Do you know how to set the motor characteristics of the inverter-controlled mechanical equipment? Next, Sanke Inverter will introduce this aspect for you through the following content.
1. Parameters to be set for the motor
When the inverter (hereafter referred to as -VFD) is operating in "vector control" (F0-03=1) mode, it is highly dependent on accurate motor parameters, which is one of the important differences from "VF control" (F0-03=2) mode. In order for the VFD to have good drivability and operational efficiency, /kloc
The required motor parameters are (default motor 1 function code):
2. Automatic tuning and identification of motor parameters
VFD's methods for obtaining the internal electrical parameters of the controlled motor include dynamic recognition, static identification, manual input of motor parameters, etc.
The steps for automatic adjustment of motor parameters are as follows:
The following takes the parameter recognition method of motor 1 as an example, which is the same as that of motor 2.
Step: If the motor can be completely separated from the load, in the case of a power failure, the motor is mechanically separated from the load and the motor is allowed to rotate freely without load.
Step 2: After powering on, first 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 Motor ActualParameters to enter the following parameters (selected according to the current motor):
Step 4: If it is an asynchronous motor, F4-00 (for tuning selection, for motor 2, it should be the H1-00 function code). Please select 2 (Dynamic Full Tuning) and press Enter to confirm. At this point, the keyboard displays:
Then press the RUN button on the panel, and the VFD will drive the motor to accelerate and decelerate, running 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 is completed, the VFD will automatically calculate the following parameters of the motor:
If the motor cannot be completely separated from the load, select 1 (static tuning) for F4-00 (H1-00 for motor 2) and press the RUN button on the panel to start the identification of 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 currently valid motor parameter set can be selected by the digital input terminal function 41. However, when the digital input terminal function 41 is valid, it takes precedence, and the H0-00 setting is invalid at this time.
