Possible reasons
Actions
E-01
Over-current in Acc
process
Too short Acc time
(
including
tuning process
)
Prolong the Acc time
Restart the rotating motor
Start after setting as DC brake, or rotational
speed tracking start
Drive power is too small
Select a higher power drive
V/F curve is not suitable
Adjust V/F curve or torque boost

Check the power supply
Sudden change or abnormal of
load
Check the load or reduce the change of the
load
