JOG operation monitor
When using GX Developer to directly monitor the buffer memory, refer to "Section
4.6 List of monitor data".
When using the monitor function of GX Configurator-PT to monitor, refer to "Section
6.6 Monitor/test".
Precautions during operation
Before starting JOG operation, you must know the following information.
(1) Set the JOG data before starting JOG.
(Setting cannot be changed during JOG operation.)
(2) For safety, first set " JOG. 1 JOG speed" to a smaller value and check the
movement. Then gradually increase the value.
(3) If " JOG. 1 JOG speed" is higher than the speed set in " Pr. 5 Speed limit
value", operation is performed at " Pr. 5 Speed limit value" and the "Outside
speed" warning (warning code: 20) occurs.
(4) If " JOG. 1 JOG speed" is lower than " Pr. 6 Bias speed at start", operation
starts at " Pr. 6 Bias speed at start" and the "Outside speed" warning (warning
code: 20) occurs.
If " Pr. 6 Bias speed at start" is "0", starting JOG operation with the setting of
"0" in " JOG. 1 JOG speed" results in the following.
•
0 speed (Md. 7 Status: b2) turns ON.
•
The BUSY signal turns ON. (When the JOG start signal turns OFF, the BUSY
signal turns OFF and "Md. 4 Axis operation status" changes to "Standby".)
In this case, making a speed change with the setting of other than "0" in
" Cd. 7 New speed value" and "1" in " Cd. 6 Speed change request" turns
OFF 0 speed (Md. 7 Status: b2), enabling operation to be continued.
(5) If a warning occurs, JOG operation is continued.
Error during operation
If operation is stopped by the software stroke limit function, J0G operation can be
performed to move the workpiece to within the software stroke limit range after an
axis error reset. (Refer to "Section 11.4" for details.)
