P1093 = ...
Skip frequency 4
P1094 = ...
Skip frequency bandwidth
P1101 = ...
(entered in Hz)
Ramp-up time
P1120 = ...
(enters the accelerating time in s)
Ramp-down time
P1121 = ...
(enters the deceleration time in s)
Rump-up initial rounding time
P1130 = ...
(entered in s)
Ramp-up final rounding time

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.
