Additional Manual
Example
Assume the following conditions:
• Specified workpiece coordinate system: G56
• G56 workpiece origin offset (X-axis): 50.000
• G56 workpiece origin offset (Z-axis): 5.000
• G56 workpiece origin offset (C-axis): 180.000
• G56 workpiece origin offset (Y-axis): -60.000
• Amount of manual feed-based movement along the X-axis: -10.000 mm
• Amount of manual feed-based movement along the Z-axis: 10.000 mm
• Amount of manual feed-based movement along the C-axis: 90.000 degrees
• Amount of manual feed-based movement along the Y-axis: -5.000 mm
Under the above conditions, the workpiece origin offset for G56 is changed
as follows:
• X-axis: 50.000 + (-10.000) = 40.000
• Z-axis: 5.000 + 10.000 = 15.000
• C-axis: 180.000 + 90.000 = 270.000
• Y-axis: -60.000 + (-5.000) = -65.000
2.5 Presetting the relative position indicator
Setting parameter APL (No. 3115#5) to 1 can preset the relative position
indicator (counter) to 0 automatically when active offset change mode is selected.
In this case, performing manual feed until the relative position indicator
(counter) becomes 0 can restore the changed offset value to the previous one.
2.6 Tool life management
If a tool management option is available, compensation is carried out by the T
code (Txx99). In this case, a change is made to the compensation corresponding
to the compensation number made valid by this command.
2.7 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 compensation has been selected as an offset to be changed, follow-up-caused
axis movement around a rotation axis is not reflected to the offset
