11 MANUAL CONTROL
Precautions during operation
(1) For safety, first set " Cd.17 JOG speed" to a smaller value and check the
movement. Then gradually increase the value.
(2) 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 at the
JOG start.
(3) 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".
(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
QD75.
(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.)
