Drive control
mode of motor 1
0: V/F control (VVF)
1: Speed sensorless vector control
(SVC)
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.

The start and stop of the inverter are controlled by the RUN key
, STOP key
and multi-function key
on the keyboard. In the case of no fault, press the
multi-function key
to enter the jog running status, and the RUN key
to
enter the running status. If the green LED indicator above the RUN key
