Creating Start Programs For Jog Operation - Mitsubishi Electric MELSEC iQ-FX5 User Manual

Creating start programs for JOG operation

A program must be created to execute a JOG operation. Consider the "required control data setting", "start conditions" and
"start time chart" when creating the program.
The following shows an example when a JOG operation is started for axis 1. ("[Cd.17] JOG speed" is set to "100.00 mm/min"
in the example shown.)
Required control data setting
The control data shown below must be set to execute a JOG operation. The setting is carried out with the program.
n: Axis No. - 1
Setting item Setting
value
[Cd.16] Inching movement 0
amount
[Cd.17] JOG speed 10000
Refer to the followings for the setting details.

Start conditions
The following conditions must be fulfilled when starting. The required conditions must also be assembled in the program, and
the program must be configured so the operation will not start if the conditions are not fulfilled.
Signal name
Interface signal PLC READY signal
READY signal
All axis servo ON
Synchronization flag
Axis stop signal
Start complete signal
BUSY signal
Error detection signal
M code ON signal
External signal Forced stop input signal
Stop signal
Upper limit (FLS)
Lower limit (RLS)
*1 When the CPU module is set to the asynchronous mode in the synchronization setting, the synchronization flag must be inserted in the
program as an interlock condition. When it is set to the synchronous mode, the synchronization flag is turned ON when the CPU module
executes calculation. Therefore, the interlock condition is not required to be inserted in the program.
Setting details
Set "0".
Set a value equal to or below the "[Pr.31] JOG speed limit value".
Signal state
ON CPU module preparation completed
ON Preparation completed
ON All axis servo ON
