1. Parameters to be set for the motor
When the inverter (hereafter referred to as the -VFD) is operating in the "vector control" (F0-03=1) mode, it is highly dependent on accurate motor parameters, which is one of the important differences from the "VF controlled" (F0-03=2) mode. In order for the VFD to have outstanding driving function and operating power, the required motor parameters for the /kloc are (default motor 1 function code):
2. Automatic tuning and identification of motor parameters
The methods of VFD to obtain the internal electrical parameters of the controlled motor include dynamic identification, static identification, and manual input of motor parameters.
The steps for automatic adjustment of motor parameters are as follows:
The following takes the parameter identification method of motor 1 as an example to illustrate, which is the same as that of motor 2.
Step 1: If the motor can be completely separated from the load, in the event of a power failure, the motor is mechanically separated from the load and the motor is allowed to roll freely without load.
Step 2: After powering on, select the VFD command source (F0-04) as the command channel of the operation panel.
Step 3: Accurately enter the nameplate parameters of the motor (such as F4-01 - F4-06). Please press the motor actualparameters to enter the following parameters (according to the motor selection at the time):
Step 4: If it is an asynchronous motor, F4-00 (tuning and selection, for motor 2, it should be H1-00 function code). Please select 2 (Dynamic Full Tuning) and press Enter to confirm. At this moment, the keyboard appears:
Then press the RUN button on the panel, and the VFD will drive the motor to accelerate and decelerate, and run back and forth. The running indicator lights up, indicating that the running duration is about 2 minutes. When the above display information disappears, it will return to the normal parameter display state, indicating that the tuning is complete. After the adjustment, the VFD will automatically calculate the following parameters of the motor:
If the motor cannot be completely separated from the load, please select 1 (static tuning) for F4-00 (H1-00 for motor 2), and then press the RUN button on the panel to start identifying the motor parameters.
3. Set and switch the parameters of multiple sets of motors
It can be specified by the function code H0-00, or the motor parameter set that is useful at the time can be selected by the digital input terminal function 41. However, when the digital input terminal function 41 is useful, it takes precedence, and the H0-00 setting is invalid at the moment.

How to use Delta's inverter operation
(1) When the speed of the motor is controlled by the Delta inverter, the noise and temperature rise of the motor are higher than that of the frequency of the motor. When the motor is running at low speed, because the speed of the motor blades is low, the temperature rise of the motor becomes high.

The benefits of using an inverter – Delta inverter
1. Speed regulation of general motor: By changing the input voltage and frequency of the three-phase asynchronous motor, its speed can be controlled. Generally, when the motor is at low speed, the temperature rise becomes larger due to the decrease in the power of the cooling fan, and the motor load should be reduced according to the frequency.
