Ramp function generator (RFG)
Skip frequency 1
(entered in Hz)
Defines skip frequency 1, which avoids
effects of mechanical resonance and
suppresses frequencies within +/- p1101
(skip frequency bandwidth).

The rounding times are recommended as
abrupt responses can be avoided therefore
reducing stress and damage to the mechanical
system.
The ramp-up and ramp-down times are
extended by the component of the rounding
ramps.
OFF3 ramp-down time
Defines ramp-down time from maximum frequency to standstill for OFF3 command.
