2.1 Wiring
2.1.1 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 drive unit.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the drive unit clean. When drilling mounting
holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the drive unit.

*6 Brake resistor (FR-ABR, MRS type, MYS
type)
Install a thermal relay to prevent an
overheat and burnout of the brake resistor.
(The brake resistor cannot be connected
to the 0.2K.)
*7 It is not necessary when
calibrating the indicator
from the operation panel.

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.

*8 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.
