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 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 in the quick commissioning adapts the
structure of the vector control, and reduces the setting options:
Closed-loop torque control without
higher-level speed controller
Droop
K - and T
P
Hold or set the integral component of
the speed controller
Acceleration model for precontrol
Motor data identification at standstill
or with rotating measurement
Converter with the CU240B-2 and CU240E-2 Control Units
