The frequency converter of stone engraving machine is used as the drive of the main shaft motor of the engraving machine, and it is also an essential key part. It has the function of protecting the main shaft, high efficiency and energy saving, and mainly makes it run smoothly, with small fluctuation and large torque at low speed.
The Cause Of The Inverter Failure:
1. Overload: It may be caused by short acceleration time, low voltage and heavy load.
2. Undervoltage: ER08 fault code appears in the inverter, indicating that the inverter is already in an undervoltage state. It may be a bad connection in the line, or it may be seriously overloaded.
3. Overcurrent: It may be the cause of the output short circuit of the inverter. It is necessary to check the circuit and the motor. If the inverter is still over-current after disconnecting it, it means that the inverter circuit of the inverter is damaged and needs to be repaired. If the damage is serious, it needs to be replaced.
4. The temperature is too high: ER11 fault indicates that the inverter is overheated. The main possible reasons are: the air duct is blocked, the cooling fan is damaged and cannot rotate, and the ambient temperature is too high.
