Axis Fixed-Pitch Feed Control
Positioning control for specified axis of specified travel value from the current stop point.
Fixed-pitch feed control uses the FEED-1servo instruction.
: Must be set,
: Set if required
*1 Only when the reference axis speed is specified
Processing details
• Positioning control for the specified travel value from the current stop position "0" is executed.
• The travel direction is set by the sign (+/ -) of the travel value, as follows:
Do not set the travel value to "0" for fixed-pitch feed control.
If the travel value is set to "0", fixed-pitch feed completion without fixed-pitch feed.
