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. If the operation frequen-
cy is selected
to
be monitored, the ratio of the
p d s e ~ h T(: ~ q u s l ~ ~ ~
output frequency at the FM terminal can be set
