In order to avoid torque surges at the transitions (constant velocity phase
←→
accelerating / braking phase), additional rounding-off times P1130 – P1133 can be
programmed. This is especially important for applications (e.g.
transporting/pumping liquids or for cranes) which require an especially "soft", jerk-
free acceleration and braking.
If the OFF1 command is initiated while the drive is accelerating, then rounding-off
can be activated or de-activated using parameter P1134 (refer to Fig. 3-43). These
rounding-off times are defined using parameters P1132 and P1133.

Rounding off after an OFF1 command
In addition to the rounding-off times, the ramp-function generator can be influenced
using external signals. The ramp-function generator provides the following
functionality using BICO parameters P1140, P1141 and P1142.
