11.2.1 Outline of JOG operation
JOG 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 Simple Motion module while the signal is ON. The workpiece is then
moved in the designated direction.
The following shows examples of JOG operation.
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.
