Solution to Delta's overload trip fault
1. The main reason for VFD overload
(1) Mechanical overload. The main characteristic of overload is the heating of the motor, which can be detected by reading the operating current on the display.
(2) The three-phase voltage imbalance leads to excessive running current in a certain phase, resulting in overload tripping. It is characterized by uneven heating of the motor ...

When the Delta inverter is powered on, the uptube drive voltage is established
One is hardware, similar to the CPU reset circuit, which gives the downtube a short high-level drive pulse during the initial power-up, and then the voltage drops to 0 to cut off the downtube.
The second is the software, when the CPU is operating normally, it outputs a square wave pulse that only needs to be turned on by the lower three tubes, so that the upper tube ...

Introduction to Constant Power and Constant Torque in Frequency Conversion Speed Regulation - Delta
In general, factory motors are based on the additional speed values obtained at a given power frequency voltage (380 V, 50 Hz). If 380V is not reached under actual operating conditions, e.g. as long as 300V, 50 Hz, the voltage is significantly undervoltaged. Fundamentally, it cannot reach the extra rev value, due to the ...

Consider the timing of increasing the capacity of the inverter - Delta inverter
1. The rated current of the inverter is low
As mentioned above, when the rated current of some inverters is less than the rated current of the motor of the same capacity, the inverter with a larger gear should be considered according to the load condition of the motor.
2. The motor may be overloaded for a short time
Since the electric motor ...
