In order to achieve a satisfactory controller response, as a minimum, you must match the
subfunctions having a gray background as shown in the diagram above with your particular
application.
● Motor and current model: In the basic commissioning, correctly set the motor data from
the rating plate corresponding to the connection type (Y/Δ), and carry out a motor data
identification routine at standstill.
● Speed limits and torque limits: In the basic commissioning, set the maximum speed
(p1082) and current limit (p0640) to match your particular application. When completing
the basic commissioning, the inverter calculates the torque and power limits
corresponding to the current limit. The actual torque limits are obtained from the
converted current and power limits and the set torque limits.
● Speed controller: Start the rotating measurement of the motor data identification. You
must manually optimize the controller if the rotating measurement is not possible.
Default settings after selecting the application class Dynamic Drive Control
Selecting application class Dynamic Drive Control adapts the structure of the vector control
and reduces the setting options:
Hold or set the integral component of the
speed controller
