Brake unit
(Option)
*8 Brake resistor (FR-ABR)
Install a thermal relay to prevent an overheat
and burnout of the brake resistor.
(The brake resistor can not be connected to
the FR-D720S-008SC and 014SC.)
*5 Terminal input specifications can be changed by analog input
specifications switchover (Pr. 267) (initial settings in frame).
Set the voltage/current input switch in the "V" position to
select voltage input (0–5 V/0–10 V) and "I" (initial value) to
select current input (0/4–20 mA.)
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.
