8.1 What this chapter contains
This chapter describes how to reset faults and view fault history. It also lists all alarm and fault
messages including the possible cause and corrective actions.
Only qualified electricians are allowed to maintain the VFD. Read the
safety instructions in chapter Safety precautions before working
.
8.2 Alarm and fault indications
Fault is indicated by LEDs.
See
Operation Procedure
. When TRIP light is on, an alarm or fault
message on the panel display indicates abnormal state.
Using the information reference in
this chapter, most alarm and fault cause can be identified and corrected. If not, contact INVT
office..
8.3 How to reset
STOP/RST, through digital
input, or by
switching the power light. When the fault has been removed, the motor can be restarted.
8.4 Fault history
Function codes
–
store 6 recent faults. F
–
–
–
show drive operation data when the latest 3 faults occurs.
8.5 Fault instruction and solution
Do as the following after the
1.
Check to ensure there is nothing wrong with the keypad. If not, please contact local INVT office.

. If
parameters to confirm the real state when the current fault occurs by all parameters.
3
. See the following table for detailed solution and check the corresponding abnormal state.
4
. Eliminate the fault and ask for relative help.

Fault code
Fault type
Possible cause
What to do
OUt1
IGBT Ph-U fault
The acceleration is too fast
IGBT module fault
Misacts caused by
interference
The connection of the
driving wires is not good,
Grounding is not properly
Increase acceleration time
Change the power unit
Check the driving wires
Inspect external equipment
and eliminate interference
OUt2
IGBT Ph-V fault
OUt3
IGBT Ph-W fault
OC1
Over-current when
acceleration
The acceleration or
deceleration is too fast
Increase the ACC time
Check the input power
