B-63944EN/02 PROGRAMMING 20.AXIS CONTROL FUNCTIONS
- 607 -
The stored stroke check function before move does not work in a
angular coordinate system. Unless this function is enabled, and the
coordinate system is converted to the Cartesian coordinate system, no
stroke check is made.
• Stroke limit external setting (function specific to the M series only
and valid only for OT1)
• Bit 7 (BFA) of parameter No. 1300 for specifying whether to issue
an alarm before or after a stroke limit is exceeded (valid for OT1
and OT3)
The stored stroke limit functions other than the above work in a
angular coordinate system.
- Relationships between this function and axis-by-axis input/output signals
The table below indicates the relationships between this function and
the meaning of each controlled axis signal.
The input/output signals are classified as signals valid for the program
coordinate system (Cartesian coordinate system) and signals valid for
the machine coordinate system (angular coordinate system). In the
"Classification" column, "Cartesian" is indicated for a signal that is
valid for the Cartesian coordinate system, and "Angular" is indicated
for a signal that is valid for the angular coordinate system.
A signal valid for the Cartesian coordinate system means a signal
valid for a specified axis, and a signal valid for the angular coordinate
system is a signal valid for actual machine movement.
This means that when a movement is made along the perpendicular
axis by a movement along the angular axis alone:
A signal valid for the Cartesian coordinate system is affected by
a movement along the angular axis.
A signal valid for the angular coordinate system is not affected
by a movement along the angular axis.
Input signal
Signal name Address Classification Remarks
Interlock for each axis *ITx G130 Cartesian
When a movement is made along the angular axis
only, interlocking the perpendicular axis does not
interlock a movement along the perpendicular axis
made by a movement along the angular axis.
Caution) When using the interlock signal for each
axis, make both of the angular axis and
perpendicular axis high.
Overtravel

Angular
This signal is applied to each axis independently.
(If the perpendicular axis is made high, no alarm is
issued for the perpendicular axis even when an OT
alarm is issued for the angular axis.)

*DECx X009 Angular This signal is applied to each axis independently.
Servo-off signal SVFx G126 Angular This signal is applied to each axis independently.
Control axis detach signal DTCHx G124 Angular This signal is applied to each axis independently.

Cartesian
A movement is made in the Cartesian coordinate
system. (When the +J/-J signal for the angular
axis is made high, a movement is made also along
the perpendicular axis.)
