Basic Information
Interpolation Feed Rate
264
Changing Speed with the Program
The feed rate from the motion program can be added to the override that
changes the axes feed rate from the ladder program in order to conduct high
speed positioning.
The actual speed is calculated as follows:
Actual speed = Axes feed rate × (Axes override + Internal override)
Commands that can be specified by adding override from the motion program
are listed in the following table.

• The range of numerical values for axes override will not change even if
the internal override is added.
• The range of numerical values is 0.00% to 327.67%.
• The axes override value is valid only when the axes override enable re-
lay is ON. When it is OFF, the value is 100%.
• If the entered value is not within the stated range, the following values
will be assigned.
Negative values: 0%
Values exceeding 327.67%: 327.67%

Interpolation Feed Rate
The feed rate for the axis movement commands MOVEL, MOVEC, and
MOVETRAV can be set in the Operand F in motion programs. Overwriting the
value in F can change the feed rate though it is not valid during operations.
During motion program execution, the previously specified interpolation speed
will be held until the newly set speed is enabled. (Modal data.)
Upper Limit of Command Value
The value set in the parameter [P00M01: Maximum interpolation feed rate]
limits the speed after override, the speed specified in the operand F.
