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 the terminal 4 (current input at initial setting), assign
"4" to any parameter from Pr.178 to Pr.184 (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)
The output is in LOW state when the inverter output
frequency is equal to or higher than the starting frequency
(initial value: 0.5 Hz). The output is in HIGH state during stop
*2
or DC injection brake operation.
The output is in LOW state when the inverter output
frequency is equal to or higher than the preset detection
frequency, and is in HIGH state when it is less than the
*2
preset detection frequency.
Common terminal for terminals RUN and FU.
Among several monitor items such as
output frequency, select one to output it
via these terminals. (The signal is not
output during an inverter reset.)
The size of output signal is proportional to
the magnitude of the corresponding
monitor item.
