Terminal connection diagram

Source Logic
*1 DC reactor (FR-HEL)
Remove the jumper for the
Main circuit terminal
01160 or less if a DC reactor
is connected. The DC reactor
Control circuit terminal
supplied with the 01800 or
more should be connected to
these terminals.
3-phase AC
power supply
To supply power to the
*2
control circuit separately,
remove the jumper across R1/
L11 and S1/L21.
Control input signals (No voltage input allowed)
Terminal functions vary with the
input terminal assignment set in
Pr. 178 to Pr. 189.
Multi-speed
selection
*3 JOG terminal can be used
as pulse train input
terminal. Use Pr. 291 to
select JOG/pulse.
Second function selection
*4 AU terminal
can be used
as PTC input
terminal.
Current input selection
Selection of automatic restart after
instantaneous power failure
Contact input common (sink*)
24V DC power supply/
max. 100mA load current
Contact input common (source*)
*(Common for external power supply transistor)
Frequency setting signal (analog)
Frequency setting
potentiometer
Ω
1/2W, 1k
*5 Terminal input specifications
can be changed by analog
input specifications switchover
(Pr. 73, Pr. 267).
Set the voltage/current input
switch in the OFF position to
select voltage input (0 to 5V/
Terminal 4
0 to 10V) and ON to select
current input (0/4 to 20mA).
It is recommended to use 2W1kΩ
*6
when the frequency setting signal is
changed frequently.

*8 Brake resistor (FR-ABR)
Remove the jumper across terminal PR-PX
when connecting a brake resistor.
(00023 to 00250)
Terminal PR is provided for the 00023 to
00620.
Install a thermal relay to prevent an overheat
and burnout of the brake resistor.
