(2) Precautions during operation
• For safety, first set "[Cd.17] JOG speed" to a smaller value and check the movement. Then gradually
increase the value.
• The axis 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 or 0 at the JOG start.
• The axis 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".
• 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 LD75.
• The JOG operation can be continued even if an "Axis warning" has occurred.
• Set a "0" in "[Cd.16] Inching movement amount". If a value other than "0" is set, the operation will become an
inching operation. (

(3) 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.)
