8. TROUBLE SHOOTING
8.1 Fault and Trouble Shooting
CHV190 series is the inverter with perfect protection that can give full play to equipment
performance, while be implemented effective protection. However, in the process of using
it also encounter some trouble instructions, and please you analysis according to the
following table to determine the reasons for the timely exclusion occurs. When confronted
with equipment damage so that you can not be solved, please contact with your local
distributor factoring, repairing centers or manufacturers to find a way of solution.
Fault
code
Fault type Reason Solution
OUT1
IGBT Ph-U fault
OUT2
IGBT Ph-V fault
OUT3
IGBT Ph-W fault
1. Acc/Dec time is too
short.
2. IGBT module fault.
3. Malfunction caused
by interference.
4. Grounding is not
properly.
1. Increase Acc/Dec
time.
2. Ask for support.
3. Inspect external
equipment and
eliminate interference.
OC1
Over-current when
acceleration
OC2
Over-current when
deceleration
OC3
Over-current when
constant speed running
1. Short-circuit or
ground fault occurred
at inverter output.
2. Load is too heavy or
Acc/Dec time is too
short.
3. V/F curve is not
suitable.
4. Sudden change of
load.
1. Inspect whether
motor damaged,
insulation worn or
cable damaged.
2. Increase Acc/Dec
time or select bigger
capacity inverter.
3. Check and adjust
V/F curve.
4. Check the load.
OV1
Over-voltage when
acceleration
OV2
Over-voltage when
deceleration
OV3
Over-voltage when
constant speed running
1. Dec time is too short
and regenerative
energy from the motor
is too large.
2. Input voltage is too
high.
1. Increase Dec time
or connect braking
resistor.
2. Decrease input
voltage within
specification.
