8.2.6 Linear Interpolation Control with 2 axes
After executed by positioning operation start command (
「
Indirect start
」
,
「
Synchronous start
」
), then executing
interpolation control from starting position to the goal position with interpolation axis set as the main axis and sub axis.
(1) Linear interpolation control with absolute coordinates (
「
Absolute, Linear Interpolation
」
)
(a) Execute linear interpolation from starting position to the goal position designated on positioning data. Positioning
control is on basis of the designated position from homing.
(b) The direction of movement depends on the starting position and the goal position for each axis.
■ Starting position < Goal position : Positioning operation in forward
■ Starting position > Goal position : Positioning operation in reverse

(c) Restrictions
Linear interpolation with 2 axes may not be executed in the case below.

「
Sub axis setting
」
Error (error code : 253)
▪
「
Sub axis setting
」
of main axis operating data is “Axis-undecided”
▪
「
Sub axis setting
」
of main axis operating data is the same as main axis no.
▪
「
Sub axis setting
」
of main axis operating data exceeds the settable axis No.
Note
Because more than 2 axes are in action, so need user to pay attention
(1) The commands available are as follows.
Speed override, Dec. time, Emergent stop, Skip operation, Continuous operation
(2) The commands unavailable in linear interpolation are as follows.
Position/Speed switching control, Position override
(3) The parameter items which work depending on the value of each axis are as follows.
Backlash compensation, Software Upper/Lower limit
