P1091 =...
Skip frequency 1 (entered in Hz)
Defines skip frequency 1 which avoids
effects of mechanical resonance and
suppresses frequencies within +/- P1101
(skip frequency bandwidth).

Rounding type
0 Continuous smoothing
1 Discontinuous smoothing
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.
P1135 =...
OFF3 ramp-down time
Defines ramp-down time from maximum frequency to standstill for OFF3 command.
