When using a manual pulse generator, supply 24VDC to this
terminal.
Digital I/F common
SG
10, 20 Common terminal for VDD and COM and isolated from LG.
DC15V power supply
P15R
4
Used to output 15VDC. Power supply terminal for VC and TLA.
Control common
LG
1
Common terminal for VC, TLA, MO1, MO2 and P15R.
When terminals DOG-SG are shorted, the proximity dog signal is
detected. The polarity of dog detection input can be changed with the
parameter.
Parameter No.8
Polarity of Proximity Dog Detection Input
0
DOG-SG are opened.
1 (initial value) DOG-SG are shorted.

Zeroing completion
ZP
18
ZP-SG are connected on completion of zeroing.
In the absolute position system, ZP-SG are connected when the servo
amplifier is ready to operate but are disconnected if:
1) SON-SG are opened;
2) EMG-SG are opened;
3) RES-SG are shorted;
4) Alarm occurs;
5) Limit switch opens;
6) Zeroing has not been made after the purchase of the product;
7) Zeroing has not been made after the occurrence of absolute position
erasure (A. 25) or absolute position counter warning
(A. E3);
8) Zeroing has not been made after the changing of the electronic gear
value;
9) Zeroing has not been made after the absolute position system was
made valid; or
10) The ST1 coordinate system (000 in parameter No.1) has been
changed.
