8.3 Input Signal

1) Limit Sensor and Origin Sensor
Limit sensors and origin sensor are assigned to LIMIT+, LIMIT- , and ORIGIN pin in
the CN1 connector respectively. LIMIT+ and LIMIT- sensors are used to limit the
motion of each axis clockwise and counterclockwise to prevent mechanical collision.
Origin sensor is to set the origin of equipment.
2) Clear Pos
This input signal sets the command position and the a ctual position to 0 in
relation to motion position control. The reset signal pulse scale is 10ms or more.
Set the position to 0 at the rising/falling edge of this
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
position table number, start/ stop and origin return to the machine through the PLC.
Also, the user can check output signals such as completion of origin return and
Servo 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.
* Ezi-STEP-PR-MI : maximum
1) To set position table number(0 ~255) to be run by 'PT start' input signal.
2) To set position table number(0~255) to save current position values
'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 LSB(least significant bit ) and A7 is MSB(most
