Command Reference
8.1.7 Maximum Interpolation Feed Speed Setting (FMX)
(1) Overview
The Maximum Interpolation Feed Speed Setting command (FMX) sets the maximum feed speed for interpolation
related commands MVS, MCW, MCC, and SKP. The maximum speed set by FMX command execution remains
in effect until it is reset by the next FMX command.
The maximum feed speed for interpolation is not yet set at the moment the program operation starts. It is neces-
sary to execute an FMX command before executing any of the following interpolation related commands.
• Linear Interpolation command (MVS)
• Circular Interpolation command (MCW, MCC)
• Helical Interpolation command (MCW, MCC)
• SKP command (Linear interpolation with skip function) (SKP)
• Interpolation Feed Speed Ratio Setting command (IFP)
• Interpolation Acceleration Time Change command (IAC)
• Interpolation Deceleration Time Change command (IDC)
Fig. 8.16 Maximum Interpolation Feed Speed Setting Command (FMX)
• Execution of any interpolation related command is subject to the preset maximum feed speed for interpolation. For
example, the Interpolation Acceleration Time Change command (IAC) and the Interpolation Deceleration Time Change
(IDC) set the time required to reach the maximum feed speed for interpolation from the speed of 0.
• Executing an interpolation related command MVS, MCW, MCC, SKP, IFP, IAC, or IDC without first having executed
an FMX command will cause an alarm in the motion program.
