5. Spindle Adjustment
5 - 23
bit4. Orientation complete (ORCA)
This signal turns ON when the orientation command is input, and the spindle position is reached
the set range (within the in-position range) in respect to the target stop position. This signal turns
OFF when orientation is completed and the spindle position deviates from the in-position range,
but it will turn ON again when the spindle position enters the in-position range again. If the
orientation command is turned OFF, this signal will turn OFF even if the spindle position is within
the in-position range. The in-position range can be set with parameter SP004 (OINP).

bit5. Synchronous speed match (SYSA)
This signal turns ON during spindle synchronous control, when the mode can be changed from the
speed operation mode to the spindle synchronous operation mode.
bit6. Changing coil (MKC)
When using the coil changeover motor, this signal turns ON for the time set in parameter SP059
(MKT) when the L coil selection command is turned ON or OFF. The coil is not changed when the
orientation command is input, so this signal will not turn ON even if the L coil selection signal is
turned ON or OFF. During orientation control, this signal will turn ON when the orientation
command turns OFF and the coil changeover operation takes place. Do not turn the start signal
ON or OFF while this signal is ON.
