2.Error Signal Check And Solutions
2.1.Error message『LE1』 ：The voltage is too low during exercising, please check the input
AC power source, AC power source voltage shall between 110 / 220 V ± 10%.
2.2.Error message『OC』 ：The inverter output current overload(over 17.6A), replace inverter
if after reset power then start again still show『OC』. Replace the running belt or
deck if always happen while running.
2.3.Error message『OE』 ：The operation voltage too high, maybe happen at high incline level
and heavy load exercising, contact manufacture for solution.
2.4.Error message『PrEr』 ：The inverter Flash memory problem, replace the inverter.
2.5.Error message『EEr』 ：The inverter EEPROM problem, replace the inverter.
2.6.Error message『LE』 ：The voltage is too low when in idle or setting mode, please check
the input AC power source. The input AC power source under 110V(220V system) / 65V(110V
system) will show『LE』.
2.7.Error message『9F』 ：Output power U-V-W inequality, check motor wire connect to inverter
certainly or replace motor.
