overheated
Cause
The input voltage is abnormal
There is large energy feedback
No brake components
Brake energy is not open
is too fast
The voltage of the grid is too low
The power of VFD is too low
The load transients
abnormal
The grounding is short circuited
or the output is phase loss
There is strong
interference
The overvoltage stall protection
is not open
The voltage of the grid is too low
The overvoltage stall protection
is not open
The voltage of the grid is too low
The rated current of the motor is
not correctly set
The motor stall or load transients
is too strong
The acceleration is too fast
Restart the rotating motor
The voltage of the grid is too low.
The load is too heavy.
The motor power is too small.
Phase loss or fluctuation of input
R,S,T
U, V,W phase loss input (or
serious asymmetrical
phase of the load)
Air duct jam or fan damage
Ambient temperature is too high.
Check the input power
Check if the DEC time of the load is
too short, or the motor is started
when it is rotating.
Install a dynamic brake components
Check the setting of relative function
codes
Increase the ACC time
Check the input power
Select the VFD with a larger power
Check if the load is short circuited
or is
(the grounding short circuited or the
wire short circuited) or the rotation is
not smooth
Check the output configuration.
