Speed setting
(voltage)
Inputting 0 to 5VDC (or 0 to 10V) provides the
maximum rotation speed 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.
Input resistance 10k1k
Permissible maximum
voltage 20VDC

Speed setting
(current)
Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the
maximum rotation speed 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).
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 input
among 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).

NOTE
Under position control, some terminals have different functions. (Refer to page 90)
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 drive unit or analog circuit of output
devices. (Refer to page 168 for details)
