Control I/O signal
3) Position Table A0 –A7 (PT A0~A7) Input
The position table supports the machine so that its motion can be controlled by I/O signals
of central controller. It can directly transmit commands such as position table number,
start/stop and origin return to the machine through the PLC. Also, the user can check output
signals such as in-position, completion of origin return and STEP ready through the PLC.
「Position Table A0~A7」 Inputs are total 8 bits of input signal. It is used to set
256 position
table numbers. There are two application methods as follows
1) To set position table number (0~255) to be set by ‘PT start’ input signal.
2)
To set position table number (0~255) to save current position values by ‘Teaching’ input
signal.
By using PT A0~A7 signals, the position table address can be set from 0 to 255 with a binary
number. A0 is least significant bit and A7 is most significant bit. The following table shows how
to assign position table number.
*1. Save signal cabling: If ‘PT A0~A7’signal is not connected when motioning by
‘PT Start’ signal, the position table number will be ‘0’.
A7 A6 A5 ~ A3 A2 A1 A0 PT No

0 0 0 0 0 1 1
0 0 0 0 1 0 2

*2. ‘PT A5/UserIN 6’ ‘PT A6/UserIN 7’ ‘PT A7/UserIN 8’ signal setting :
This signal can be used as ‘PT A5~A7’, and also can be used as
‘User IN6~IN8’signal when the input signal ‘User IN0~IN5’is not enough.
