Pr.36
Sudden stop deceleration time
Set the time to reach speed 0 from "
Pr.8
Speed limit value" during the sudden
stop.
The illustration below shows the relationships with other parameters.
When positioning is started,
the acceleration starts following
the "acceleration time".
1) Positioning start
2) Sudden stop cause occurrence
When a "sudden stop cause" occurs,
the deceleration starts following the
"sudden stop deceleration time".
3) Positioning stop
When a "sudden stop cause"
does not occur, the decelera-
tion starts toward the stop
position following the "decel-
eration time".
