System parameter group 00
PARAMETER DESCRIPTION 96
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 00-22(P.370) ≠ 99999 and RT signal is given, the second motor parameters 05-22(P.332)~
05-37(P.347)，05-38(P.394)~05-39(P.395) are valid, please refer to section 5.2.10 for second function
parameter.
5. RT mentioned here is the function name of “multi-function digital input terminal”. Please refer to
03-00~03-09(P.80~P.84,P.86,P.126~P.128,P.550),03-25~03-30(P.551~P.556),03-33~03-38(P.559~P.564);
Refer refer to section 3.7 for wiring.

Heavy Duty (HD), apply to other duties.
Motor types selection
In order to switch to heavy duty setting ( 00-23(P.186)= 1), be sure to perform the following steps. After these steps
are completed, the duty type will be successfully switched.
1.
Set 00-23(P.186)=0;
2.
Set 00-02=3
(P.998=1)to set all parameters to default;
3.
Set 00-02=2
(P.997=1) to reset inverter.
