9 MAIN POSITIONING CONTROL
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) If the movement amount of each axis exceeds "1073741824 (=2
30
)" at the
setting of "0: Composite speed" in "
Pr.21
Interpolation speed designation
method", an error "outside linear movement amount range" (error code: 504)
will occur at a positioning start and positioning cannot be started. (The
maximum movement amount that can be set in "
Da.5
Positioning
address/movement amount" is "1073741824 (=2
30
)".
(3) "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.
(4) When the absolute position restoration mode is the "infinite length mode", an
error "control method setting error" (error code: 524) occurs, disabling a start.
