Error name Operation status at error occurrence
■Description
When an arc or helix is interpolated by the
designation of the center point, a difference
between a radius of start point-center point and a
radius of end point-center point exceeds the
parameter "Allowable circular interpolation error
width".
■Operation status at error occurrence
At start: The system will not operate.
During operation: The system will stop immediately.
■Description
• Positioning is carried out at a position beyond the
software stroke limit upper limit.
• The positioning address and new current value
exceed the software stroke limit upper limit.
• The sub point exceeds the software stroke limit
upper limit in the circular interpolation or helical
interpolation with sub point designation.
■Operation status at error occurrence
At operation start: The system will not operate.
At current value changing analysis: The current
value is not changed.
During operation:
• When the positioning address exceeds the
software stroke limit range and the control is
switched to the one for the out-of-range data
during a position control (including the position
control in speed-position switching control and
position-speed switching control), the system will
stop immediately.
• When the current feed value or machine feed
value during speed control (including speed-
position and position-speed switching control) or
manual control exceeds the software stroke limit
range, the system will stop with the setting
(deceleration stop only) of the detailed parameter
2 Sudden stop selection (stop group 3).

■Action
At operation start:
• Bring the current feed value into the software
stroke limit using the manual control operation.
( Page 479, CHAPTER 11)
• Correct the positioning address. (Also check
the arc address in the circular interpolation or
helical interpolation with sub point designation.)
Current value changing: Set the new current
value within the software stroke limit range. (

During operation: Correct the positioning address.
