In this display, you transfer the machine data required to generate the acceleration and decelera-
tion ramp. The acceleration up to the maximum frequency (speed) is calculated according to the
following formula:
f= F(I -e-"') + f~~
Where:
frequency at given time
f:
start-stop frequency
t: acceleration time (0. .,3-c)
time constant
F:
