Function	Code	Function	Action
No.
0	LL	Frequency lower limit	ON: The output frequency is above the NN set
			value.
			OFF: The output frequency is equal to or less than
			the NN set value.
1	LLN	Inversion of frequency lower limit	Inversion of LL setting
2	UL	Frequency upper limit	ON: Output frequency is equal to or higher than
			WN value.
			OFF: Output frequency is lower than WN value.
3	ULN	Inversion of frequency upper limit	Inversion of UL setting
4	LOW	Low-speed detection signal	ON: Output frequency is equal to or higher than
			H value.
			OFF: Output frequency is lower than H
			value.
5	LOWN	Inversion of low-speed detection signal	Inversion of LOW setting
6	RCH	Designated frequency attainment signal	ON: The output frequency is equal to or less than
		(completion of acceleration/deceleration)	the specified frequency ± frequency set with
			H.
			OFF: The output frequency is above the specified
			frequency ± frequency set with H.
7	RCHN	Inversion of designated frequency attainment	Inversion of RCH setting
		signal (inversion of completion of
		acceleration/deceleration)
8	RCHF	Set frequency attainment signal	ON: The output frequency is equal to or less than
			the frequency set with H ± H.
			OFF: The output frequency is above the frequency
			set with H ± H.
9	RCHFN	Inversion of set frequency attainment signal	Inversion of RCHF setting
10	FL	Failure signal (trip output)	ON: When inverter is tripped
			OFF: When inverter is not tripped

12	OT	Over-torque detection	ON: Torque current is equal to or larger than
			H set value and longer than H
			set time.
			OFF: The torque current is equal to or less than
			(H set value - H set value).
13	OTN	Inversion of over-torque detection	Inversion of OT
14	RUN	Start/Stop	ON: When operation frequency is output or during
			(FD)

				11
			overload protection level
17	POLN	Inversion of OL pre-alarm	Inversion of POL setting
20	POT	Over-torque detection pre-alarm	ON: Torque current is equal to or larger than 70%
			of H set value.
			OFF: The torque current is below (H set
			value x 70% - H set value).
21	POTN	Inversion of over-torque detection pre-alarm	Inversion of POT setting
22	PAL	Pre-alarm	One of the following is turned on:
			ON POL, POT, MOFF, UC, OT, LL stop, COT,
