6.23 Spindle Orientation
6.23.1 Outline
(1) Orientation
This function stops the spindle rotation at a certain position when using the digital spindle.
When the orientation command is used, the spindle will rotate several times and then stop at the orientation point.
The orientation position differs depending on the detector.
- When the encoder orientation (PLG and external encoder/ring sensor) is used:
...At the Z-phase position
- When the magnetic sensor (proximity switch) is used:
...At the magnetic sensor installation position
(2) Multi-point orientation
This function performs orientation to a position other than the Z-phase position by inputting a shift amount with the
parameter or PLC. The shift amount is 0 to 35999.(Unit

)
(Note 1) Multi-point orientation cannot be executed when using the magnetic sensor.
(Note 2) Orientation is possible only when the gear ratio is 1:1 for the PLG orientation.
(The orientation is completed at the PLG encoder's Z-phase, so when using reduction gears, the orientation
points will be generated at several points during one spindle rotation.)
(3) Orientation in-position advance output
This function turns the spindle in-position signal ON as soon as the spindle reaches within the second in-position width
(parameter "#3132 ori_inp2" (2nd in-position width for orientation)). Then, the spindle 2nd in-position signal is turned ON
as soon as the spindle reaches within the in-position width (parameter "#13024 SP024 INP" (In-position width)).
Since orientation completion can be predicted using this function, it is possible to eliminate the sequence delay time, etc.
for tool changes and other such operations, thereby achieving a faster tact time.
