V/F control mode
Acceleration overcurrent
Check if the output loop of the
inverter is grounded or short
circuited with the earth
Whether motor parameter
identification is performed
Whether the acceleration
time is too short
Whether the torque is
manually boosted too much
Whether the voltage is too low
Whether the rotating
motor is directly started
Whether the wires in the
inverter are loose
The model of the
inverter is too small
Remove the
peripheral fault
Perform the motor
parameter identification
Prolong the acceleration
time, increase the
overcurrent stall gain
Reduce the manual
boost of the torque
Sol ve the power
supply problem
Select rotation speed
