F00.01=0: V/F control (VVF)
It is used for one-to-many, fast and low-precision speed control.
F00.01=1: speed sensorless vector control (SVC)
The open-loop vector control is suitable for general high-performance control. An
inverter drives one motor only of the loads, e.g. machine tools, centrifuges, drawing
machines, and injection molding machines.
1. In order to improve the control performance, self-learning is needed to
obtain the correct motor parameters before vector control.
2. In the vector control mode, the inverter can be used with one motor only,
and the motor capacity should not be greatly different from the inverter capacity;
otherwise, the control performance may decline or the system may not work properly.
