bit8. Forward run start command (SRN)
This is an operation command. The speed command must also be designated to rotate the motor.
If the orientation command is input, the orientation operation will have the priority.
SRN Explanation
1 (ON)
The motor rotates in the counterclockwise direction (CCW) looking
from the shaft at the commanded speed.
0 (OFF)
The motor decelerates to a stop.
After stopping, the drive unit's power module turns OFF.
bit9. Reverse run start command (SRI)
This is an operation command. The speed command must also be designated to rotate the motor.
If the orientation command is input, the orientation operation will have the priority.
SRN Explanation
1 (ON)
The motor rotates in the clockwise direction (CW) looking from the
shaft at the commanded speed.
0 (OFF)
The motor decelerates to a stop.
After stopping, the drive unit's power module turns OFF.

0
(OFF)
Indexing is not carried out.
bitC. Orientation start command (ORC)
This signal is used to start orientation. Orientation has a priority when the orientation start
command is input.
ORC Explanation
1 (ON) Orientation starts regardless of the run command (SRN, SRI).
0 (OFF)
When a run command (SRN, SRI) is selected, the rotation starts again
at the commanded speed.
bitD. L coil selection command (LCS)
This command is input to select the coil method for changing the coil. Note that coil changeover is
not possible when orientation is commanded. The coil is fixed when the orientation command is
input.
LCS Explanation
1 (ON) The low-speed command is selected.
0 (OFF) The high-speed command is selected.

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.
