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.
Description
Used as power supply when connecting potentiometer
for frequency setting (speed setting) from outside of
the inverter.
(
Refer to the chapter 4 of the Instruction Manual
(applied))
Inputting 0 to 5VDC (or 0 to 10V) provides the
maximum output frequency at 5V (10V) and makes
input and output proportional. Use Pr. 73 to switch
between input 0 to 5VDC input (initial setting) and 0 to
10VDC.
Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides
the maximum output frequency at 20mA and makes
input and output proportional. This input signal is valid
only when the AU signal is ON (terminal 2 input is
invalid). Use Pr. 267 to switch from among input 4 to
20mA (initial setting), 0 to 5VDC and 0 to 10VDC. Set
the voltage/current input switch in the "V" position to
select voltage input (0 to 5V/0 to 10V).
