Prolong deceleration time
properly.
Reduce load inertia or improve
inverter capacitance or add
braking unit.
Detect input power and clear
fault.
Detect input power voltage and
eliminate fault.
Install input reactor.
Check input power, eliminate
fault.
Seek support from vendor.
Prolong acc time.
Restart motor until it totally
Stop; Set F1.00 to 1or 2.
Reset V/F curve or torque
boost value.
Select inverter with right
capacitance.
Prolong deceleration time.
Connect external braking
resistance or braking unit.
Select inverter with right
capacitance.
Check load change and
eliminate it.
Check input power, eliminate
fault.
Reset V/F curve or torque
boost value.
Check input power, eliminate
fault.
Unreasonable F5.06 setting.
Adjust load or select inverter
with right capacitance.
If long-term low-speed
operation is needed, please
choose special motor for
inverter.
