PID control
· Alternative system (Pr. 579 = "1"), direct system (Pr. 579 = "2"), alternative-direct system (Pr. 579 = "3")
*1 When driving three or more motors, use the plug-in option (FR-A7AR).
*2 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 261)
·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.)

selection), parameters for relay
output option (FR-A7AR).
