Sequential run (using sequential run start signal)
Set Pr50 – 53,70,71 as follows, and assign the function of signal input.
Of signal inputs 1 – 4,5,7 (
I
1 –
I
6), set the input parameter used for run start at “9” (sequential run start).
Positioning point number is incremented by one whenever the sequential run start signal is turned on. (When homing is
completed, the initial run start point is always the 1st point.)
The maximum of run point can be set by Pr22.
e.g.) When Pr22 is 3, the motor runs in the order: the 1st point
the 2nd point
the 3rd point
the 1st point
・・・
whenever run command is input.

Start signal (input)
(1) Choose a point number for point designation run. Point designation is not required (made ineffective) in sequential
operation.
(2) Set the run start signal at “ON” (Default setting: ON when shorted to GND).
It activates operation.
(3) Make sure that in-motion signal (BUSY) is on, and then return the run start signal to off. (Assign the function of in-
motion signal to signal output 01 or 02 by Pr5E and 5F.) Alternatively, turn on the run start signal, and turn it off in
20msec. Changing the next point designation number for positioning operation at this point causes no problem.
(4) When positioning operation is completed, in-motion signal (BUSY) returns to off. (If the run start signal is not off, posi-
tioning when operation is completed, in-motion signal still remains on.) In-position signal, after completion of com-
mand output, turns on when position error (difference between command position and actually reached position) is
below setting of Pr38.

Operation instruction can be given to the motor only when in-motion signal is off.
