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

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 d

oesn’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.
