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 10% for input interface.
Driver power input terminal for digital interface.
COM of each connector is connected in the servo amplifier.
When using an external power supply, connect a power supply of
24VDC, 200mA or more to this terminal.
P15R 11 Used to output 15VDC to across P15R-LG. Used for VC/TLA power
supply.
SG 10, 20 24VDC common terminal for VDD, COM, etc. and isolated from LG.
LG 1 Common terminal for VC, TLA, MO1, MO2 and P15R.
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 or LSN-SG. When they are opened,
the servo motor is stopped suddenly and servo-locked.

ST1 8 This signal serves as a forward rotation start signal for the
incremental value command system.
In automatic operation mode, the servo motor rotates in the forward
rotation direction as soon as ST1-SG are shorted.
In zeroing mode, zeroing 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.
This signal serves as a start signal for the absolute value command
system. In automatic operation mode, operation starts as soon as
ST1-SG are shorted.
In zeroing mode, zeroing 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.
ST2 9 In automatic operation mode, the servo motor rotates in the reverse
rotation direction as soon as ST2-SG are shorted. (Incremental value
command only)
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.
