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 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.

*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.

calibrating the indicator
from the operation panel.

). 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.
