Symbol Pin No.
VDD 3 Used to output 24V 10% to across VDD-COM.
When using this power supply for digital interface, connect it with
COM.
Permissible current: 80mA
COM 13 Used to input 24VDC (200mA or more) for input interface.
Connect the positive ( ) terminal of the 24VDC external power
supply.
24VDC 10%
P15R 11 Outputs 15VDC to across P15R-LG. Available as power for TC, TLA,
VC, VLA.
Permissible current: 30mA
SG 10, 20 Common terminal for input signals such as SON and EMG. Pins are
connected internally.
Separated from LG.
LG 1 Common terminal for TLA, VC, OP, MO1, MO2 and P15R.
Pins are connected internally.
SON 15 When SON-SG are shorted, the base circuit is switched on and the
servo amplifier is ready to operate.
When they are opened, the base circuit is shut off and the servo
motor coasts.
LSP 16 To start operation, short LSP-SG and/or LSN-SG. Open them to
bring the motor to a sudden stop and make it servo-locked.

(Refer to Section 5.2.5.)
LSN 17
Note. 0: LSP/LSN-SG off (open)
1. In the case of the absolute value command system.
ST1 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.
Forward rotation denotes the direction in which the address is
incremented.
2. In the case of the incremental value command system.
When ST1-SG are shorted in the automatic operation mode,
positioning is executed once in the forward rotation direction 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.
