8.5 DIAMETER AND RADIUS SETTING SWITCHING
FUNCTION
Overview
Usually, whether to use diameter specification or radius specification
to specify a travel distance on each axis is uniquely determined by the
setting of bit 3 (DIAx) of parameter No. 1006. However, this
function enables switching between diameter specification and radius
specification by using a signal or G code.
Thus, a coordinate, program, and so forth can be specified by
switching between diameter specification and radius specification for
each controlled axis.
Explanation
- Selection of a diameter/radius specification switching method
Two methods are available for switching between diameter
specification and radius specification:
1) Signal
2) G code
Use bit 5 (PGD) of parameter No. 3400 to determine which method to
use.
- Switching method using a signal
For switching between diameter specification and radius specification,
set the diameter/radius specification switch signal from DI1 to DI8
(input signals) corresponding to a desired axis, from 0 to 1.
If an input signal is set from 0 to 1, and radius specification is selected
(with bit 3 (DIAx) of parameter No. 1006 = 0) for the axis
corresponding to the input signal, the specification method switches to
diameter specification; the specification method switches to radius
specification if diameter specification is selected (with bit 3 (DIAx) of
parameter No. 1006 = 1).
During switching, the diameter/radius specification switching
in-progress signal from DM1 to DM8 (output signals) corresponding
to a switched axis is output.
To return the diameter/radius specification of an axis to the original
state, set the setting of the corresponding diameter/radius specification
switch signal from DI1 to DI8, from 1 to 0.
