Reverse rotation
start ST2 CN3-4 Point table method
Use this device with the incremental value command method. When ST2 is
turned on during automatic operation, positioning is executed once in the
reverse rotation in accordance with the position data set in the point tables.
Turning on ST2 during JOG operation will rotate the servo motor in the
reverse rotation direction while ST2 is on. Turning on both ST1 and ST2
stops the servo motor.
When ST2 is turned on in the home position return mode, automatic
positioning is executed to the home position.
The reverse rotation indicates the address decreasing direction.
Turning on both ST1 and ST2 during JOG operation stops the servo motor. DI-1
Indexer method
This device is not used.
Temporary stop/
restart TSTP When TSTP is turned on during automatic operation, the operation stops
temporarily.
When TSTP is turned on again, the operation resumes.
Turning on ST1 (Forward rotation start) or ST2 (Reverse rotation start)
during a temporary stop does not rotate the servo motor.
When the automatic operation mode is changed to the manual operation
mode during a temporary stop, the travel remaining distance will be erased. DI-1
Proximity dog DOG When DOG is off, a proximity dog is detected. The polarity for dog detection
can be changed with [Pr. PT29]. DI-1

The polarity for SIG can be changed with [Pr. PT29].
1. Homing mode (MD1 = 0, MD0 = 0)
SIG can be used as an input device of external limit. This operation
mode is enabled when the homing type of the torque limit changing dog
type is selected.
2. Manual operation mode (MD1 = 0, MD0 = 1)
You can use this as an input device for specifying a rotation direction of
the servo motor. The rotation direction varies depending on the setting
of [Pr. PA14 Rotation direction selection]. (Refer to table 12.1.)
3. Automatic operation mode 1 (rotation direction specifying indexer) (MD1
= 1, MD0 = 0)
You can use this as an input device for specifying a rotation direction of
the servo motor. The rotation direction varies depending on the setting
of [Pr. PA14 Rotation direction selection]. (Refer to table 12.1.)
4. Automatic operation mode 2 (shortest rotating indexer) (MD1 = 1, MD0
= 1)
SIG can be used as an input device for selecting the speed of the servo
motor.
