3.3.2 Signal explanations
1) CN1A
Signal Name Symbol Pin No. Description I/O Division
Digital I/F power supply
input COM 9 Used to input 24VDC (200mA or more) for input interface.
Connect the positive ( ) terminal of the 24VDC external power
supply.
24VDC 10%
Open collector power
input OPC 11 When inputting a pulse train in the open collector system, supply
this terminal with the positive ( ) power of 24VDC.
Digital I/F common
SG 10, 20 Common terminal for input signals such as SON and EMG. Pins are
connected internally.
Separated from LG.
15VDC power supply
P15R 4 Outputs 15VDC to across P15R-LG. Available as power for TC, TLA,
VC, VLA.
Permissible current: 30mA
Control common
LG 1 Common terminal for TLA, VC, OP ,MO1, MO2 and P15R.
Pins are connected internally.
PP 3 Manual pulse generator
NP 2
Used to connect the manual pulse generator (MR-HDP01). (Refer to
Section 14.1.6.)
When terminals DOG-SG are shorted, the proximity dog (DOG) is
detected. The polarity of dog detection input can be changed with the
parameter.
Parameter No.8 Polarity of Proximity Dog Detection Input
0 (initial value) DOG-SG are opened.
1 DOG-SG are shorted.
Proximity dog DOG 8 DI-1
Home position return
completion ZP 18 ZP-SG are connected on completion of home position return.
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) Home position return has not been made after the purchase of the
product;
7) Home position return has not been made after the occurrence of
absolute position erasure (A. 25) or absolute position counter
warning
(A. E3);
8) Home position return has not been made after the changing of the
electronic gear value;
9) Home position return 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.
When the status is not any of 1) to 10) and home position setting has
already been completed at least once, the home position return
completion (ZP) is in the same output status as the ready (RD).
