The new current address is outside the
ranges of 0 to 359.99999, where the
control unit is set to "degree".
• The control method sets an operation
pattern (continuous path control) using
new current positioning data.
• The operation pattern sets a "new current
value" in the control method using the
data following the "continuous path
control" positioning data.
• The continuous path control is designated
using a control method which is not
allowed to use for continuous path control
such as speed control, speed-position
switching control, position-speed
switching control, fixed-feed, and current
value changing.
• The previous data such as those on
speed control, speed-position switching
control, position-speed switching control,
fixed-feed, and current value changing
shows a continuous path control.
• The continuous positioning control is
designated for speed control or position-
speed switching control.
The operation pattern set value is 2.
Interpolation is started during the operation
of the interpolation axis.
The reference and interpolation axis units
are different at the parameter "interpolation
speed designation method" setting of
"composite speed".
In 2-axis interpolation, the axis to be
interpolated is the self axis or an axis not
present.
The command speed is outside the setting
range.
Linear interpolation, circular interpolation:
Reference axis is outside the setting
range.
Speed control interpolation:
Either of reference axis and interpolation
axis is outside the speed range.

Operation status at error occurrence
Current value is not changed.
The system does not operate at start.
At start : The system does not
operate.
During operation : The system stops with the
setting (deceleration
stop/sudden stop) of the
detailed parameter 2
Sudden stop selection
(stop group 3).
(Note that the deceleration
stop only occurs during the
manual pulse generator
operation.)
