· 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.)
