PARAMETER DESCRIPTIONS
498 START PULSE MEMORY 3 (2.2.24)
Giving a value for this parameter determines if the present RUN status is copied when the
control place is changed from A to B or vice versa.

In order for this parameter to have effect, parameters ID300 and ID363 must have been set
the value 3.
500 ACCELERATION/DECELARATION RAMP 1 SHAPE 234567 (2.4.1)
501 ACCELERATION/DECELERATION RAMP 2 SHAPE 234567 (2.4.2)
With these parameters, you can make smoother the start and the end of the acceleration and
deceleration ramps. If you set the value to 0.0%, you get a linear ramp shape. The
acceleration and deceleration act immediately to the changes in the reference signal.
When you set the value between 1.0% and 100.0%, you get an S-shaped acceleration or
deceleration ramp. Use this function to reduce mechanical erosion of the parts and current
spikes when the reference changes. You can modify the acceleration time with parameters
ID103/ID104 (ID502/ID503).
