20 Main Normal Start 3
• This program starts automatically at the time of RUN of Q173CPU(N), and
it is always executed.
• Watch data is taken out, and clock data read request (M9028) is turned on.
• The initials condition of the internal relay (M100) for the stop is turned on.
• The subroutine starts "No.170 : Stop".
• The subroutine starts "No.150 : Programming operation".
• When an forced stop is released, all axes servo are turned on.
• Turns off actual output (PY) at the time of the forced stop.
170 Stop Normal Not start 3
(1) When a stop input signal (PX5) from the input unit is off, the treatment of
the following (2) is executed, and 1 axis and 2 axes executed the following
(3) during servo on in the case of the one except for it.
(2) 1 axis and 2 axes stop command are turned off, and an internal relay
(M100) for the stop is turned off.
(3) 1 axis and 2 axes stop command are turned on, and an internal relay
(M100) for the stop is turned on.

Program
operation
Normal Not start 3
(1) The following motion control is executed.
1) This program stands by until PX4 is turned on.
2) 1 axis and 2 axes are located in (0,0) in the linear interpolation control
(absolute 2 axes positioning).
3) Positioning completion signal on of 1 axis and 2 axes are confirmed.
4) In-position on of 1 axis and 2 axes are confirmed.
5) 1 axis and 2 axes are located in (1000000, 2000000) in the linear
control (absolute 2 axes positioning).
6) Positioning completion signal on of 1 axis and 2 axes are confirmed.
7) This program stands by until PX4 is turned off.
(2) When a positioning completion signal of the above (1) 3) and 6) is off, it
waits to turn off, and (When a positioning was suspended on the way.)
execute the motion control step (1) 2) or 5) again.
(3) Until an internal relay (M100) for the stop turns it on, it does not move to
the next step of the above (1) 1) and 7).
