CLOSED LOOP PARAMETERS (IDS 612 TO 621)
Select the Closed loop control mode by setting value 3 or 4 for parameter ID600.
Closed loop control mode (see Chapter 600 Motor control mode 234567 (2.6.1)) is used when
enhanced performance near zero speed and better static speed accuracy with higher speeds
are needed. Closed loop control mode is based on "rotor flux oriented current vector
control". With this controlling principle, the phase currents are divided into a torque
producing current portion and a magnetizing current portion. Thus, the squirrel cage
induction machine can be controlled in a fashion of a separately excited DC motor.
