Template 19: Two-Axis Cross Feed Cycle
Letter Paramacro Label Description
F
1
500 MAIN RAPID FEEDRATE The velocity of the tool as it approaches the part.
X
1
501 MAIN FEED START The position of the tool as it drills into the part.
F
2
502 MAIN FEEDRATE The velocity of the tool as it drills into the part.
X
2
503 MAIN FINAL POSITION The depth of the tool at its final position in the part.
F
3
504 CROSS FEEDRATE (MAX) The velocity of the tool as it traverses the part.
Y
1
505 CROSS FINAL POSITION The final position of the tool after it traverses the part.
X
3
506 MAIN RETURN POSITION The position of the tool when it started the cycle.
Y
2
507 CROSS RETURN POSITION The position of the slide when it started the cycle.
F
4
508 CROSS RETURN RAPID The velocity of the slide as it returns to its starting position.
E 509 ADAPTIVE FEED MINIMUM This is the minimum feedrate at which the control performs an adaptive feed operation.
The control will try to maintain this minimum feedrate, even if it means increasing the
adaptive feed torque percent. For more information on adaptive feed, refer to page 18-9.
Q 510 ADAPTIVE FEED TORQUE % This is the amount of the selected servo’s continuous rated torque as entered in AMP by
your system installer. Valid ranges are from 1 to 150% of the servo’s rated torque.
Refer to your system installer’s documentation for details on the rated torque of the
servos in your system.
Important: The torque amount applied by the servo is not the cutting force. It is the
torque applied by the servo to the axis. You must calculate the equivalent cutting force
based on your machine dynamics (motor rated torque, lead screw pitch, gearing, tool
dimensions, etc...).
Y 511 CROSS TOOL CHANGE POSITION The position the slide moves to so that a tool change may be performed.
X 512 MAIN TOOL CHANGE POSITION The position the tool moves to so that a tool change may be performed.
I 513 HARD STOP SENSE ZONE The position that indicates to the control that a hard stop is on the axis.
