GD series inverter is used in driving large inertia load, such as centrifuge, sanding machine, fan and so on. The load is consistent with the rated parameters of the inverter, that is, some OV or OC faults will be reported during deceleration. If you encounter these elements: speed mode, large inertia and deceleration alarm failure, then try to change P04.09 to 0, which can basically solve most of the problems.
