modules are equipped
SLOT : Setting up the numbers of slots where modules
are equipped
AXIS : Specifying the axis to give commands
1 ~ 4: 1axis ~ 4axis
STEP : Step No. to operate

DONE : Keeping 1 after the initial operation
STAT : Outputting error No. that occurred during
executing function blocks
(1)
The command for
ellipse interpolation
is sent to the axis specified as AXIS of the embedded positioning.
(2) For the specified step of STEP in the specified axis, the ellipse interpolation is performed at the angle set in DEG in the
ratio set in RATIO.
(3) The ellipse interpolation distorts the operating data of the step that is set as circular interpolation in the ratio of ellipse
ratio(RATIO) and performs ellipse operation at the operating angle set in DEG. Therefore, the step of the operating data set
in STEP should be set up based on circular interpolation control.
(4) The ellipse ratio can be set in the range of 1 ~ 65535 and its unit is [X10
-2
%]. Namely, if the value is set as 65535, you
will get 655.35%.
(5) The operating angle can be set in the range of 1 ~ 65535 and its unit is [X10
-1
degree]. Namely, if the value is set as
3650, you will get 365.0 degree.
(6) In AXIS, you can set up the axis to command and select one among 1~4. If the values other than set ones are selected,
“error 6” will occur.
