Analog Output Settings Analog output 1 is used in this example. It is set to a range of 4 to 20 mA. The
scaled value is set in the analog conversion area of the Analog Output Unit.
Refer to the first line in the programming example in Referencing the Automat-
ically Calculated Inverter Frequency Command Value on page 334 for a timer
for the time required for the Analog Output Unit’s data to be valid (analog con-
version trigger: T0).
Address Usage
D1010 Holds the frequency command value converted for the analog
output resolution.
D1011
D1020 Holds the frequency command value converted from 0.01-Hz
increments to hertz.
T0 Analog conversion trigger
Address Usage
D102 Bits 00 to 15: Analog output value
CIO 100.02 Forward (external output)
CIO 100.03 Reverse (external output)
Analog output 1 set to a
range of 0 to 20 mA
(range code: B hex).
Analog outputs 2 to 4 are
not used.
D103 (scaled value) is
initialized.
The scaled value in
D102 is written as the
converted data for
analog output 1.
