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 length compensation value, cutter compensation 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.
AOFS2 AOFS1 Offset value to be changed
0 0 Tool length compensation value
0 1 Cutter compensation value
1 0 Workpiece origin offset
Active offset value change in-progress signal MCHAO<Fn297#5>
[Classification] Output signal
[Function] Posts that the active offset value change mode based on manual feed is
selected and an offset value is being changed.
[Output condition] When all of the following conditions are satisfied, this signal is set to
1:
- The active offset value change mode signal CHGAO <Gn297#4>
is set to 1.
- The automatic operation halt state or automatic operation stop
state is set (with STL<F000#4> set to 0).
NOTE
Before restarting automatic operation, be sure to
check that this signal is set to 0.
