The motion commands relating to the interpolation feed speed are shown below.
D F designation F designation in interpolation command
D IFP command INTERPOLATION FEED SPEED RATIO SETTING
D FMX command MAXIMUM INTERPOLATION FEED SPEED SETTING
D IAC command INTERPOLATION ACCELERATION TIME CHANGE
D IDC command INTERPOLATION DECELERATION TIME CHANGE
D SCC command S-CURVE TIME CONSTANT CHANGE
1. The Override setting is always effective during operation.
2. When the output speed is out of range after adjustment the override setting data, it will be clamped at the
FMX value.
1. If a rotary axis is included as an axis for an interpolation command, the mechanical travel speed will not
be the tangential speed for the F designation.
2. If “FO” is specified in the F designation, a program error will result.
3. Do not specify an F designation with a minus sign (F-jjj). Doing so will cause an alarm to be gener-
ated.
