Terminal connection diagram
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.

*7  Brake resistor (FR-ABR, MRS, MYS type) 
Install a thermal relay to prevent an 
overheat and burnout of the brake resistor. 
(The brake resistor can not be connected 
to the 0.1K and 0.2K.)
*6  A brake transistor is not built-in to the 0.1K 
and 0.2K.

*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.184 (input terminal function selection) 
to assign the function, and turn ON AU signal.

Ω 
when the frequency setting signal 
is changed frequently. 
*9  Operation and parameter setting can be 
done from the parameter unit (FR-PU07) 
and the enclosure surface operation panel 
(FR-PA07).  
(Use the option cable (FR-CB2     ).)  
RS-485 communication can be utilized from 
a personal computer and other devices.
*8  It is not necessary when calibrating the 
indicator from the operation panel.
*10  A personal computer and an inverter can be 
connected with a USB (Ver1.1) cable.
