Interpolation mode
error
• For starting, a composite speed is
designated in the reference axis
parameter "Interpolation speed
designation method" using the speed
interpolation control or
4-axis linear interpolation control.
• For starting, a reference axis speed is
designated in the reference axis
parameter "Interpolation speed
designation method" using the circular
interpolation control.
At start : The system does not
operate.
During operation : The system stops with the
setting (deceleration
stop/rapid stop) of the
detailed parameter 2 rapid
stop selection
(stop group 3).
(Note that the deceleration
stop only occurs during the
manual pulse generator
operation.)
524
Control method setting
error
• The control method setting value is
outside the setting range.
• The number of control axes or the axis to
be interpolated differs from the previous
data when continuous positioning control
or continuous path control is to be
exercised for continuously.
• The NOP instruction was set to the
control method of positioning data No.
600.
525 Sub point setting error
Either of the following applies in the circular
interpolation with sub points designated.
• Start point = sub point
• End point = sub point
• Start point, end point, and sub point are in
line with each other.
• Sub point address and center point
address are outside the range of
–2147483648 to 2147483647.
At start : The system does not
operate.
During operation : The system stops
immediately.
526 End point setting error
• Start point is equal to end point in the
circular interpolation with sub points
designated.
• End point address is outside the range of
–2147483648 to 2147483647 in the
circular interpolation with auxiliary point
designation and center point designation.
527
Center point setting
error
Circular interpolation with center point
designation applicable to one of the
followings.
• Start point = Center point
• End point = Center point
• Center point address is outside the range
of –2147483648 to 2147483647.
