What does it mean for Siemens inverter m430 to report fault F011

1. F0011 fault indicates that the motor is overheated.

2. Possible causes of failure: motor overload, check the following:

1.The working gap period of the load must be correct.

2.The nominal motor temperature overrun (P0626 P0628) must be correct3Motor temperature alarm level.

p0604) must match If p0601=0 or 1, check the following:

1.Check the nameplate.

Whether the data is correct (if you don't do a quick debugging).

2.By using the method of automatic detection of motor parameters (P1910=1), accurate equivalent circuit data can be obtained.

3.Check whether the weight of the motor (P0344) is reasonable, and modify it if necessary4If you are using a motor that is not a standard motor from Siemens, please modify the data of the over-temperature protection with parameters P0626, P0627, P0628.

3. Inverter.

Variable-Frequency Drive (VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. The inverter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit, microprocessor unit, etc. The inverter relies on the interruption of the internal IGBT to adjust the voltage and frequency of the output power supply, and provides the required power supply voltage according to the actual needs of the motor, so as to achieve the purpose of energy saving and speed regulation.

With the continuous improvement of industrial automation, frequency converters have also been widely used.

There is a temperature sensor on the heat sink to check if it is broken.

The fault information F0023 of Siemens inverter MM440 indicates that the output of the inverter is faulty, and the output is disconnected. There may be several reasons for this failure:

When the Siemens inverter MM440 prompts the F0023 fault alarm, the user needs to check the following items:

1) Check whether the output terminal of the inverter, the motor terminal and the motor cable are firmly connected and whether the cable is disconnected. If the wiring is loose, the wiring needs to be tightened, and if the cable is disconnected, a new connecting cable needs to be replaced;

2) Check the empty opening of the output side, whether the contactor is disconnected or damaged;

3) Check whether the contactor control timing is correct;

Indicates that there is a problem with its board.

Frequency transformer is generally an electrical energy control device that uses the on-off effect of power semiconductor devices to convert the power supply of power frequency to another frequency. The main circuit of the inverter can be roughly divided into two categories: the voltage type is the inverter that converts the DC of the voltage source into AC, and the filter of the DC loop is capacitor; The current type is an inverter that converts the DC of the current source into AC, and its DC loop filter is an inductor.

Check the fault of the manual**, if it is a problem with the circuit board, then you need professional equipment to detect.

Siemens inverter F0003 alarm is undervoltage. The main causes of failure are:

1. Power supply failure.

2. The impact load exceeds the specified limit value.

Check the following items for processing:

1. The power supply voltage P0210 must be on the nameplate of the inverter.

within the prescribed range;

2. Check whether the power supply is power-off for a short time or has an instantaneous voltage drop, and enable it.

dynamic buffering p1240=2;

Generally speaking, when encountering a failure of Siemens inverter, the multimeter should be used first before powering on.

Check out the rectifier bridge.

and whether the IGBT module is burned, and whether there are obvious traces of burn on the circuit board. If the module is damaged, it cannot be blindly powered on, especially when the rectifier bridge is damaged or there are obvious traces of burning on the circuit board, it is especially forbidden to power on, so as not to cause greater losses.

Siemens inverter fault**F30004 What is the reason for the power unit to report F30004 fault solving and repair, common fault repair: temperature fault Grounding fault, power component failure, burning fuse, tripping, explosion, undervoltage, overcurrent, no DC600V DC output, yellow light is not on, indicator light is not on at all, red light is on, with immovable load, circuit board burned, output given instructions are not working, display alarm is not ready, servo drive failure, encoder alarm, DP communication failure, X-axis failure, The Y-axis does not work, the Z-axis is not enabled, and the system reports 380500,

Most of them are unstable power supply or power supply harmonics at the incoming end.

interference. Workaround:

You can add an incoming filter, or an incoming reactor.

to suppress harmonics. If it is caused by harmonics, you can add an incoming filter or an incoming reactor to suppress the harmonics; There is also the possibility that the inverter is a hardware fault of the inverter, such as a voltage detection loop.

Then, the acceleration current is limited to the overcurrent capacity of the inverter, so as not to cause the inverter to trip due to the overrun. The key points of the deceleration time setting are: to prevent the smooth circuit voltage from being too large, and not to cause the regenerative overvoltage to stall and trip the inverter. The acceleration and deceleration time can be adjusted according to the load.

It is calculated, but in the debugging, it is often taken to set a long acceleration and deceleration time according to the load and experience, and observe whether there is an over-current and over-voltage alarm through the start and stop motors; Then, the acceleration and deceleration setting time is gradually shortened, and the optimal acceleration and deceleration time can be determined by repeating the operation several times in the principle that no alarm occurs during operation.
