7709 Number of the axial feed axis for helical compensation
[Input type] Parameter input
[Data type] 2-word path
[Valid data range] 0 to Number of controlled axes
This parameter sets the number of the axial feed axis for a helical gear.
NOTE
When this parameter is set to 0 or a value outside
the valid setting range, the Z-axis is used as the
axial feed axis.
When there are two or more Z-axes in parallel, use
this parameter to specify the axis to be used as the
axial feed axis.
7717 Synchronization cancellation delay time for an EGB axis
[Input type] Parameter input
[Data type] Word axis
[Unit of data] 0.1sec
[Valid data range] 0 to 32767 (0 to 3276.7sec)
If a servo alarm is issued during EGB synchronization, the tool may
be retracted due to the servo alarm. At this time, when the tool has
been retracted along the specified axes and the time set in this
parameter has elapsed after the servo alarm is issued, EGB axis
synchronization is canceled.
This parameter is also valid when a servo alarm is issued for an axis
along which to retract the tool.
When this parameter is set, the output of the retract completion signal
RTRCTF is also delayed.
NOTE
Servo position control including EGB axis
synchronization stops 400 ms after the output of
the retract completion signal RTRCTF.
This parameter is invalid in either of the following
cases:
1) When a servo alarm is issued for an axis for
which EGB synchronization is performed
2) When excitation is cut for an axis sharing the
same amplifier with the axis for which EGB
synchronization is performed due to a servo
alarm
