YASKAWA drives the alarm without R91, should be A910. Both A910 and A710 and A720 are overload alarm, in which A710 is instantaneous overload alarm, and A720 is continuous overload alarm. The cause of the alarm: the power line fault phase error; servo drive; motor power does not match the mechanical part; locked; solution: confirm the power wiring is correct; confirm the normal drive; confirm the mechanical parts without the locking; to study the load condition, the calculation of the motor power.
