LSP CN1B To start operation, short LSP-SG and/or LSN-SG. Open them to bring the motor to
16 a sudden stop and make it servo-locked.

(Refer to section 5.2.5.)
LSN CN1B

ST1 CN1B 1. In the case of the absolute value command system.
8 When ST1-SG are shorted in the automatic operation mode, positioning is
executed once on the basis of the position data set to the point table.
In home position return mode, home position return starts as soon as ST1-SG
are shorted.
In jog operation mode, the servo motor rotates in the forward rotation direction
while ST1-SG are shorted.
2. In the case of the incremental value command system.
When ST1-SG are shorted in the automatic operation mode, positioning is
executed once on the basis of the position data set to the point table.
In home position return mode, home position return starts as soon as ST1-SG
are shorted.
In jog operation mode, the servo motor rotates in the forward rotation direction
while ST1-SG are shorted.
Forward rotation denotes the direction in which the address is incremented.
3. In absolute value command /incremental value command specifying system
When ST1-SG are shorted in the automatic operation mode, positioning is
executed once on the basis of the position data set to the point table.
In home position return mode, home position return starts as soon as ST1-SG
are shorted.
In jog operation mode, the servo motor rotates in the forward rotation direction
while ST1-SG are shorted.
ST2 CN1B This device is used in the incremental value command system.
9 When ST2-SG are shorted in the automatic operation mode, positioning is executed
once in the reverse rotation direction on the basis of the position data set to the
point table.
In jog operation mode, the servo motor rotates in the reverse rotation direction
while ST2-SG are shorted.
Reverse rotation denotes the direction in which the address is decremented.
The reverse rotation start (ST2) is also used as the start signal of the function to
perform high-speed positioning to the home position. (Refer to section 4.4.11.)
MD0 CN1B Short MD0-SG to choose the automatic operation mode, or open them to choose the
7 manual operation mode.
DOG CN1A When terminals DOG-SG are shorted, the proximity dog signal is detected. The
8 polarity of dog detection input can be changed with the parameter.
