Chapter 11 Manual Control
Important
Use the hardware stroke limit function when carrying out JOG operation near the
upper or lower limits. (Refer to Section "13.4.4".)
If the hardware stroke limit function is not used, the workpiece may exceed the
moving range, causing an accident.
Precautions during operation
The following details must be understood before carrying out JOG operation.
(1) For safety, set a small value to "[Cd.17] JOG speed" at first and check the
movement. Then gradually increase the value.
(2) The error "Outside JOG speed range" (error code: 300) will occur and the
operation will not start if the "JOG speed" is outside the setting range at the
JOG start.
(3) The error "JOG speed limit value error" (error code: 956) will occur and the
operation will not start if "[Pr.31] JOG speed limit value" is set to a value larger
than "[Pr.8] Speed limit value".
(4) If "[Cd.17] JOG speed" exceeds the speed set in "[Pr.31] JOG speed limit
value", the workpiece will move at the "[Pr.31] JOG speed limit value" and the
warning "JOG speed limit value" (warning code: 301) will occur in the Simple
Motion module.
(5) The JOG operation can be continued even if an "Axis warning" has occurred.
(6) Set a "0" in "[Cd.16] Inching movement amount". If a value other than "0" is set,
the operation will become an inching operation (Refer to Section 11.3 "Inching
operation").
Operations when stroke limit error occurs
When the operation is stopped by hardware stroke limit error or software stroke
limit error, the JOG operation can execute in an opposite way (direction within
normal limits) after an error reset. (An error will occur again if JOG start signal is
turned ON in a direction to outside the stroke limit.)
