c. The feed speed upper limit is restricted by machine and servo performance. Set
the upper limit of the feed speed by the following motion commands.
An alarm results if the value of the F command exceeds the maximum interpola-
tion feed speed.
Important Point
If interpolation commands are to be used, an FMX command must be used at the start
of a motion program.
d. F Command Units
Decimal places cannot be used in F command values.
e. It is possible to switch the interpolation feed speed override within a range of
0~32,767%. Set the override setting in the register (default = MW00001) defined
in the Group Definitions Screen. There are three override setting methods:
motion program, ladder program, and setup parameter screen.
