End point setting
error
• The start point is equal to the end
point in circular interpolation or
helical interpolation with sub point
designation.
• The end point address is outside
the range of -2147483648 to
2147483647 in circular
interpolation or helical interpolation
with sub point designation or center
point designation.
At start: The system will not operate.
During operation:
The system stops
immediately.
527
Center point setting
error
One of the following settings is
configured in circular interpolation or
helical interpolation with center point
designation.
• Start point = Center point
• End point = Center point
• Center point address is outside the
range of –2147483648 to
2147483647.
At start: The system will not operate.
During operation:
The system stops
immediately.
530
Outside address
range
• In the speed-position switching
control and the position-speed
switching control, the setting value
of a positioning address is
negative.
• In the 1-axis linear control (ABS), 2-
to 4-axis linear interpolation control
(ABS), or helical interpolation
control (ABS), the setting value of a
positioning address is outside the
range of 0 to 359.99999 [degree].
At start: The system will not operate.
During operation:
The system stops
immediately 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.)
532
Simultaneous start
not possible
Among the axes to be started
simultaneously, there is an axis on
which an error other than this error
occurs.
533 Condition data error
• The condition setting values are not
set or outside the setting range.
• The condition operator setting
values are not set or outside the
setting range.
• The condition operator is a bit
operator, and the parameter 1 is 32
or more.
• An unusable condition operator is
set for the set condition.
• The conditional operator has been
[parameter 1 parameter 2] with
05H (P1
** P2).
• The value in 'address' is out of the
setting range when the condition
target is set to 'Buffer memory (1-
word/2-word)'. (1-word: 0 to 32767,
2-word: 0 to 32766)
The operation is terminated.
534
Special start
instruction error No applicable special start
instruction is present.
535
Circular interpolation
not possible
The circular interpolation or helical
interpolation is carried out for the
axis with the "degree" unit setting.
