Appendix A, Command Function Reference
This appendix provides detailed information for each setup and dispense command. Commands are in alphabetical
order.
The following rules apply to all commands:
• A command is in effect until it is superseded by another command.
• Command settings override system settings.
Acceleration
Click
Function
Controls the acceleration of the robot from point to point (ptp) or along a continuous path (cp). In general, the
value of this parameter is inversely related to the robot’s acceleration.
Parameter
Description
0:ptp 1:cp
Toggles the acceleration control between point to point (ptp) or continuous path (cp).
Value
Sets the rate of acceleration from point to point or on a continuous path.
Range: 20–600 (mm/s
2
)
Arc Point
Click
Function
Registers the current XYZR location as an Arc Point. Arc Points dispense fluid along an arched path.
Backtrack Setup
Click
Function
Sets how the dispensing tip raises at the end of line dispensing. This is useful for high-viscosity or stringy fluids
to control where the fluid tail falls. The illustrations on the next page provide a visual representation of the
Backtrack Setup selections.
Parameter
Description
Backtrack Length
Distance the dispensing tip travels away from the Line End point.
Backtrack Gap
Distance the dispensing tip raises as it moves away from the Line End point. This value
must be less than the Z Clearance value for that point.
Backtrack Speed
Speed at which the dispensing tip moves either (1) back and up along the retract path
to reverse direction after line dispensing or (2) forward and up at an angle after line
dispensing.
Type
0 or blank (Normal) The dispensing tip moves straight up for the height entered for
Backtrack Gap.
1 (Back)
The dispensing tip moves backward at an angle for the distance and
height entered for Backtrack Length and Backtrack Gap.
2 (Square Back)
The dispensing tip moves up and then back at the distance and
height entered for Backtrack Length and Backtrack Gap.
3 (Forward)
The dispensing tip moves forward at an angle for the distance and
height entered for Backtrack Length and Backtrack Gap.
4 (Square Forward) The dispensing tip moves up and then forward for the distance and
height entered for Backtrack Length and Backtrack Gap.
