Advanced commissioning
6.5 Motor control
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 basic commissioning, set the motor data from the rating
plate corresponding to the connection type (Y/Δ), and carry out a motor data identification
at standstill.
● Speed limits and torque limits: In the basic commissioning, set the maximum speed
(p1082) and current limit (P0640) for your particular application. When exiting 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 torque limits that have been set.
● Speed controller: Use 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
