bitB. Minimum excitation rate changeover request (PYVC)
This command selects the minimum excita tion rate of weak excitation control.
When SP033/bit8=1, the minimum excitation rate changes over from SP056 to SP116 by turning
ON this signal.

bitC. Orientation speed changeover request (OSPC)
This command selects clamp speed for the orientation changeover operation.
When the orientation is started with control input 3/bitC(ORC)=1, the clamp speed changes over
from SP005 to SP115 by turning ON this signal.

bit0. In READY ON (RON)
When the READY ON signal is input from the NC, if there is no abnormality, this signal turns on in
approx. one second. If the start sign al (forward run, reverse run, orientation) is turne d ON while this
signal is ON, the motor will start rotating. If an alarm occurs in the spindle drive unit, this signal will
turn OFF. If the READY ON signal from the NC turns OFF while the spindle motor is rotating, the
motor will decelerate to a stop, but this signal will remain ON until the motor stops.
bit1. In servo ON (SON)
This signal turns ON after position control is switched when performing position control except for
the orientation.
bit4. In drive unit warning (WRN)
This signal turns ON when a warning is occurring in the spindle drive unit.
bit6. In parameter conversion (PRMA)
The parameters sent fro m the NC are converted into effective parameters for spindle control.
bit7. In drive unit alarm (ALM)
This signal turns ON when an alarm is occurring in the spindle drive unit.
bit8. In torque limit 1 signal input (TL1A)
bit9. In torque limit 2 signal input (TL2A)
bitA. In torque limit 3 signal input (TL3A)
The respective signal turns ON when the torque limit signal 1 to 3 is input.
