Chapter 5 Function Code
îš„ Assignment of Momentary power failure decelerating IPF2 (Function code data = 79)
When F14 is 2 or 3, the DC medium voltage decreases to H15 "Continuous running level" or lower, and the
signal turns on when the conditions turns to continuous running level. After restoration of power, when the
DC medium voltage increases to "set voltage of H15 + 10 V or higher," the signal turns off. Even when F14 is
4 or 5, the signal turns on when the DC medium voltage decreases to the undervoltage detected level or
lower, the signal turns on. The signal turns off when the voltage becomes "Undervoltage level + 10 V or
higher." (

Function code F14, H15)
îš„ Assignment of positioning completion signal PSET (Function code data = 82)
This output signal comes on as a positioning completion signal. (

Function code J97 to J99)
îš„ Assignment of maintenance timer MNT (Function code data = 84)
This function outputs an ON signal when the cumulative run time of the motor 1 exceeds the preset time or
when the startup time of the motor 1 exceeds the preset count.

Function code H78, H79)
îš„ Assignment of alarm details signals AL1, AL2, AL4, and AL8 (Function code data = 90, 91, 92, 93)
This function outputs the operation status of the inverter protection function.
