Terminal 10 and terminal 2
are used as PTC input
terminal (Pr. 561).
*4 It is recommended to
use 2W1kΩ when the
frequency setting signal
is changed frequently.
*5 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.

NOTE
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 output of the single-phase power input model is three-phase 200V.
