Description
Displays a supposed loss in surface tension due to friction at
actual motor speed and by taking into consideration actual
diameter.
This parameter is read-only.
Tension value.
Displays the used weight.
This parameter is read-only.
Used weight.
Displays the actual inertia.
This parameter is read-only.
Actual inertia.
2
Displays angular acceleration of the driven load.
This parameter is read-only.
Angular acceleration.
Displays motor torque reference demand needed to support
current motor speed reference change. The magnitude of
torque demand depends on current acceleration/
deceleration rate and the estimated load inertia.
This parameter is read-only.
Motor torque reference.
Displays the compensation gain currently use, depending on
whether the line speed reference is accelerating,
decelerating or staying unchanged.
This parameter is read-only.
Compensation gain.
Displays motor torque reference used to support motor
speed transition with respect to the compensation gain
factor set in parameters 79.41...79.43.
This parameter is read-only.
Motor torque reference.
