[2] Starting by inputting external command signal
When starting positioning control by inputting the external command signal, the
start command can be directly input into the Simple Motion module. This allows
the variation time equivalent to one scan time of the PLC CPU to be eliminated.
This is an effective procedure when operation is to be started as quickly as
possible with the start command or when the starting variation time is to be
suppressed. To start positioning control by inputting the external command signal,
set the "data required to be set" and then turn ON the external command signal.
Restrictions
When starting by inputting the external command signal, the start complete signal
will not turn ON.
Data required to be set
To execute positioning start with the external command signal, set parameter
([Pr.42]) beforehand, and validate the "external command signal" with the "external
command signal validity setting program (program No.5).
Setting
value
0 Set to "0: External positioning start".
