[Example of how to adjustment the FM terminal frequency meter]
*Use the meter's adjustment screw to pre-adjust zero-point.
Key operated LED display Operation
–
Displays the operation frequency. (When standard monitor
display selection H is set to [operation frequency])
CWJ
The first basic parameter "CWJ" is displayed.
HO
Press either the △ key or the ▽ key to select "HO."
Press the ENTER key to confirm your choice. A value
corresponding to the setting of HOUN (FM/OUT terminal
functions selection) is displayed.
Press the △ key or the ▽ key to adjust the meter. The
meter reading will change at this time but be careful
because there will be no change in the inverter's digital LED
(monitor) indication.
⇔HO
The adjustment is complete. HO and the frequency are
displayed alternately.
The display returns to its original indications (displaying the
operation frequency). (When standard monitor display
selection H is set to [operation frequency].)
■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).
[Hint]
It's easier to make the
adjustment if you push and
hold for several seconds.
