Chapter 5 Positioning Instructions
5 - 16
(a) Function
• This instruction is giving the straight interpolation starting instruction to XGB built-in positioning.
• The two axes of XGB positioning conduct straight interpolation starting at the rising edge of input
condition.
• If the instruction is executed, the two axes of XGB positioning carried out the straight interpolation
operation according to the axis setting designated in n2. The step number to be operated is the
step number set in n1.
• In setting of the axis of n2, the axis to carry out the straight interpolation operation as follows.
Bit number
axis Y axis X
- Each bit refers to the axis to start the straight interpolation. In the case of XGB built-in positioning,
n2 should be fixed as 3 since only axis X and axis Y are available. Otherwise, error code 253 is
issued and it does not operate.
(b) Error
• If the value designated as ax (instruction axis) is other than 0 and 1, the error flag (F110) is set
and the instruction is not executed.
• Since this case if an error of execution of the instruction, the error in positioning area K error
flag(axis X:K4201, axis Y: K4301) does not turn On..
• If the set value of the starting step number gets out of the settable range, instruction Error
Flag(F110) is not set, the error flag of positioning area K (axis X:K4201, axis Y: K4301) turns On,
and the operation does not occur.
