Adjusting the meter in inverter stop state
Adjustment of output current (=1)
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 (output current 100% equivalent), 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 50% equivalent), 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).
Other adjustments ( = , - , , , )
= : When fixed output 3 (other than the output current) is set, a signal of the the value for
other monitors is fixed at the following values and output through the FM terminal.
100% standard value for each item is the following:
=0, 2, 12
=3, 4
=13
=18
