Temporary
stop/restart TSTP Turning on TSTP during automatic operation will temporarily stop the
motor.
Turning on TSTP again will restart.
Turning on ST1 (Forward rotation start)/ST2 (Reverse rotation start) during
a temporary stop will not rotate the motor.
Changing the automatic operation mode to manual operation mode during
a temporary stop will erase a travel remaining distance.
The temporary stop/restart input will not function during home position
return/JOG operation. DI-1
Proximity dog DOG CN1-45 Turning off DOG will detect a proximity dog. The polarity for dog detection
can be changed with [Pr. PT29].

selection SIG CN1-45 The function varies depending on the operation mode.
1. Home position return mode (MD1 = 0, MD0 = 0)
You can use SIG as an input device of external limit. This operation
mode is enabled when the home position return 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 section 2.1.)
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 section 2.1.)
4. Automatic operation mode 2 (shortest rotating indexer) (MD1 = 1, MD0 =
1)
You can use SIG as an input device for selecting a speed of the servo
motor.
