Err.37 

Offload 

1. The inverter running current 
is less than F8-16 

1. Confirm whether the load is out 
of or F8-16, F8-17 parameter 
settings are consistent with the 
actual running condition 

Err.38 

Rapid

1. Whether the load is too 
large or motor stalling 
2. Small frequency converter

1. Reduce the load and check the 
motor and mechanical conditions 
2. Selection inverter with bigger 
class power

8.2 Common Faults and Solutions 

8.2.1 No Display after Power On 

Inspect whether the input power supply of inverter is the same as the inverter rated voltage or not with 
multi-meter. If the power supply has problem, inspect and solve it. Inspect whether the three-phase 
rectify bridge is in good condition or not. If the rectification bridge is burst out, ask for support. 

Check the CHARGE light on. If the light is off, the fault is mainly in the rectify bridge or the buffer 
resistor. If the light is on, the fault may be lies in the switchover power supply. Please ask for support. 

8.2.2 Power Supply Air Switchover Trips off When Power On 

Inspect whether the input power supply is grounded or short circuit. Please solve the problem. Inspect 
whether the rectify bridge has been burnt or not. If it is damaged, ask for support. 

8.2.3 Motor doesn’t Move after Inverter Run 

Inspect if there is balanced three-phase output among U, V, W. If yes, then motor could be damaged, 
or mechanically locked. Please solve it. If the output is unbalanced or lost, the inverter drive board or 
the output module may be damaged, ask for support.. 

8.2.4 Inverter Displays Normally when Power On, but Switchover at the Input Side Trips when 
Run 

①

 Inspect whether the output side of inverter is short circuit. If yes, ask for support. 

②

 Inspect whether ground fault exists. If yes, solve it. 

③

 If trip happens occasionally and the distance between motor and inverter is too far, it is 

recommended to install output AC reactor. 

④

 If inverter in normal protection, after eliminating error, press STOP/RESET key to reset error, then 

restart inverter. 

⑤

 After eliminating error, inverter power supply shut down, wait until LED display light off, then restart 

inverter. 

⑥

 If above steps cannot get inverter back to normal usage, then take note of the error code displayed, 

and inverter specification, product number, then contact the manufacturer.
