When driving three or more motors, use the plug-in option (FR-A7AR).

Always provide mechanical interlocks for the MC.
(3) I/O signals
· Turn the X14 signal on when performing advanced PID control. Set "14" in
Pr. 186 to Pr. 189 (input terminal
function selection)
to assign a function to the X14 signal.
· PID control depends on the
Pr. 127 to Pr. 134, C42 to C45
settings.
(Refer to page 219)
· Use
Pr.190 to Pr.196 (output terminal function selection)
or relay output option (FR-A7AR) to assign functions of motor
control signal to
Pr.320 to Pr.322 (RA1, RA2, RA3 output selection)
. (Only positive logic is available for output terminals.)
