11.2.2 JOG operation execution procedure 

The JOG operation is carried out by the following procedure.   

 

STEP 1

Preparation

Refer to
CHAPTER 5 and
Section 11.2.3.

End of control

Set the parameters 

STEP 2

Refer to Section

11.2.4. 

Set the " Cd. 17 JOG speed".

STEP 3

Turn ON the JOG start signal. 

STEP 4

One of the following two methods can be used. 

<Method 1>

Monitor using GX Configurator-QP.

<Method 2>

<Method 1>

<Method 2> 

STEP 5

Write the sequence program to the CPU module.

Turn ON the JOG start signal of the axis to be started. 

Monitoring of the
JOG operation

STEP 6

Set a "0" in " Cd. 16 Inching movement
amount".

Create a sequence program in which the "JOG start

signal" is turned ON by a JOG operation start command. 

 

One of the following two methods can be used. 

Directly set (write) the parameters in the QD75 using GX 
Configurator-QP.

Set (write) the parameters from the CPU module to the QD75 
using the sequence program (TO instruction).

Using GX Developer, set the control data and create a 
sequence program for executing the JOG operation. 
(Set the control data in the QD75 buffer memory using the TO 
 instruction.)

Write the sequence program created in STEP 1 and 
STEP 2 to the CPU module using GX Developer.

 Reverse run JOG start signal

Monitor using GX Developer.

Stop the JOG operation when the JOG start signal is turned 
OFF using the sequence program in STEP 2.
