Motor control mode

Induction motor V/F control: user can design proportion of V/F as required and can control multiple motors
simultaneously.

Induction motor close-loop V/F control (VF + PG): user can use optional PG card with encoder for closed-loop
speed control.

Induction motor simple vector control: Output voltage is increased to compensate the frequency change when
motor load is increased.

Induction motor sensorless vector control: Auto-tuning the motor to reach optimal control performance.

Induction motor PG vector control: Increases
output
torque and accuracy of speed control.

Synchronous motor PG vector control: Increases output torque and accuracy of speed control.

Synchronous motor without PG vector control: get the optimal control by the auto-tuning of motor parameters.
Note: 1. The motor capacity must be the same level or one level lower than the inverter capacity.
2. Sensorless vector control: Control performance can be enhanced by auto-tuning. Before setting 00-21
(P.300)= 3 or 4, please set the motor parameters first, then do auto-tuning to increase the precision of the
control.
3. When selecting V/F + PG (set 00-21(P.300) = 1) control mode, please be sure to set the right motor pole
number (05-02(P.303)).
4. When 10-03 (P.151) = 1, the motor performs zero-speed operation under closed-loop vector control; motor
performs DC voltage braking under V/F closed-loop control.
5. When 00-22(P.370) ≠ 99999 and RT signal is given, the second motor parameters
05-22(P.332)~05-38(P.394) are valid, please refer to section 5.2.10 for second function parameter.
6. RT mentioned here is the function name of “multi-function digital input terminal”. Please refer to
03-00~03-05(P.80~P.84、P.86), P.86,for the function selection of multi-function digital input terminal; please
refer to section 3.5 for related wiring.
