4 POSITIONING DEDICATED SIGNALS
4.1.7 Common devices
POINT
(1) Internal relays for positioning control are not latched even within the latch range.
(2) The range devices allocated as internal relays for positioning control cannot be
used by the user even if their applications have not been set.
(1) PLC ready flag (M2000) .........................................Command signal
(a) This signal informs the Motion CPU that the PLC CPU is normal.
1) The positioning control, home position return or JOG operation using the
servo program which performs the Motion SFC program when the
M2000 is ON.
2) The above 1) control is not performed even if the M2000 is turned on
during the test mode [TEST mode ON flag (SM501) : ON] using
MT Developer2.
(b) The setting data such as the fixed parameters, servo parameters and limit
switch output data can be changed using MT Developer2 when the M2000
is OFF only.
The above data using MT Developer2 cannot be written when the M2000 is
ON.
(c) The following processing are performed when the M2000 turns OFF to ON.
1) Processing details
• Clear the M-code storage area of all axes.
• Turn the PCPU READY complete flag (SM500) on.
(Motion SFC program can be executed.)
• Start to execute the Motion SFC program of the automatic starting from
the first.
2) If there is a starting axis, an error occurs, and the processing in above
(c) 1) is not executed.
3) The processing in above (c) 1) is not executed during the test mode.
It is executed when the test mode is cancelled and M2000 is ON.
