6SEQUENCE PROGRAM USED FOR POSITIONING CONTROL

[2]Starting by inputting external command signal

MELSEC-Q

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.

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).
