■Adjustment scale with meter adjustment HO parameter

Connect meters as shown below.

<Frequency meter> Meter: frequency

Meter: ammeter

(HOUN: 1)

The reading of the frequency meter will fluctuate during scale adjustment.

☆Optional frequency meter: QS-60T

[Connected meter selection parameters]

☆Make the maximum ammeter scale at least 150 percent of the inverter's rated output current.

Title	Function		Adjustment range	Default setting
		-1 : Open collector output			5
		0	: Output frequency
		1	: Output current
	Meter selection	2	: Set frequency	0
HOUN		3 : For adjustment (current fixed at 100%)
		4	: For adjustment (current fixed at 50%)
		5	: For adjustment (output fixed at the max
			frequency)
		6	: For adjustment (gain display )

■Resolution

All FM terminals have a maximum of 1/256

[Example of how to adjustment the FM terminal frequency meter] * Use the meter's adjustment screw to pre-adjust zero-point.

■Adjusting the meter in inverter stop state

If, when adjusting the meter for output current, there are large fluctuations in data during adjustment, making adjustment difficult, the meter can be adjusted in inverter stop state.

If HOUN is set to  “for adjustment (current fixed at 100%)”, the inverter puts out signals via the FM / OUT terminal, assuming that 100% of current (inverter’s rated current) is flowing. In this state, adjust the meter with the HO (Meter adjustment) parameter. (HOUN: 4, 5, 6, 7 can be adjusted in the same way.)

After meter adjustment is ended, set HOUN to  (output current).
