4-axis linear interpolation control
In "4-axis linear interpolation control" ("[Da.2] Control method" = ABS linear 4, INC linear 4), four motors are used to carry out
position control in a linear path while carrying out interpolation for the axis directions set in each axis. (Refer to
Interpolation control for details on interpolation control.)
4-axis linear interpolation control (ABS linear 4)
In the absolute system 4-axis linear interpolation control, the designated 4 axes are used. Linear interpolation positioning is
carried out from the current stop position (start point address) to the address (end point address) set in the "[Da.6] Positioning
address/movement amount".
■
Setting positioning data
When using 4-axis linear interpolation control (ABS linear 4), set the following positioning data.
: Always set,
: Set as required,
: Setting restricted,
: Setting not required
*1
Refer to the following for information on the setting details.
• When the "reference axis speed" is set during 4-axis linear interpolation control, set so the major axis side
becomes the reference axis. If the minor axis side is set as the reference axis, the major axis side speed
may exceed the "[Pr.8] Speed limit value".
• Refer to
Page 64 Interpolation control for the reference axis and interpolation axis combinations.
