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.

Standard
SP005 OSP* Orientation mode
speed clamp value
Set the motor speed limit value to be used when the speed loop
is changed to the position loop in orientation mode.
When this parameter is set to "0", SP017 (TSP) becomes the
limit value.

SP115 OSP2 Orientation control
speed clamp value 2
When the orientation clamp speed is changed by the control
input, this parameter setting will be used instead of SP005:
OSP.
Indexing speed clamp valid
This parameter is used when (SP097: SPEC0/bit4 = 1).

bitF. Spindle holding force up (TLUP)
The disturbance observer starts, and the servo rigidity increases. Refer to "5-3-5 (3) Disturbance

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.

bitB. Magnetic pole position checked (MAO)
This signal turns ON when magnetic pole position is checked.
bitD. Z-phase passed (ZFIN)
This signal turns ON when the Z-phase is passed for the first time after servo ON during position
control.
bitE. In position loop in-position (INP)
During position loop control, this signal turns ON if the position droop drops below the value set
with SP153 (CINP) during C-axis control, SP185 (SINP) during spindle synchronous control, and
SP217 (TINP) during synchronous tap control.

bitF. Limiting current (CL)
This signal turns ON if a load higher than the spindle's excessive load withstand level is applied
during spindle motor rotation. This may also turn ON during motor acceleration/deceleration.
