FUNCTION C
ODES
„ 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.
„ Switch motor drive source between commercial power and inverter output
-- SW88 , SW52-2 and SW52-1 (Function code data = 11, 12, and 13)
Assigning these output signals to transistor output terminals [Y1], [Y2], [Y3] and [Y4]
enables the terminal command
ISW50 or ISW60 that controls the magnetic contactor for
switching the motor drive source between the commercial power and the inverter output
according to the integrated sequence.
Refer to E01 through E07 (data = 40 and 41).
„ 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 with a stop command received.
This signal immediately goes OFF upon receipt of a coast-to-stop command or when an alarm
occurs.
