Upper limit (FLS)
Lower limit (RLS)
: When the synchronous setting of the PLC CPU is made in the nonsynchronous mode, this must be
provided as an interlock.
When it is made in the synchronous mode, no interlock must be provided in the program because the flag is
turned ON when calculation is run on the PLC CPU.
(6) When stopped with interpolation operation, write "1: Restarts" into "[Cd.6]
Restart command" for the reference axis, and then restart.
(7) If the PLC READY signal is changed from OFF to ON while stopped, restarting
is not possible.
If restart is requested, the warning "Restart not possible" (warning code: 104)
will occur.
(8) When the machine HPR and fast HPR is stopped, the error "HPR restart not
possible" (error code: 209) will occur and the positioning cannot restarts.
(9) If any of reference partner axes executes the positioning operation once after
interpolation operation stop, the warning "Restart not possible" (warning code:
104) will occur, and the positioning cannot restarts.
[3] Control data requiring setting
Set the following data to execute restart.
Setting
value
1 Set "1: Restarts".
[4] Starting conditions
The following conditions must be satisfied when restarting. (Assemble the
required conditions into the sequence program as an interlock.)
(1) Operation state
"[Md.26] Axis operation status" is "1: Stopped".
