What is the fault of ABB inverter ACS401000432 flashing red light?

It looks like an ABB inverter ACS401....You don't have an indicator light, right? "I'm sorry, I've only used ACS50 and other series".

How do you set it up? What is the type of signal you set to be the indicator, and what is it, and what is the problem? It's not easy to conclude that you haven't seen the actual thing.

Or maybe it's an overcurrent, or maybe the cooling fan is broken. Or see if there is a fault on the disk of the inverter!

The 400 machine is an off-line product, a disc is worth more than 1000, you see that it can be reset, if not, measure its main circuit, if the main circuit is broken, I suggest that you replace the ACS510 can be completely replaced!

ACS400 removed the panel to see the indicator.

A flashing red light is an alarm, not a malfunction.

Since you can see the instructions, etc., if you don't set up a panelless operation, the most likely thing is that the control panel is lost alarm.

As for the other alarms, you can only know when you plug in the panel.

See if there is a fault on the disk of the inverter!

The 400 machine is an off-line product, and a plate is worth more than 1000.

If you can't, measure its main circuit, if the main circuit is broken, I suggest you replace the ACS510 to completely replace it!

It could be an overcurrent or a broken cooling fan.

The ABB inverter shows that the 2330 is ground fault protected.

When selecting the power of the inverter, it is necessary to pay attention to:

1. When the power value of the inverter is equivalent to the power value of the motor, it is most suitable to facilitate the operation of the inverter under high efficiency value.

2. When the power classification of the inverter is not the same as the power classification of the motor, the power of the inverter should be as close as possible to the power of the motor, but it should be slightly greater than the power of the motor.

3. When the motor is frequently started and braked or is in heavy load starting and working frequently, a larger inverter can be selected to use the inverter for long-term and safe operation.

4. After testing, the actual power of the motor does have a surplus, and the inverter with a power less than the power of the motor can be considered, but it is necessary to pay attention to whether the instantaneous peak current will cause overcurrent protection action.

5. When the power of the inverter and the motor are not the same, the setting of the energy-saving program must be adjusted accordingly to achieve a higher energy-saving effect.

First replace the spare IGBT, replace it with a group of three, and check whether the driver board has any burnt spots.

Fault **2340: Short-circuit current detected in a non-parallel connected drive unit; The output current is too large;

The focus is on the inverter module. It should be the IGBT failure of the inverter itself.

ABBACS800 inverter parameter setting:

Define the connections and signal sources for start, stop, and steering commands using Ext1. di1fdi2r。

It is allowed to change the steering of the motor, or to fix the steering. request。

Select an external source for a given ref1. ai2。

Define the minimum (absolute) value of a given ref1 externally. Equivalent to the minimum setpoint of the signal source used. 0?18000rpm。

Define the maximum (absolute) value of a given ref1 externally. Equivalent to the maximum setpoint of the signal source used. 0?18000rpm。

Defines the minimum value of analog input AI1. When used as a given value, its value corresponds to the minimum given set value. For example, if ai1 is used as a signal source for an externally given ref1, its value corresponds to the value of the parameter.

Defines the maximum value of simulated input AI2. When used as a given value, its value corresponds to the maximum given set value. For example, if ai1 is used as a signal source for an externally given ref1, its value corresponds to the value of the parameter. 20ma。

Select the transmission state displayed by the relay output RO2, and the relay will be energized when the state meets the set conditions. running。

Select the transmission state displayed by the relay output RO3, and the relay will be in the energized state when the state meets the set conditions. fault。

Select a transmission signal to the analog output.

It is a temperature failure, the cause of the failure.

1. The cause of the fault is that the power plug is not plugged in properly.

Solution: Check and plug in the power plug.

2. The sensor is damaged and the resistance value is wrong.

Solution: Replace the sensor.

3. The fuse is burned.

Solution: Repair and replace the fuse.

ABB ACS800 drives reported 4280 failures because the inverter-cooled fans had been running for longer than the estimated life expectancy and required the fans to be replaced. You can enter the password 2303 (standard type) or 2289 (system type) in the parameter setting, and then change the parameter to 0 to set the time of the fan to zero.

If the wind turbine time exceeds the estimated life, you can view the number of hours the wind turbine has been running. After replacing the fan, enter the password 2303 (standard type) or 2289 (system type) for parameter setting, turn on the hidden parameters, and then enter the quick down arrow to reduce this value to 0 (it takes a long time). When the RMIO is powered off, check whether the reset is successful after powering it on again.

If the value is changed back to the previous value, the reset fails, and the above operations are repeated until the reset is successful.

Summary. ABB ACS800 Alarm Short Circ (2340) * Motor cable or motor short circuit. Inspect the motor and motor cables.

Check the motor cable for power factor correction capacitors or surge absorbers. The output bridge of the inverter is faulty. Because the phenomenon you are talking about is:

After resetting, it will start and run normally, and after a period of time, it will alarm 2340. So you need to check the motor and motor cable carefully.

ABB inverter ACS800 alarm 2340, reset and then start to run normally, after a period of time alarm 2340, what to do?

ABB ACS800 Alarm Short Circ (2340) * Motor cable or motor short circuit. Inspect the motor and motor cables. Check the motor cable for power factor correction capacitors or surge absorbers.

The output bridge of the inverter is faulty. Because the phenomenon of your spine rot is: after the reset and then start to run normally, after a period of time, the alarm is 2340.

So you need to check the motor and motor cable carefully.

This failure does not occur frequently, and sometimes it takes working hours to report the failure once.

What's going on?

What causes it?

Summary. The name of the parameter, where f0 is the name of the primary parameter and 00 is the secondary parameter.

The inverter shows F000, the panel buttons are not responding, and there is a hardware problem. According to your description, power back on first, if the fault persists, you need to disconnect the output and power on again, which means that the output is loaded. If there is a writing device, the program can be rewritten.

If you can't do it, you can only go back to the repair factory.

There may also be interference caused by the power supply of the inverter, or the hardware of the inverter itself, etc., which needs to be confirmed by professionals.

Hello, I have seen your question and am sorting out the answer, please wait a while The name of the parameter, f0 is the name of the primary parameter, and 00 is the secondary parameter.

According to your description, power back on first, if the fault persists, you need to disconnect the output and power on again, which means that the output is loaded.

ABB inverter alarm f0000 what is the fault Hello dear, overcurrent protection. It may be the fault of the inverter itself, or it may be the fault of the external line. You power off and restart to try and see if it can work.

Or remove the output U2 V2 W2 to start it to see if it can be normal, if it is not normal, the inverter itself is broken. If it is dismantled normally, it may be that there is a problem with the wiring on the side of the motor. Hope it helps.
