JOG Operation

Overview of the JOG operation

Use the hardware stroke limit function when performing the JOG operation at a position close to the upper or
lower limit. (Page 239 Hardware stroke limit function)
If the hardware stroke limit function is not used, the workpiece may be moved beyond the movement range
resulting in an accident.
Operation
JOG operation moves a workpiece in the specified direction by turning on the [Cd.181] Forward run JOG start signal or the
[Cd.182] Reverse run JOG start signal is turned on to output pulses from positioning module to the drive unit. The following
figure illustrates an example of JOG operation.

1.
When a start signal is turned on, acceleration starts and continues in the direction specified by the start signal for the
acceleration time specified with [Pr.32] JOG operation acceleration time selection. BUSY signal turns on at this time.
2.
The accelerating workpiece continues moving at the speed set with [Cd.17] JOG speed once it is reached. (The
workpiece moves at a constant speed between operation steps 2 and 3.)
3.
When the start signal is turned off, deceleration starts and continues in the direction specified by the "[Cd.17] JOG
speed" for the deceleration time specified with [Pr.33] JOG operation deceleration time selection.
4.
Operation stops when the speed reaches 0. BUSY signal turns off at this time.
