•
This signal turns ON for the time set in "
Pr. 7
Positioning complete signal output
time" from completion of position control of the corresponding axis.
(It does not turn ON if 0 is set in "
Pr. 7
Positioning complete signal output time".)
•
While ON, this signal turns OFF if a positioning control start (including OPR control)
or JOG operation start is made.
•
This signal does not turn ON at the termination of JOG operation.
•
This signal does not turn ON if position control is stopped midway.
Important
: "Position control complete" of the QD70 refers to the point when the pulse output from
QD70 is completed.
Thus, even if the QD70's positioning complete signal turns ON, the system may continue
operation.
