The inability of the frequency converter to move the load may be caused by power quality issues, improper parameter settings of the frequency converter, motor faults, excessive load, or control circuit problems.

Power quality issues

The quality and stability of the power supply play a crucial role in the normal operation of the motor and the control of the frequency converter. If the quality of the power supply voltage is poor, the voltage fluctuation amplitude is large, the noise is too high or too low, it will affect the control accuracy of the frequency converter and cause the frequency converter to not start.

Improper setting of frequency converter parameters

Before using the frequency converter, it is necessary to set the operating parameters of the frequency converter according to the parameters of the motor. If the motor parameters are set incorrectly or the frequency setting value is selected incorrectly, it will cause the motor to fail to start when loaded.

Motor failure

If the motor itself has a fault, it will not work when loaded. For example, problems such as coil damage, motor bearing damage, and uneven weight of components can cause the motor to be unable to withstand the load and start.

Excessive load

If the load is too large and exceeds the bearing capacity of the motor itself, it will cause the frequency converter to fail to start. So when users choose motors and frequency converters, they need to consider the size of the load and select motors and frequency converters that can withstand the load.

Control circuit issues

When there is a control circuit problem, it can also cause the frequency converter to fail to start. For example, when using electromagnetic relays or time relays, if the previous control function does not return to the end value, it will cause the control circuit to be incomplete, resulting in the inverter being unable to start.

In summary, when facing the problem of "the frequency converter cannot move the load", the above aspects can be investigated and solved.
