It
is possible
to
calibmte the meter connected to the
FM
terminal using the parameter unit. The
calibration function is valid to both monitor functions selected by Pr.54.
0
At the terminal
FM,
pulses are output as illustrated
below.
However, by setting a proper value
for Pr.900, the indication
of
the meter connected
to
the
inverter can
be
calibrated
by
using the
parameter unit without connecting a variable resistor. (Reler
to
page 49.)
The
pulse-train
output
at
the
FM
terminal
is
used
to
display the monitor data on the digital counter.
At the full-scale value, explained in the item for
Pr.55,
1440Hz
is output.
