AX Terminal Function (AX)
This function is used to control the electromagnetic contactor (MC) at the inverter input side in associ-
ation with the RUN command. It turns ON when the RUN command is input. When the stop command
is input, this function turns OFF after the inverter undergoes a deceleration stop. This function turns
OFF momentarily when the free run command is input and an alarm is generated. “AX” can be select-
ed at a capacity of 18.5kW or more of auxiliary power supply
.
Connect the power supply directly between R0 and T0.
