The methods of designating speed commands, accelerations/decelerations, overrides, and so on, are all the
same as for linear interpolation. For details, see 2.1.2 LINEAR INTERPOLATION (MVS).

* Example of MP930
The interpolation override setting differs depending on the Machine Controller mod-
el. Refer to 1.2.3 Feed Speeds for details.
1. The speed designation (F) must be specified in the same block as the interpolation command.
2. The INTERPOLATION FEED SPEED RATIO SETTING command (IFP) is an isolated command, and
cannot be specified in the same block as the interpolation command.
3. If the override applied to the F designation results in a speed exceeding the maximum interpolation feed
speed (FMX), the speed will be clamped to the FMX speed.
