What should I do if the EGF alarm of Sanling E700 inverter?

The fault cause of the EGF alarm of Sanling E700 inverter may be the output side ground fault, overcurrent protection, when the inverter output (load.

side) This alarm appears when there is a ground fault and leakage current to ground.

The solution is to remove the three wires of the motor from the inverter, measure the resistance of the motor to the ground respectively to see whether there is a short circuit or leakage, and measure the u, v, w and ground resistance of the inverter when the inverter is not charged.

See if there is a short circuit or leakage.

EGF: Output-side ground fault, over-current protection.

This alarm occurs when a ground fault occurs at the inverter output (load side) and when there is a leakage current to ground.

After removing the three wires of the motor from the inverter, measure the resistance to the ground of the motor respectively to see if there is a short circuit or leakage.

In the case that the inverter is not charged, measure the u, v, w, and ground resistance of the inverter to see if there is a short circuit or leakage.

This phenomenon indicates that the output of the inverter is grounded and overcurrent protected! The possible reasons are: 1. The insulation of the motor deteriorates.

2. Poor wiring contact of the motor. 3. The cable connecting the motor is aging and the insulation is deteriorating. 4. Inverter monitoring circuit fault, false alarm.

You can disconnect the cable connected to the motor with no-load test and do an insulation test on the motor and cable! You can basically find the problem.

Check the circuit for problems.

Summary. Mitsubishi Inverter E700 Fault** is used to diagnose drive faults, and its meaning depends on the specific value of the fault**. Faults are usually made up of two or three digits, each with a specific meaning.

For example, a common fault** e700 might indicate a "communication failure within the drive". The specific meaning can be referred to the manual or technical manual of the inverter. When a drive fails, it is common to see the fault on the display** and the drive may also go into a state of shutdown.

In this case, the inverter should be inspected immediately and repaired according to the meaning of the fault. In summary, the Mitsubishi Inverter E700 Fault is used to diagnose the inverter fault, and the specific meaning can be referred to the inverter's instruction manual or technical manual. When the inverter fails, the inverter should be inspected immediately and repaired according to the meaning of the fault.

What is the fault of erhn.

I can't be sure if the "erhn" you mentioned is a valid glitch**. Fault is usually an abbreviation of a letter or number that is used to indicate a specific fault or problem. For example, "e700" is a common fault of Mitsubishi inverters**, which means "internal communication failure of the inverter".

If the "erhn" you are referring to is a valid fault**, then what it means may be related to the device model or brand. It is recommended that you consult the instruction manual or technical manual of the equipment to understand the specific meaning of the fault** "erhn". In conclusion, if the "erhn" you are referring to is a valid fault**, then what it means may be related to the device model or brand.

It is recommended that you consult the instruction manual or technical manual of the equipment to understand the specific meaning of the fault** "erhn".

Summary. E, FHN Mitsubishi inverter display is for critical failure, E-RHN: Motor overcurrent protection (motor overload cut-off) treatment method:

a lighten the load. (Most of them are caused by the stuck pump, fan or mechanism dragged by the motor) Please focus on checking the external mechanism. b. When the motor is constant torque, set the applicable motor as a constant torque motor.

c Correctly set the stall to prevent the operation.

What does Mitsubishi Inverter E700 Fault** mean? Mitsubishi inverter E700 is a fault that indicates that the speed deviation is too large, and the treatment method is: 1. Check whether the machinery is abnormal, whether the motor is parameter tuned, and whether the torque setting value F2-10 is small 2. Set the detection parameters reasonably according to the actual situation 3. Check whether the wiring between the inverter and the motor is disconnected.

E, FHNE, FHN Mitsubishi inverter display is for critical failure, E-RHN: Motor overcurrent protection (motor overload cut-off) treatment method: a lighten the load.

Hello dear! You are thinking about what it means to search for Mitsubishi inverter E700 failure**. Yes Answer:

Hello dear! The e700 is a series of high-performance inverters launched by Mitsubishi Electric with different solutions for different faults**. Here are some common faults** and how to deal with them:

1.E541: Capacitor Charging Error (Capacitance Insufficient or Exceeding Standard).

Solution: Confirm whether the input supply voltage, output load and speed are normal, and also check whether the capacitor is damaged, if the capacitor needs to be replaced. 2.

E542: Power module temperature rises. Solution:

Check and clean the vents and radiators inside and outside the drive to ensure that the heat is good and to prevent the power module from overheating. 3. e543：

The current is too high. Solution: Check whether the output cable and power supply line are connected correctly.
