☆
These parameters are used to set field weakening control for the synchronous motor.
If P3.18 is set to 0, field weakening control on the synchronous motor is disabled. In this case, the
maximum rotational speed is related to the Inverter bus voltage. If the motor's maximum rotational speed
cannot meet the requirements, enable the field weakening function to increase the speed.
The DLB1 provides two field weakening modes: direct calculation and automatic adjustment.
•
In direct calculation mode, directly calculate the demagnetized current and manually adjust the
demagnetized current by means of P3.19. The smaller the demagnetized current is, the smaller the total
output current is. However, the desired field weakening effect may not be achieved.
•
In automatic adjustment mode, the best demagnetized current is selected automatically. This may
influence the system dynamic performance or cause instability.
The adjustment speed of the field weakening current can be changed by modifying the values of
P3.21 and P3.22. A very quick adjustment may cause instability. Therefore, generally do not modify them
manually.
