Terminal connection diagram
Main circuit terminal
Control circuit terminal
*1 Remove the jumper
across the terminals P1
and P/+ to install
Control input signals (No voltage input allowed)
The function of these
terminals can be
changed to the reset
signal, etc. with the input
(Pr. 178 to Pr. 182)
*3 When using terminals PC-
SD as a 24VDC power
supply, take care not to
short across terminals
PC and SD.
(Common for external power supply transistor)
Frequency setting signals (Analog)
*4 Terminal input specifications
can be changed by analog
switchover (Pr. 73).
Terminal 10 and terminal 2
are used as PTC input
terminal (Pr. 561).
*5 It is recommended to
use 2W1kΩ when the
frequency setting signal
is changed frequently.
*6 Terminal input specifications can be changed by analog
input specifications switchover (Pr. 267). Set the
voltage/current input switch in the "V" position to select
voltage input (0 to 5V/0 to10V) and "I" (initial value) to
select current input (4 to 20mA).
To use terminal 4 (initial setting is current input), set "4"
in any of Pr.178 to Pr.182 (input terminal function
selection) to assign the function, and turn ON AU signal.
To prevent a malfunction caused by noise, separate the signal cables more than 10cm from the power cables. Also
separate the main circuit wire of the input side and the output side.
After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes
in an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.
The terminals S1, S2, SC, and SO are for manufacturer setting. Do not remove the shortening wires across the
terminals S1 and SC and the terminals S2 and SC.
Contact input common
24VDC power supply
. DC reactor (FR-HEL)
When connecting a DC reactor, remove the
jumper across P1 and P/+.
2 0 to 5VDC
(0 to 10VDC)
4 4 to 20mADC
0 to 5VDC
0 to 10VDC
*7 Brake resistor (FR-ABR, MRS type, MYS type)
Install a thermal relay to prevent an overheat
and burnout of the brake resistor.
Always install a thermal relay when using a
brake resistor whose capacity is 11K or higher.
Terminal functions vary
by Pr. 192 A,B,C terminal
Open collector output
Terminal functions vary by
Pr. 190 RUN terminal function
Open collector output common
(Frequency meter, etc.)
*8 It is not necessary when
calibrating the indicator
from the operation panel.
