10.2.3.4 B45 action autotune SLVC
WARNING!
Risk of injury due to high speeds!
The action accelerates the motor up to twice its nominal speed.
Make certain the components fastened to the motor are sufficiently secured
against centrifugal forces (by feather keys, coupling elements, etc).
Make sure that any mechanical systems (gear units, etc.) that are attached
can reach these speeds.
NOTICE
Unsuitable optimization results!
The results are falsified if the action is performed with a loaded motor.
If possible, only perform the action when the motor is not connected to a
mechanical system (gear units, etc.).
If it is not possible to disconnect the mechanical system, make sure that the
load torque is not more than 10 % of the nominal torque.
The action determines the following parameters for control mode 3: ASM -
Sensorless vector control:
• B46 Feedback ASM Observer
• B47 Proportional part of speed approximation
• B48 Integral part of speed approximation
When the action is complete you can read the new parameter values in B46 ...
B48.
You can start the action in B45[0], observe the progress in B45[1] and obtain
the result in B45[2].
To start action B45 autotune SLVC, set B45[0] = 1:active.

WARNING!
Personal injury and material damage due to falling loads.
Starting the action will cause the motor brake to be vented. Since the motor is
not adequately powered by the action, it is unable to hold any loads (for
example in a lifting function).
Use the action only for motor that are not under any load.
Progress of the action as a %.

Information
To start the action, change from Low level to High level of the
enable. If there is a brake present it will be released automatically.
After the end of the action the enable must be aborted.
