD-W buttons of Delta's inverter?

When restoring the factory value of the parameter Hail Royal, you can set the parameter to nine or ten to restore the factory settings. The parameter is between zero zero and zero two. If you have a password, you must decipher the password before restoring the factory value and erasing the password.

You're talking about Delta's inverter, which controls the operation of the motor, and one or more Dushan is simply inspected. It's not a failure, it's a way of controlling the command. It is divided into panel controls.

When changed to external control, 0-10V, the operation command ** is also external control, and it is invalid for the panel to set stop. That panel is useless, it can only show the frequency. That's locked.

Prevent mispresses and random changes to the program. There is it in the manual, and it can be changed back.

All the keys are out of order, the setting keys are all out of order, and you can't get in.

It may be that the manufacturer has locked the panel, and you have no permission to change any parameters and operation modes! Contact the manufacturer who sold you the equipment!

Finished? When you want to restore the parameters to the factory value, the roller shed can set the participating nuance number {00-02} to "9" or "10" to restore the factory set value. If there is a mess of the password, you must decode it before restoring the factory value, and at the same time the password will be cleared. <>
