7751
Amount of retraction performed when an alarm is issued
[Data type] 2–word axis
[Unit of data]
Unit of data
Increment system
IS–B IS–C
Metric input 0.001 mm 0.0001 mm
Inch input 0.0001 inch 0.00001 inch
[Valid data range] –99999999 to 99999999
This parameter sets the amount of retraction performed when an alarm is
issued. Whether to perform the retraction depends on the setting of bit 3
(ART) of parameter No. 7702.
7771
Number of EGB axis
NOTE
After setting this parameter, turn off the power. Then, turn
the power back on to enable the setting.
[Data type] Byte
[Valid data range] 1 to the number of controlled axes
This parameter specifies the number of the EGB axis.
NOTE
1 You cannot specify four because the fourth axis is used as
the workpiece axis.
2 Can not set same number that is used as the workpiece axis.
7772
Number of position detector pulses per rotation about tool axis
[Data type] 2–word
[Data unit] Detection unit
[Valid data range] 1 to 99999999
This parameter specifies the number of pulses per rotation about the tool
axis (on the spindle side), for the position detector.
NOTE
Specify the number of feedback pulses per rotation about
the tool axis for the position detector, considering the gear
ratio with respect to the position coder.
