- Emergency stop and SV alarm
If the servo power is switched off (for example, when the machine is
brought to an emergency stop or an SV alarm occurs), axis movement
caused by follow-up is reflected to the offset during active offset
change mode.
NOTE
If the tool length compensation or cutter
compensation has been selected as an offset to be
changed, follow-up-caused axis movement around
a rotation axis (that is, an axis for which parameter
No. 1022 is 0) is not reflected to the offset.
Restrictions
- Manual operations that cannot be used with active offset change
If a selected manual operation meets a condition listed below, the
manual feed-based active offset change mode cannot be selected. So,
such a manual operation cannot be used for active offset change.
1. Manual reference point return mode
2. Manual feed through an arbitrary angle
3. Three-dimensional handle feed (tool axial-direction handle mode,
tool radial-direction handle mode, tool tip center handle mode,
tool axial-direction tool length compensation change handle
mode)
4. Simultaneous automatic-manual operation
Signals
Active offset change mode signal CHGAO<G153#4>
[Classification] Input signal
[Function] This signal selects the manual feed-based active offset change mode.
[Operation] When all the following conditions are satisfied, setting this signal to
"1" selects the manual feed-based active offset change mode.
- Automatic operation is at pause or stop (STL<F000#4> is "0").
- Neither manual reference point return mode/manual feed through an
arbitrary angle/three-dimensional handle feed nor simultaneous
automatic-manual operation is selected.
If axis movement is performed based on manual handle feed,
incremental feed, or jog feed in this mode, the currently valid offset
that is selected with the active offset selection signal AOFS0 to
AOFS3<G153#4 to #7> is changed by the amount of axis movement.
Setting parameter APL (bit 7 of parameter No. 2214) to 1 presets the
relative position indicator (counter) to 0 automatically, when this
signal selects the active offset change mode. In this case, resetting the
relative position indicator (counter) to 0 by manual feed can restore the
previous value of the offset.
