Terminal function description
Used as the power supply for an external frequency setting
(speed setting) potentiometer.
Inputting 0 to 5 VDC (or 0 to 10 VDC) provides the maximum
output frequency at 5 V (or 10 V) and makes input and
output proportional. Use Pr.73 to switch among input 0 to 5
VDC (initial setting), 0 to 10 VDC, and 0 to 20 mA.
* The initial setting varies depending on the specification.
Set the voltage/current input switch to the "I" position to
select current input (0 to 20 mA).
Inputting 4 to 20 mADC (or 0 to 5 VDC, 0 to 10 VDC)
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 (current input at initial setting), assign "4"
to Pr.178 or Pr.189 (Input terminal function selection) before
turning ON the AU signal.
* The initial setting varies depending on the specification.
Use Pr.267 to switch among input 4 to 20 mA (initial setting),
0 to 5 VDC, and 0 to 10 VDC. Set the voltage/current input
switch to the "V" position to select voltage input (0 to 5 V / 0
to 10 V).
Common terminal for the frequency setting signal (terminal
2 or 4). Do not earth (ground).
Terminal function description
1 changeover contact output that indicates that an inverter's
protective function has been activated and the outputs are
stopped.
Fault: discontinuity across B and C (continuity across A and
C), Normal: continuity across B and C (discontinuity across
A and C)
