- 556 -
- Another example of determining the feedrate
If a specified feedrate exceeds the upper feedrate limit of AI contour
control (in parameter No. 8465), the feedrate is clamped at the upper
feedrate. The upper feedrate limit is clamped at the maximum
cutting feedrate (parameter No. 1432).
Limitation
- Conditions for temporarily canceling the AI contour control mode
If one of the commands listed below is issued in the AI contour
control mode, the AI contour control mode is canceled temporarily.
If the system becomes ready for AI contour control after it is canceled,
the AI contour control mode is restored automatically.
• Positioning (rapid traverse)
• Single direction positioning
• Spindle positioning
• Rigid tapping
• Hypothetical axis interpolation
• Threading (single type, combined type)
• Electric gear box
• When no move command is specified
• One-shot G code other than the following:
Tool offset
Cutter compensation vector retention
Cutter compensation corner rounding
Exact stop
- Functions that cannot be specified in the AI contour control mode
In the AI contour control mode, the functions listed below cannot be
specified. Before specifying these functions, turn off the AI contour
control mode; after the command ends, turn on the mode again.
• Threading
• Circular threading
• Variable lead threading
Threading, circular threading, and variable lead threading can be
specified in the AI contour control mode by setting bit 1 (THA) of
parameter No. 1611. However, the AI contour control mode is
automatically canceled.
