parameters identification;
3: Voltage is too low;
4: Sudden load added during
operation;
5: The model of inverter is too
small;
6: The braking resistor is short.
1: Input voltage is too high;
2: An external force drags the
motor during acceleration;
3: Acceleration time is too short;
4: No braking units or braking
resistors added
1: Input voltage is too high;
2: An external force drags the
motor during deceleration;
3: Deceleration time is too short;
4: No braking units or braking
resistors added
1: Input voltage is too high;
2: An external force drags the
motor during deceleration;

1: Eliminate the peripheral failure;
2: Initiate the identification of
motor parameters;
3: Adjust the voltage to the normal
range;
4: Choose rotational speed tracking
start or start it after the motor stops;
