13 If all function are normal and no error
signal after reset power, it maybe cause
by power core, maybe power core connect not
well, please check the power core.
If all function are normal and no error
signal after reset power, maybe the
loading is too heavy and inverter to start
the over current protect mode. If loading
is too heavy the motor noise will more
louder over 12km/h and running belt speed
will decreased or slippery while loading.
Please maintenance or replace the running
belt and running deck.
