8.2.7 Internal motor control with vector control (MCTRL2)
The function block MCTRL2 controls the motor. Since it is always executed,
it does not need to be entered into the processing table.
Compared with the V/f characteristic control the vector control (C0006 = 1)
has a much higher torque efficiency at the same motor current. The motor
is monitored and controlled via an internal motor model. This serves to
achieve an optimum operating behaviour of the motor at any time.
The vector control can be used for single drives, asynchronous motors and
multi−motor drives of the same type with rigid coupling.
