• For safety, set a small value in Velocity first and check the movement, and then gradually increase the value.
• Use the hardware stroke limit function when carrying out JOG operation near the upper or lower limits. If the hardware
stroke limit function is not used, the workpiece may exceed the moving range and cause an accident.
• When software stroke limit function is valid and, AxisName.Cd.SwStrokeLimit_Override is other than DISABLE or
ONLY_INSIDE, rewrites AxisName.Cd.SwStrokeLimit_Override into ONLY_INSIDE during MCv_Jog execution, and
rewrites it into "" during JOG operation completion.
• When software stroke limit function is valid, and AxisName.Cd.HwStrokeLimit_Override is other than DISABLE or
ONLY_INSIDE, rewrites AxisName.Cd.HwStrokeLimit_Override into ONLY_INSIDE during MCv_Jog execution, and
rewrites it into "" during JOG operation completion.
• Do not change AxisName.Cd.SwStrokeLimit_Override and AxisName.Cd. HwStrokeLimit_Override during MCv_Jog
execution.
• Note that the value of AxisName.Cd.SwStrokeLimit_Override and AxisName.Cd. HwStrokeLimit_Override are retained to
the next instruction during multiple start because the next instruction is analyzed during operation when multiple start is
executed during JOG operation.
• When moving to negative direction against at start after deceleration stop during JOG operation, and when there is a cause
(velocity limit value over, etc.) that an acceleration can not start to the target position, a warning "Out of Speed Range
during Direction Change Warning" (warning code: 0D20H) will occur. (The operation continues with velocity 0.) The moving
starts after changing control to remove the cause.
Ex.
When setting AxisName.Pr.VelocityLimit_Positive = 2000.0, and AxisName.Pr.VelocityLimit_Negative = 1000.0
