Signal
Active offset value change mode signal CHGAO<Gn297#4>
[Classification] Input signal
[Function] Selects the active offset value change mode based on manual feed.
[Operation] If all of the following conditions are satisfied, the active offset value
change mode based on manual feed is set by setting this signal to 1:
- The automatic operation halt state or automatic operation stop
state is set (with STL<F000#4> set to 0).
- The manual handle feed mode, incremental feed mode, jog feed
mode is selected.
If a movement on an axis is made by manual handle feed, incremental
feed, or jog feed in this mode, the offset value currently valid among
the offset values selected with the active offset selection signals
AOFS1 and AOFS2 <G297#5 and #6> is changed by the travel
distance moved on the axis.
By setting bit 5 (APL) of parameter No. 3115 to 1, the relative
position indication (counter) can be preset to 0 when the active offset
value change mode is selected with this signal. In this case, a
changed offset value can be restored to the original value by returning
by manual feed to the position represented by a relative position
indication (counter) of 0.
Active offset selection signal AOFS1<Gn297#5>, AOFS2<Gn297#6>
[Classification] Input signal
[Function] Selects a type of offset value to be changed in active offset value
change operation based on manual feed.
[Operation] From tool offset value, and workpiece origin offset, choose a type of
offset value to be changed by active offset value change operation
based on manual feed according to the table below. An offset value
to be changed can be selected by setting bit 1 (ATP) of parameter No.
5041.
Parameter ATP AOFS2 AOFS1 Offset value to be changed
0 - Tool offset value
0
1 - Workpiece origin offset value
0 0 X-axis offset value
0 1 Z-axis offset value
1 0 Workpiece origin offset value
1
1 1 Y-axis offset value
NOTE
To change the tool offset value for the Y-axis, the
option for Y-axis offset is required.
