6 PLC PROGRAM USED FOR POSITIONING CONTROL
[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 QD75. 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
[X10, X11, X12, X13] 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).
