Restrictions
(1) An error "Continuous path control not possible" (error code: 516) will occur and
the operation cannot start if "continuous path control" is set in " Da.1
Operation pattern". ("Continuous path control" cannot be set in fixed-
dimension feed control.)
(2) "Fixed-dimension feed" cannot be set in " Da.2 Control method" in the
positioning data when "continuous path control" has been set in " Da.1
Operation pattern" of the immediately prior positioning data. (For example, if
the operation pattern of positioning data No. 1 is "continuous path control",
fixed-dimension feed control cannot be set in positioning data No. 2.) An error
"Continuous path control not possible" (error code: 516) will occur and the
machine will carry out a deceleration stop if this type of setting is carried out.
(3) When the absolute position restoration mode is the "infinite length mode", an
error "control method setting error" (error code: 524) occurs, disabling a start.
Positioning data setting example
The following table shows setting examples when "1-axis fixed-dimension feed
control (fixed-dimension feed 1)" is set in positioning data No. 1 of axis 1.
Setting example
Positioning Set "Positioning complete" assuming the next positioning data will not
complete be executed.
Fixed-dimension
Set 1-axis fixed-dimension feed control.
feed 1
Designate the value set in " Pr.26 Acceleration time 1" as the
1
acceleration time at start.
Designate the value set in " Pr.9 Deceleration time 0" as the
0
deceleration time at deceleration.
Set the positioning address. (Assuming "mm" is set in " Pr.1 Unit
8 0 0 0 0 . 0 µ m
setting".)
– Setting not required (setting value will be ignored).
6000.00mm/min Set the speed during movement to the positioning address.
Set the time the machine dwells after the positioning stop (position
500ms
command output stop) to the output of the positioning complete signal.
Set this when other auxiliary operation commands are issued in
10
combination with the No. 1 positioning data.
