Moment of inertia estimator
(r0108.10)
In the "Open-loop/closed-loop control" area, adds
the "Speed setpoint filter" function. The moment of
inertia estimator can now be activated in the "Pre-
control" subdialog. The dialog is extended by
additional parameters for the moment of inertia
estimator.

Position control (r0108.3) In the "Technology functions" area, activates the
"Position controller" function. Also supplements
the "Basic parameterization" area to include the
"Mechanical system" function.

Precondition
● The drive axis is OFFLINE.
Note
The basic parameterization for the selected drive axis can on
ly be carried out OFFLINE.
Activating a function module
1. To activate a function module, click on the required function module (e.g. technology
controller).
Repeat this step for all additional function modules that you wish to activate.
Note
When th
e "basic positioner" function module is activated, then the "position control"
function module is automatically activated as well.
2. Save the project to back up the settings.

The following control types are available for VECTOR drives:
● U/f control with linear characteristic
● U/f control with linear characteristic and FCC
● U/f control with parabolic characteristic
● U/f control with parameterizable characteristic
● U/f control with linear characteristic and ECO
● U/f control for drive requiring a precise frequency (e.g. textiles)
