bit2. Up-to-speed (US)
This signal turns ON when the start command signal (forward run, reverse run) is ON, and the
motor speed has reached a range of ±15% (standard value) of the speed command value. This
signal turns OFF when the start command signal turns OFF. The up-to-speed output range can b e
set with the parameter SP048 (SUT). Even though the setting value is small, the output will be
±45r/min. Pay attention when speed command value is small.

bit3. Zero speed (ZS)
Regardless of the input signal state, this signal turns ON when the motor speed drops below the
value set with parameter SP018 (ZSP). Once this signal turns ON, it will not turn OFF for at least
200ms. When switching ON to OFF, hysteresis width is 15r/min. Note that if the parameter SP018
(ZSP) setting value is too small (approx. 10r/min or less), this signal may not be output even if the
motor is stopped.

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 spindl e synchrono us control, when the mode can be changed fro m 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.
