The terminal function can be selected by
Pr.178 to Pr.184 (Input terminal function selection)
. (Refer to the FR-E800 Instruction Manual
(Function).)

*1
The terminal function can be selected by
Pr.190 to Pr.192 (Output terminal function selection)
. (Refer to the FR-E800 Instruction Manual
(Function).)
*2
The open collector transistor is ON (conductive) in LOW state. The transistor is OFF (not conductive) in HIGH state.
*3
Terminal FM is available for the FM type inverter. Terminal AM is available for the AM type inverter.
*4
Refer to the FR-E800 Instruction Manual (Function).

Used as the power supply for an external frequency setting
(speed setting) potentiometer.

Frequency setting
(voltage)
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).
For voltage input,
input resistance: 10±1
k
Ω
, maximum permissible
voltage: 20 VDC.
For current input,
input resistance: 245 ±5
Ω
, maximum permissible
current: 30 mA.
4
Frequency setting
(current)
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).

Relay output (fault
output)
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)
Contact capacity: 240

Open collector
RUN
Inverter running
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
or DC injection brake operation.
Permissible load: 24 VDC
(27 VDC at maximum),
0.1 A
(The voltage drop is 3.4 V
at maximum while the
signal is ON.)
Frequency
detection
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
preset detection frequency.
