2.6.2 Details on the control circuit terminals (Ethernet
model)
 Input signal
*1 The terminal function can be selected by Pr.178 or Pr.179 (Input terminal function selection). (Refer to the FR-E800 Instruction Manual
(Function).)

Forward rotation start
Turn ON the STF signal to start
forward rotation and turn it OFF to
stop.
When the STF and
STR signals are turned
ON simultaneously, the
stop command is
given.
Input resistance: 4.7 k Ω ,
voltage when contacts
are open: 21 to 27 VDC,
current when contacts are
short-circuited: 4 to 6
mADC

Reverse rotation start
Turn ON the STR signal to start
reverse rotation and turn it OFF to
stop.

Contact input
common (sink)
Common terminal for the contact input terminal (sink logic).

External transistor
common (source)
Connect this terminal to the power supply common terminal
of a transistor output (open collector output) device, such as
a programmable controller, in the source logic to avoid
malfunction by undesirable current.
24 VDC power supply
common Common terminal for the 24 VDC power supply (terminal
PC). Isolated from terminal 5.
PC
External transistor
common (sink)
Connect this terminal to the power supply common terminal
of a transistor output (open collector output) device, such as
a programmable controller, in the sink logic to avoid
malfunction by undesirable current.
Power supply voltage
range:
22 to 26.5 VDC,
permissible load current:
100 mA

Safety stop input
terminal common
Common terminal for safety stop input terminals
Contact input
common (source)
Common terminal for contact input terminal (source logic).
24 VDC power supply Can be used as a 24 VDC 0.1 A power supply.

power supply When connecting the frequency setting potentiometer at an
initial status, connect it to terminal 10.
5 VDC ±0.5 V,
permissible load current:

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
Pr.178 or Pr.179 (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).
