*1 Set Pr. 73, Pr. 267, and a voltage/current input switch correctly, then input an analog signal in accordance with the setting.
Applying a voltage signal with voltage/current input switch on (current input is selected) or a current signal with switch off (voltage input is
selected) could cause component damage of the inverter or analog circuit of signal output devices.
*2 Refer to chapter 4 of the instruction manual (applied).
Description
When connecting the frequency setting potentiometer at an initial
status, connect it to terminal 10.
Change the input specifications of terminal 2 when connecting it
to terminal 10E. (Refer to Pr. 73 Analog input selection in chapter 4 of
the instruction manual (applied).)
Inputting 0 to 5VDC (or 0 to 10V, 0 to 20mA) provides the
maximum output frequency at 5V (10V, 20mA) and makes input
and output proportional. Use Pr. 73 to switch from among input 0
to 5VDC (initial setting), 0 to 10VDC, and 0 to 20mA.
Set the voltage/current input switch in the ON position to select
current input (0 to 20mA).
*1
Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the
maximum output frequency at 20mA 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 OFF position to select
voltage input (0 to 5V/0 to 10V).
(Refer to chapter 4 of the instruction manual (applied).) Use Pr.
858 to switch terminal functions.
Inputting 0 to ±5 VDC or 0 to ±10VDC adds this signal to terminal
2 or 4 frequency setting signal. Use Pr. 73 to switch between the
input 0 to ±5VDC and 0 to ±10VDC (initial setting).
Use Pr. 868 to switch terminal functions.
Common terminal for frequency setting signal (terminal 2, 1 or 4)
and analog output terminal AM. Do not earth (ground).
