short circuit to PG ground or not
Assure driver output wire no short
circuit, assure motor no damage
Abnormal wiring of motor
Check motor wiring order
Adjust motor wiring sequence

Solution
Load is too heavy
Check actual load if the value of
parameter exceed maximum or not
Decrease load, adjust limit parameter
Oscillation of
machine
Check the machine if oscillation exists
or not
Modify the parameter of control loop;
enlarge acceleration/deceleration time
wiring error of
