The PwmOffSegment is used to turn off the PWM. Enabling

Float >0 Configures the
maximum velocity
that can be used
during this
segment (absolute
value). The
velocity must be
given in rps.
When limit is
reached, no more
torque is
generated until
velocity is below
limit again.

VLT Integrated Servo Drive ISD
Coefficient representation: This representation is not
available.
FrictionSegment:
The FrictionSegment is used to first measure the friction of
the servo drive system at 2 different velocities. This friction
can either be used for long-term monitoring or the servo
drive can use it for an automatic compensation. The
measurement occurs alternating (over the guide value
cycles) with velocityLow and with velocityHigh.
This segment ends either with the defined velocityLow or
velocityHigh.

M Float Velocity of the axis
during the first part of
the measurement. The
velocity must be given
in rps.
O; no Float Velocity of the axis
default during this segment. The
exists velocity must be given
in rps. To ensure smooth
movements, the
velocities of all segments
that are connected in
the same node should
be the same. If this is
not parameterized
correctly, a jump in
velocity will occur.
O; TRUE/FALSE If TRUE, the measured
default = friction is compensated
FALSE automatically by the
servo drive. If FALSE, the
value can be used for
diagnostics.
