(a) Function
• This instruction is giving the positioning speed override instruction to XGB built-in positioning.
• The positioning speed override is executed at the axis designated as ax at the rising edge of the
input condition, and if the current position reaches the position set in n1 during operation, the
current operation speed is overridden to the speed set in n2.
• The positioning speed override instruction is available in the deceleration and acceleration
sections and if the positioning speed override is executed during deceleration or dwell, no error
code is issued, but the instruction is not executed either.
(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.
