bitE. Sub-motor selection command (MS)
This command input signal is used to select sub-motor when changing over 1-drive unit 2-motor
(spindle motor/general purpose motor).
MS Explanation
1
(ON)
Sub-motor is selected.
0
(OFF)
Main-motor is selected.
<<For MDS-C1-SPM>>
bitE. M coil selection command (MCS)
This command is input to select medium-speed coil when using the medium-sp eed coil.
MCS Explanation
1
(ON)
Medium-speed command is selected.
0
(OFF)
High-speed command is selected.
bitF. Position changeover mode selection (PCHG)
This command is input to select changeover operation from speed control to position control
(synchronous tap control, C-axis control and spindle synchronous control.)
PCHG Explanation
1
(ON)
No zero point return is selected.
0
(OFF)
With zero point return is selected.

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.

Standard
SP056 PYVR Variable excitation
(min value)
Set the minimum value of the variable excitation rate.
Select a smaller value when gear noise is too high.
Lager value is more effective on impact response.

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.

Setting
range
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.
0 to 32767

0
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).
0 to 32767

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