FEATURE SELECT
[S-Curve Rounding] — P.111
Rate of change (positive or negative) of
acceleration and deceleration to smooth the
Speed Loop Ramp output. For example, if equal
to 20, then 40 % of the acceleration and
deceleration time will be spent smoothing and
the remainder will be a linear ramp.
0% = linear ramp, no rounding
50% = smoothing for the entire ramp
In regard to [Trim Mode Type], [S-Curve
Rounding] will interfere with the [Accel
Time] and the [Decel Time] so that the draw
will not be constant. Therefore, it is
recommended that [S-Curve Rounding] be
set to 0% if [Trim Mode Type] is set to
Proportional. Incremental trim is not affected
by this limitation.
