NOTE Set Pr. 267 and a voltage/current input switch correctly, then input analog signals in accordance
with the settings.
Applying a voltage with voltage/current input switch in "I" position (current input is selected) or a
current with switch in "V" position (voltage input is selected) could cause component damage of
the inverter or analog circuit of output devices. Refer to section 6.16 for details.

Description
Used as power supply when connecting potenti-
ometer for frequency setting (speed setting) from
outside of the inverter.
Rated output voltage: 5 V DC
Recommended potentiometer: 1 k , 2 W linear,
multi turn potentiometer
Inputting 0 to 5 V DC (or 0 to 10 V) provides the
maximum output frequency at 5 V (10 V) and
makes input and output proportional. Use Pr. 73
to switch from among input 0 to 5 V DC (initial
setting), 0 to 10 V DC.
Inputting 4 to 20 mA DC (or 0 to 5 V, 0 to 10 V)
provides the maximum output frequency at 20
mA and makes input and output proportional.
This input signal is valid only when the AU signal
is on (terminal 2 input is invalid).
To use terminal 4 (initial setting is current input),
set "4" to any of Pr. 178 to Pr. 184 (input terminal
function selection), and turn AU signal ON.
Use Pr. 267 to switch from among input 4 to
20 mA (initial setting), 0 to 5 V DC and 0 to
10 V DC. Set the voltage/current input switch in
the "V" position to select voltage input (0 to 5 V/0
to 10 V).

Terminal 5 provides the common reference
potential (0 V) for all analog set point values and
for the analog output signals AM (voltage). The
terminal is isolated from the digital circuit's refer-
ence potential (SD). This terminal should not be
grounded. If local regulations require grounding
of the reference potential note that this can prop-
agate any noise in the ground potential to the
control electronics, thus increasing sensitivity to
interference.
