The JOG operation is carried out by the following procedure.
Set the JOG data
( JOG. 1 to JOG. 4 )
Create a sequence program that turns ON the
"JOG start signal".
Write the sequence program to the
programmable controller CPU.
Turn ON the JOG start signal of the axis to
be started.
Monitor the JOG operation status.
Turn OFF the JOG operation start signal that is ON.
End of control
Refer to "Section 5.7 Simple reciprocating operation" for details of a JOG operation
starting program.
REMARK
• It is assumed that an external safety circuit and other mechanical elements have
already installed.
• Preset the external I/O signal logic, pulse output mode and pulse rotation direction
with the intelligent function module switches. (For details, refer to "Section 5.6
Switch setting for intelligent function module".)
• Make parameter setting as necessary.
MELSEC-Q
* Using the GX Developer, set the JOG
data and create a sequence program
for executing the JOG operation.
(Set the JOG date in the QD70 buffer
memory using the TO command.)
* Write the sequence program created in STEP
1 to the programmable controller CPU using
GX Developer.
* Turn ON the JOG start signal.
