13. Program Support Functions
(3) Program error (P35) occurs when an illegal system number has been issued.
(4) The synchronizing command is normally issued in a single block. However, if a movement
command or M, S or T command is issued in the same block, whether to synchronize after the
movement command or M, S or T command or to execute the movement command or M, S or
T command after synchronization will depend on the parameter (#1093 Wmvfin).
#1093 Wmvfin
(5) If there is no movement command in the same block as the synchronizing command, when the
next block movement starts, synchronization may not be secured between the part systems.
To synchronize the part systems when movement starts after synchronization, issue the
movement command in the same block as the synchronizing command.
(6) Synchronizing is done only while the part system to be synchronized is operating automatically.
If this is not possible, the synchronizing command will be ignored and operation will advance to
the next block.
(7) The L command is the synchronizing identification number. The same numbers are
synchronized but when they are omitted, the numbers are handled as L0.
(8) The synchronizing command designates the number of the other part system number to be
synchronized, and can also be issued along with its own part system number.
(Example) Part system "i" command: !i!n!mLl;
(9) When the part system No. is omitted (when only "!" is issued), part system 1 will be handled as
"!2" and part system 2 as "!1". The command using only "!" cannot be used for synchronizing
with part system 3 and following.
If the command using only "!" is used for part system 3 or following, the program error (P33)
will occur.
(10) "SYN" will appear in the operation status section during synchronization. The synchronizing
signal will be output to the PLC I/F. ($1: X63C, $2: X6BC, $3: X73C, $4: X7BC, $5: X83C, $6:
X8BC, $7: X93C)
13.13 Synchronizing operation between part systems
0: Synchronize before movement command execution.
1: Synchronize after executing movement command.
