Code
Fault
Cause
Solution
is incorrect;
The motor stall or load transient is too
strong;
The encoding disk is reverse and
running at low speed for a long time in
closed loop vector control;
The motor power is much larger than
load power
Check the load and adjust the
torque lift;
Adjust the direction of the encoding
disk;
Select the proper motor
OL2
VFD overload
The acceleration is too fast;
Reset the rotating motor;
The voltage of the power supply is too
low;
The load is too heavy;
The encoding disk is reverse and
running at low speed for a long time in
closed loop vector control
Increase the ACC time;
Avoid the restarting after stopping;
Check the voltage of the supply
line;
Select an VFD with bigger power;
Adjust the direction of the encoding
disk

phase
loss
U, V, W phase loss output (or three
phases of the load are seriously
asymmetrical);
The pre-excitation cannot be
completed if the motor is not
connected
Check the output distribution;
Check the motor and cable
OH1
Rectifying
module overheat
Sudden overcurrent of the VFD;
Interphase or grounding short circuit
of three phases;
Air duct jam or fan damage;
Ambient temperature is too high;
The connection of control board is not
good or the plug-ins are loose;
The auxiliary power supply damage
and the drive undervoltage;
The power module bridge is
straight-through;
The control board is abnormal
Refer to solutions to overcurrent;
Re-wiring;
Dredge the air duct or change the
fan;
Low the ambient temperature;
Check and reconnect;
