When the MD0 is turn on, the automatic operation mode is set. When the
CN3-4 MD0 is turn off, the manual operation mode is set. Changing an operation
mode during operation clears the command remaining distance and the
motor decelerates to stop.
MD1 cannot be used.

CN3-3 Point table method
1. Absolute value command method
When ST1 is turned on during automatic operation, positioning is
executed once in accordance with the position data set in the point
tables.
Turning on ST1 during homing also starts home position return.
Turning on ST1 during JOG operation rotates the servo motor in the
forward rotation direction while ST1 is on.
The forward rotation indicates the address increasing direction.
Turning on both ST1 and ST2 during JOG operation stops the servo
motor.
2. Incremental value command method
When ST1 is turned on during automatic operation, positioning is
executed once in the forward direction in accordance with the position
data set in the point tables.
Turning ST1 on during homing also starts home position return.
Turning on ST1 during JOG operation rotates the servo motor in the
forward rotation direction while ST1 is on.
The forward rotation means the address increasing direction.
Turning on both ST1 and ST2 during JOG operation stops the servo
motor.
Indexer method
1. Automatic operation mode 1 or automatic operation mode 2
Turning on ST1 will execute one positioning to the specified station No.
2. Manual operation mode
Turning on ST1 with the station JOG operation will rotate the motor in
the specified direction with SIG only while it is on. Turning off ST1 will
execute a positioning to a station which can be decelerated to a stop.
Turning on ST1 with JOG operation will rotate the motor in the direction
specified with SIG only while it is on. Turning off will decelerate the
motor to a stop regardless of stations.
3. Home position return mode
Turning on ST1 will also start home position return.
