CN1-17 Point table method
1. Absolute value command method
Turning on ST1 during automatic operation will execute one positioning
based on position data set in point tables.
Turning on ST1 during home position return will also start home
position return.
Turning on ST1 during JOG operation will rotate the motor in the
forward rotation direction while it is on.
The forward rotation means address increasing direction.
Turning on both ST1 and ST2 during JOG operation will stop the servo
motor.
2. Incremental value command method
Turning on ST1 during automatic operation will execute one positioning
in the forward rotation direction based on position data set in point
tables.
Turning on ST1 during home position return will also start home
position return.
Turning on ST1 during JOG operation will rotate the motor in the
forward rotation direction while it is on.
The forward rotation means address increasing direction.
Turning on both ST1 and ST2 during JOG operation will stop the servo
motor.
Program method
1. Automatic operation mode
Turning on ST1 will execute a program operation selected with DI0 to
DI7.
The forward rotation means address increasing direction.
Turning on both ST1 and ST2 during manual operation mode will stop
the servo motor.
2. Manual operation mode
Turning on ST1 will rotate the motor in the forward rotation direction
while it is on.
The forward rotation means address increasing direction.
Turning on both ST1 and ST2 during manual operation mode will stop
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.
CN1-18 Point table method
Use this device with the incremental value command method. Turning on
ST2 during automatic operation will execute one positioning in the reverse
rotation direction based on position data set in point tables. Turning on ST2
during JOG operation will rotate the motor in the reverse rotation direction
while it is on. Turning on both ST1 and ST2 will stop the servo motor.
Turning on ST2 during in the home position return mode will execute an
automatic positioning to the home position.
The reverse rotation means address decreasing direction.
Turning on both ST1 and ST2 during JOG operation will stop the servo
motor.
Program method
Turning on ST2 with JOG operation in the manual operation mode will
rotate the motor in the reverse rotation direction while it is on. Turning on
both ST1 and ST2 will stop the servo motor.
The reverse rotation means address decreasing direction.
Turning on both ST1 and ST2 during manual operation mode will stop the
servo motor. ST2 will be disabled in the automatic operation mode.
