11.3 Inching operation
11.3.1 Outline of inching operation
Important
When the inching operation is carried out near the upper or lower limit, use the
hardware stroke limit function (Refer to Section 12.4.4).
If the hardware stroke limit function is not used, the workpiece may exceed the
movement range, and an accident may result.
Inching operation
In inching operation, pulses are input to the drive unit at 1.8ms to move the
workpiece by a designated movement amount after the forward run JOG start
signal [Y8, YA, YC, YE] or reverse JOG start signal [Y9, YB, YD, YF] is turned ON.
The following shows the example of inching operation.
1)
When the start signal is turned ON, inching operation is carried out in the direction
designated by the start signal. In this case, BUSY signal is turned from OFF to ON.
2)
The workpiece is moved by a movement amount set in "
Cd.16
Inching movement
amount".
3)
The workpiece movement stops when the speed becomes "0". In this case, BUSY signal
is turned from ON to OFF. The positioning complete signal is turned from OFF to ON.
4)
The positioning complete signal is turned from ON to OFF after a time set in
"
