Setting Of Linear Interpolation Axis - Mitsubishi Electric MELSEC Q Series User Manual

8 POSITIONING CONTROL

8.3.2 Setting of linear interpolation axis

Always set the basic parameter "
interpolation. The interpolated axis can be set to "interpolation group". Set the same
value to "interpolation group" of interpolated axes. Up to 4 axes can be set to one
group, and up to 4 groups can be set.
The interpolation control can be executed for the axes that set the same value to the
interpolation group. When the "ABS linear interpolation" or "INC linear interpolation" is
set in " Control system" of reference axis, and the positioning start signal [Y10 to
Da.1
Y1F] is turned ON, the all axes of same interpolation group can be started to execute
the interpolation control.
The data of reference axis are used in the following positioning data. (The value set in
the positioning data of the interpolation axis is ignored.)
• " Operation pattern"
Da.0
• " Control system"
Da.1
• " Acceleration time"
Da.2
• " Deceleration time"
Da.3
• " Command speed"
Da.4
• " Dwell time",
Da.8
Set only " Positioning address/movement amount" for the all axes of the same
Da.6
group for the interpolation control.
POINT
(1) Always set the basic parameter "
interpolation. When "0" is set to interpolation group, an "error code 1040" will
occur.
(2) The interpolation group becomes valid by input from the buffer memory at the
PLC READY ON.
(3) Do not turn ON the positioning start signal [Y10 to Y1F] of the interpolation axis
except reference axis at the interpolation control start. An error may occur at
the start.
(4) The linear interpolation can be started for the axes that set the same value to
the interpolation group. A part of the axes cannot be started among those
axes.
(5) A single axis can be started by setting the "ABS linear interpolation" or "INC
linear interpolation" in "
