13. POSITIONING MODE
(2) Travel completion, rough match, in-position
(a) Travel completion
The following timing charts show the output timing relationships between the position command
generated in the servo amplifier and the travel completion (MEND). This timing can be changed using
parameter No. PA10 (in-position range). MEND turns ON in the servo-on status. MEND does not turn
ON during automatic operation.
POINT
If an alarm cause, etc. are removed and servo-on occurs after a stop is made by
servo-off, alarm occurrence or forced stop (EM1) ON during automatic
operation, travel completion (MEND), rough-match, (CPO) and in-position (INP)
are turned on. To resume operation, confirm the current position and the
selected point table No. and program No. for preventing unexpected operation.
