Adjusting the meter in inverter stop state
• Adjustment of output current (=)
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.
When setting  to  for fixed output 1 (100% output current), a signal of absolute values will be
output (inverter's rated current = 100%). In this state, adjust the meter with the  (Meter adjustment)
parameter.
Similarly, if you set  to  for fixed output 2 (output current at 50%), a signal that is sent out when
half the inverter's rated current is flowing will be output through the FM terminal.
After meter adjustment is ended, set  to  (output current).
• Adjustment of other items (=,  to , )
If parameter  is set to : Fixed output 3 (Other than the output current: 100%), a signal that is
sent out when  is set to ,  to , (100%) will be output through the FM terminal.
100% standard value for each item is the following:

It's easier to make the adjustment if you
push and hold for several seconds.
