Load GD too large?
Did start-up occur during idle run?
Is motor being turned by other
force?
Excessive deceleration?
Braking frequency too high?
Feedback signal cable
disconnected?
Feedback signal correct?
Gain frequency correct?

Check points
Over-shoot or under-shoot
happened?
Communication cable
disconnected?
+24V power supply output from the
control circuit
shorted?
Missing an output phase?
Missing an input phase?
Short-circuited when grounding?
of Feedback signal cables are well
connected?
Is motor being driven by other
deviation force?
Cooling fan is working?
Turn off the power and wait until
the CHARGE lamp turns off, turn
the power on again and check the
alarm.
Prolong acceleration time
Decrease the setting value
Eliminate the abrupt change (increase)
Decrease the setting value
Prolong deceleration time
Decrease the setting value
Reduce the load
Increase the capacity of the inverter and motor
Flying start.
Redesign the system so that the motor is not
driven by external force.
Use a brake resistor with a larger capacity.
Prolong the deceleration time (so that GD
the load is met)
Reduce the braking frequency
Increase the brake resistor capacity
Check feedback signal cable and connect
securely.
Set gain frequency properly
（F1402, F1404）
Confirm speed command value or torque
command value
Confirm communication cables are connected
securely
Check the +24V output power supply for load
overloaded or conditions
Connect the output cables securely
Check and improve the input power
Confirm output cable and motor insulation
performance
Connect the feedback signal cable securely
Redesign the system so that the motor is not
driven by external force.
Check the fan performance
