9.2.1 Control details

Cd.8
BUSY signal [X10 to X1F]
In the incremental feed operation, the constant feedrate set in "
feedrate" is output to the servo amplifier by setting "1" in "
start" or " Reverse rotation JOG start".
Cd.9
While the positioning start signal [Y10 toY1F] is ON, "forward rotation JOG start" and
"reverse rotation JOG start" for that axis are ignored regardless of positioning
executing.
Operation procedure for incremental feed operation is shown below.
1) When except "0" is set in "
Forward rotation JOG start" or "
is started by the specified direction and the acceleration time set in "
operation acceleration time". At this time, the BUSY signal [X10 to X1F] changes
from OFF to ON.
2) When the command reaches the speed set in "
continues at this speed.
3) A deceleration is started by the deceleration time set in "
deceleration time" so that the movement amount that moved after operation start
becomes the incremental feedrate.
4) The operation stops when the speed becomes "0". At this time, the BUSY signal
[X10 to X1F] changes from ON to OFF.

POINT
• Incremental feed operation can be used without completing OPR.
• When both the forward rotation start and reverse rotation start are set
simultaneously, the "forward rotation start" is given priority. Reverse operation
cannot be executed after the forward incremental feed stop.
