3.2.4 Interpolation Feed Speed Ratio Setting (IFP) Command
! Outline
The Interpolation Feed Speed Ratio Setting (IFP) command can set the interpolation feed
speed by designating the percentage of the Maximum Interpolation Feed Speed (FMX).
! Detailed Explanation
The IFP command method is shown as follows:
According to the above command, the value multiplied by the percentage which is
designated by the Maximum Interpolation Feed Speed (FMX) is set as the
interpolation feed speed.
• The IFP command cannot be used within the same block as the Interpolation
command.
• When designating an interpolation feed speed with the IFP command (instead of
using the F command), designate the Maximum Interpolation Feed Speed with the
FMX command first.
• When the IFP command is sent after the F command designation, the interpolation
feed speed set with the F command is canceled.
• The speed set by the IFP command is valid until being reset by the next IFP or F
command.
• A designating range of the IFP command is as indicated below:
Important Point
In a motion program that uses interpolation commands, be sure to designate the FMX
command at the beginning of the program to set the maximum interpolation feed speed. If
the F and IFP commands are sent without designating the FMX, an error occurs.
