Outline of JOG operation

Operation
In JOG operation, the forward run JOG start signal [Cd.181] or reverse run JOG start signal [Cd.182] turns ON, causing
pulses to be output to the servo amplifier from the Motion module while the signal is ON. The workpiece is then moved in the
designated direction.
The following shows examples of JOG operation.
■4-axis module operation example
1.
When the start signal turns ON, acceleration begins in the direction designated by the start signal, and continues for the
acceleration time designated in "[Pr.32] JOG operation acceleration time selection". At this time, the BUSY signal
changes from OFF to ON.
2.
When the workpiece being accelerated reaches the speed set in "[Cd.17] JOG speed", the movement continues at this
speed. The constant speed movement takes place at 2. and 3.
3.
When the start signal is turned OFF, deceleration begins from the speed set in "[Cd.17] JOG speed", and continues for
the deceleration time designated in "[Pr.33] JOG operation deceleration time selection".
4.
The operation stops when the speed becomes "0". At this time, the BUSY signal changes from ON to OFF.

Use the hardware stroke limit function when carrying out JOG operation near the upper or lower limits.
(Page 247 Hardware stroke limit function)
If the hardware stroke limit function is not used, the workpiece may exceed the moving range, causing an
accident.
