Explanation
- Setting the jerk change time
The jerk change time is set in parameter No. 19524 by using the
percentage to the acceleration change time.
The actual jerk change time is represented by the percentage to the
acceleration change time set in parameter No. 1772.
The jerk change time must be within a half of the acceleration change
time, so the value to be set in the parameter ranges 0 to 50 (percent).
If 0 or a value beyond the specifiable range is specified in parameter
No. 19524, look-ahead smooth bell-shaped acceleration/deceleration
before interpolation is not enabled.
- Acceleration/deceleration before interpolation for linear type rapid traverse
When bell-shaped acceleration/deceleration is used in acceleration/
deceleration before interpolation for linear type rapid traverse,
enabling look-ahead smooth bell-shaped acceleration/deceleration
before interpolation applies smooth bell-shaped acceleration/decel-
eration to acceleration/deceleration before interpolation for linear type
rapid traverse.
In this case, the jerk change time is represented by the percentage set
in parameter No. 19524 to the acceleration change time set in
parameter No. 1672.
- Optimum torque acceleration/deceleration
When bell-shaped acceleration/deceleration is used in optimum torque
acceleration/deceleration, enabling look-ahead smooth bell-shaped
acceleration/deceleration before interpolation applies smooth
bell-shaped acceleration/deceleration to optimum torque acceleration/
deceleration.
In this case, the jerk change time is represented by the percentage set
in parameter No. 19524 to the acceleration change time set in
parameter No. 1672.
