The time of overload running is
too long.
SI external fault input terminals

 Communication address is wrong.
There is strong interference to
the communication.
The connection of the control
board is not good
Hall components is broken
The modifying

The motor capacity does not
comply with VFD capability
The rated parameter of the motor
does not set correctly.
The offset between
parameters from autotune and
the standard parameter is huge
Autotune overtime
Error of controlling the write and
read of the parameters
Damage to EEPROM
