Fixed-Pitch Feed Control Using 2 Axes Linear Interpolation - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

5.11
Fixed-Pitch Feed Control Using 2 Axes Linear
Interpolation
Fixed-pitch feed control using 2 axes linear interpolation from the current stop position with the specified 2 axes.
Fixed-pitch feed control using 2 axes linear interpolation uses the FEED-2 servo instruction.
: Must be set, : Set if required
Servo Positioning
instruction method
FEED-2 Incremental
*1 Only when the reference axis speed is specified
Processing details
• Positioning control from the current stop position "0" to the position which combined travel direction and travel value
specified with each axis is executed.
• The travel direction for each axis is set by the sign (+/ -) of the travel value for each axis, as follows:
Travel direction
Positive
Negative
Positioning direction
Forward direction
Y-axis
travel value
Reverse
direction
0
X-axis travel value
Current stop
position
Reverse direction
Do not set the travel value to "0" for fixed-pitch feed control.
The following results if the travel value is set to "0":
• If the travel value of both is set to "0", fixed-pitch feed completion without fixed-pitch feed.
