Settings that are required
In order to achieve a satisfactory control response, as a minimum you must set the partial
functions – shown with gray background in the diagram above – to match your particular
application:
● Motor and current model: In the quick commissioning, correctly set the motor data on the
rating plate corresponding to the connection type (Y/Δ), and carry out the motor data
identification routine at standstill.
● Speed limits and torque limits: In the quick commissioning, set the maximum speed (p1082)
and current limit (p0640) to match your particular application. When exiting quick
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
Acceleration model for precontrol
Motor data identification at standstill or with ro‐
tating measurement
Converter with the CU230P-2 Control Units
