5 - 7
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.
bitA. Indexing forward run command (WRN)
bitB. Indexing reverse run command (WRI)
This is valid when the orientation start command is ON.
WRN Explanation WRI Explanation
1 (ON)
Indexing is carried out in the
counterclockwise (CCW) direction
looking from the motor end.
1 (ON)
Indexing is carried out in the clockwise
(CW) direction looking from the motor
end.
0 (OFF) Indexing is not carried out. 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.
