Motor overload early warning -- (OL)
(Function code data = 7)
This output signal is used to issue a motor overload early warning that enables you to take an
corrective action before the inverter detects a motor overload alarm 0l1 and shuts down its
output.
This signal comes ON when the current exceeds the level specified by E34 (Overload early
warning).
Function code E34 is effective for not only the (OL) signal, but also for the "Current
detected" signal (ID).
Inverter ready to run -- (RDY)
(Function code data = 10)
This output signal comes ON when the inverter becomes ready to run by completing hardware
preparation (such as initial charging of DC link bus capacitors and initialization of the control
circuit) and no protective functions are activated.
Select AX terminal function -- (AX)
(Function code data = 15)
In response to a run command (FWD), this output signal controls the magnetic contactor on the
commercial-power supply side. It comes ON when the inverter receives a run command and it
goes OFF after the motor decelerates to stop because of a stop command received.
This signal immediately goes OFF upon receipt of a coast-to-stop command or when an alarm
occurs.
