acceleration
type
Acceleration without breakpoints (normal) and
with breakpoints (multistep acceleration) can be
selected normal

acceleration
The duration is the time necessary for running from the previous frequency to the prescribed one.
The starting point of the characteristics is 0 Hz. If the last frequency (f4) is lower than fmax, then
between f4 and fmax the acceleration occurs with the normal slope. The acceleration consists of
linear sections. If the prescribed frequency is lower than the previous one, it will be disregarded by
the program!

Effect of the “S” curve
(the same at acceleration and deceleration)
Submenu Explanation, further submenus Values Default setting Unit
2-4
S curve
It means the impleme
ntation of “soft” transitions in the breakpoints of the acceleration, expressed
by
means of time. This is the transition time from one slope to the other. The “S” curve is effective
in the start and end points at normal acceleration, and in all breakpoints at acceleration with
breakpoints! Without programmed “S” curve, the form of the transitions is “angled”
2-4-2 transition time
This is the time elapsing at changing-over from
one steepness to the other.
N: No change-over time, the nature of the change-
over is “angled”.
N
0,01 - 10,00 N s
The acceleration and deceleration times become longer by the transition time. The transition from one slope value to
another occurs without breaks, continuously. The steepness of the rise and fall does not change in the straight sections!
