� Functional description(standard PLC program definition)
1. After the positioning function commands M51~M58 are executed, PLC→Drive executes
the
orientation selection signal SP0, SP1, SP2 to confirm the orientation position.
2. Delay 40ms, PLC→Drive executes the spindle orientation start signal STAO；（ after the
system
delays 100ms, the spindle rotation(CW/CCW) is disabled, at the same time, the system
starts to
check the orientation completion signal (COIN）.
3. Drive unit starts the orientation.
4. After the drive unit orientation is completed, Drive →PLC outputs the spindle
completion signal
COIN;
5. After PLC receives the spindle orientation completion signal COIN, the spindle
orientation is
completed, but the spindle orientation signal STAO keeps the output.
6. When M51~M58 is input again, the spindle oriented to another position.
7. After the orientation is completed and when M50 is executed or the spindle orientation
is
operated, PLC closes the spindle orientation signal STAO output and the drive unit
cancels the
positioning function.
8. When the system has not received the orientation completion signal after the PLC
sends the
orientation completion signal for 10000ms, it alarms “the spindle orientation time being
long”.
9. Before the orientation, the spindle can rotate or stop; the spindle stops after the
orientation.
Note 1: The drive is for the spindle servo drive unit.
Note 2: When the function is selected, the spindle servo drive unit is matched and is valid in the
