Signed Master Axis MOVELINK Command
Indirect Writing of Position Data
Program Start Bit Status
Re-execution of WAIT Command

The main axis input sign is ignored
and data is read as an absolute
travel distance. The main axis input sign is evaluated and the
data is read as a signed travel distance.
This function enables the main axis to use the
feedback speed of an axis traveling at low
speed.

Position data can be indirectly
read but cannot be indirectly writ-
ten. Position data can be both read and written indi-
rectly.
Example: Indirect Writing
@PL0000 = 1234;
“1234” will be assigned as the contents of the
address set in PL0000.
This function does not affect previous functional-
ity.

An operation completed bit alone
cannot be used to detect the end
of programs with processing times
that are shorter than the Unit cycle
time. The start bit ON/OFF status in the CPU Unit is
output to the task status bit.
Example for Axis 1:
• n+17 bit 06: start bit (Reserved in previous unit
versions.)
0: Start bit from CPU Unit OFF
1: Start bit from CPU Unit ON
The end of the relevant program can be
detected if this bit is ON and the operation com-
pleted bit is ON.

If the program is stopped while
WAIT command execution is in
effect (i.e., when the deceleration
stop bit is ON) and then re-started
by setting the Start Mode to 1, the
program is started from the next
block after the WAIT command. If the program is stopped while WAIT command
execution is in effect (i.e., when the deceleration
stop bit is ON) and then re-started by setting the
Start Mode to 1, the WAIT command is re-exe-
cuted.
