Error name
The command speed is outside the
setting range.
Linear interpolation, circular
interpolation, helical interpolation:
Reference axis is outside the
setting range.
Speed control interpolation:
Either of reference axis and
interpolation axis is outside the
speed range.
• In the interpolation control of the
speed control, 4-axis linear
interpolation control, or 4-axis
fixed-feed control, the system is
started while a composite speed is
set in "Interpolation speed
designation method" of the
parameter or positioning data of the
reference axis.
• In the circular interpolation control
or helical interpolation control, the
system is started while a reference
axis speed is set in "Interpolation
speed designation method" of the
parameter or positioning data of the
reference axis.
• The control system setting value is
outside the specified limit.
• The number of control axes or the
axis to be interpolated differs from
the previous data when the
operation is continuously
performed by setting the
continuous positioning control or
continuous path control.
• Machine OPR, fast OPR, or speed-
position or position-speed switching
control was performed in the
wiring-less mode.
• The NOP instruction was set to the
control system of positioning data
No. 600.
• Any value other than 0 was set at
buffer memory address 1906 (use
prohibited area).
One of the following settings is
configured in circular interpolation or
helical interpolation with sub point
designation.
• 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.

occurs during the manual pulse
generator operation.)

Operation status at error occurrence
The system stops with the
setting (deceleration
stop/sudden stop) of the
detail parameter 2 Sudden
stop selection
(stop group 3).
The system stops
immediately.
