  • When the TG300 inverter detects a fault, the fault is displayed on the digital operator and activates the fault contact output and the motor coasts to a stop.
  • Check the cause in the table below and take the corrective actions
  • To restart, turn ON the reset input signal or depress [>RESET] key or shut OFF the main circuit power supply once, to reset the stop status.
  • When a forward (S1) / reverse (S2) run command is input, the inverter does not receive a fault reset signal. Make sure to reset after turning OFF the S1 or S2 run command.
