How does a Siemens inverter simulate a fault 10

Look at the manual, there is a fault input point, and the fault will be reported when it is connected!

As follows:

1. ** F0001: overcurrent.

2. ** F0002: overcurrent.

3. ** F0003: Undervoltage.

4. ** F0004: Overheating.

5. ** F0022: Power component failure.

6. ** F0054: I-O board error.

1. For the debugging of Siemens 440 inverter, some initial states of the inverter should be confirmed first, after confirming the connection between the motor and the inverter, the internal control is used to control the rotation of the motor with the operator first, and the following parameters need to be set first: P0003=3, P0700=1, P1070=1050. Once the settings are complete, you can hand over the operation to the operator.

2. The Siemens 440 inverter with an integrated brake chopper works with outstanding precision even during braking and short deceleration ramps. All of this is possible in the power range from kW (hp) up to 250 kW (350 hp).

3. Siemens 440 inverter uses the on-off effect of power semiconductor devices to turn the AC power with fixed voltage and frequency into an AC power supply with adjustable voltage and frequency. It is composed of a main circuit and a control band circuit. The main circuit is the power conversion part that provides controllable power supply to the asynchronous motor, and the main circuit of the inverter is divided into two categories, in which the voltage type is the inverter that converts the DC of the voltage source into AC, and the filtering part of the DC circuit is the capacitor.

Summary. Hello, Siemens inverter alarm: the motor cannot be detected, there is a solution:

When the A501 overcurrent phenomenon occurs in the V20 inverter, the following items need to be checked according to the 1-3 items of the fault cause: 1. The motor power (P0307) must be consistent with the power of the inverter (R0206). 2. There shall be no short circuit or grounding fault inside the motor cable and motor.

3. The length of the cable shall not exceed the allowable limit value. 4. The stator resistance value (P0350) must be correct. 5. The motor shall not be stalled or overloaded.

6. The motor parameters must match the actual motor used. 7, reduce the starting lifting strength 8, increase the ramp rising time (P1120).

Siemens inverter alarm: the motor cannot be detected.

Hello, Siemens inverter trapped bending alarm: can not detect the motor, there is the following solution: when the V20 inverter appears A501 overcurrent phenomenon, according to the fault cause of 1-3 items, you need to check the following items:

1. The motor power (P0307) must be consistent with the inverter power (R0206). 2. There shall be no short circuit or grounding fault inside the motor cable and motor. 3. The length of the cable shall not exceed the allowable limit value.

4. The stator resistance value (P0350) must be correct. 5. The motor shall not be stalled or overloaded. 6. The motor parameters must match the actual motor used.

7, reduce the starting lifting strength 8, increase the ramp rising time (P1120).

Summary. The main reason is that the voltage of the main circuit is too low (380V series is lower than 400V), the main reason: damage to a certain circuit of the rectifier bridge or abnormal operation of the three channels of the thyristor may lead to the occurrence of undervoltage fault, and secondly, the main circuit contactor is damaged, resulting in the voltage loss of the DC bus on the charging resistor, which may lead to undervoltage.

There is also the problem of undervoltage due to the failure of the voltage detection circuit.

The main reason is that the main circuit voltage is too low (380V series is lower than 400V), the main reason: a certain way of the rectifier bridge is damaged or the thyristor three-way search wheel is not working properly, which may lead to the occurrence of undervoltage faults, and secondly, the main circuit contactor is damaged, resulting in DC bus voltage loss on the charging resistor, which may lead to undervoltage. There is also the problem of undervoltage due to the failure of the voltage detection circuit.

Siemens inverter F0006 fault information: The device is shut down due to the high voltage of the DC bus. Please check the power supply voltage or the input DC voltage.

Due to the high voltage of the DC bus, the installation Qingxian shut down 1, and the filter capacitor of the inverter failed to praise the code. 2. If the deceleration time of the inverter is too short or sudden braking, you can consider increasing the deceleration time and increasing the braking resistance if necessary. The copyright is changed to Zhiwanshi** or the original author Zhou 3, the old source voltage of the electric model is high (the probability is small) in front of the point of the public Tong Tunong West to change the breeze, with a wide range of selection and writing.

Under-voltage fault solution: 1. Check whether the input power supply is out of phase 2. Check whether the input power supply voltage is too old and low 3. Check whether the rectifier module is low imitation effect (inverter maintenance professional engineer can detect) 4. If there is no problem with the above, that is, the voltage detection circuit of the power strip is aging or burned.

The input power supply is not out of phase, and the voltage is 410 volts.

The DC bus power supply is not measured.

The line voltage of the three-phase power supply 50Hz power supply is 380V, generally floating within 5%--5% has no impact on the equipment, and the voltage of 410V is a little higher.

Preparation: Shut down and power off. Check that the equipment and the surrounding environment are in good condition to ensure that it is safe and orderly during maintenance.

2.Cleaning: Thoroughly clean the surface of the device with an appropriate detergent.

During this process, damaged, deformed, or worn parts can be noted. If necessary, extract replacement parts from the spare parts warehouse, and make a record of the mountain after replacement. 3.

Inspection: Check that all measurements, control parameters, and maintenance checklists of the equipment are within the standard range to determine if the calibration equipment needs to be replaced or reburied during maintenance. Electronic components, wiring and terminal points must be inspected for corrosion and cleaned and replaced accordingly.

Hello Dear I am very happy to answer this question for you, the common faults of Siemens inverter ** are as follows: F0001 means that the power of the motor and the power of the inverter are not adaptable, and it is necessary to replace Dongchang pants with a frequency converter with the same power as the motor; F0002 means that the DC circuit voltage of the motor exceeds the rated value of the inverter, resulting in the inverter's inability to work; F0003 indicates the undervoltage of the inverter, and when this happens, the power supply of the inverter is generally faulty; F0004 means that the temperature of the inverter is too high, and it is necessary to suspend the use for a period of time to reduce the temperature of the speed, or install a cold fan for the inverter to maintain the temperature; F0005 indicates that the intermittent cycle of the inverter's work and stop does not meet the specified requirements, resulting in excessive load of the inverter, and the working cycle needs to be reset to increase the rest time of the inverter; F0011 indicates that the motor works at low speed for a long time, resulting in the inverter not working normally; F0041 indicates that the stator resistance of the motor is faulty, resulting in the inverter not working normally, and the stator resistance needs to be replaced; F0051 indicates that the storage device of the inverter has failed; F0052 indicates that the accommodating components of the inverter are damaged and need to be replaced.
