Indication
Name
Possible fault reason
Corrective action
OC3/UC3
Over current during
constant speed
1: The insulation of motor
and motor wire is not good
2: Load fluctuation
3:Fluctuation of input
voltage and the voltage is
low
4: Inverter capacity is
inappropriately set
5: Whether there is a large
power motor starting up
and leads the input voltage
goes down
6: Whether there is a
disturbing resource to
disturb inverter
1: Check the insulation of
motor and motor wire 2:
Check load situation and
mechanic
al lubrication
3; Check input voltage
4: Enlarge the capacity of
inverter
5: Increase capacity of
transformer
6: Solve disturbing resource
OUO
Over voltage
during stop
1: The deceleration time is
short
2: Inverter capacity
incorrectly set
3: Disturbing
1:
Check the power supply
voltage
2: Sent for repairing
OU1
Over voltage
during acceleration
1: Abnormal power supply
2: Peripheral circuitry is
incorrectly set (switch
control on or off, etc.)
3: Inverter fault
1: Check the power supply
voltage
2: Do not u
se power supply
switch to control the inverter
on or off
3: Sent for repairing
OU2
Over voltage
during deceleration
1: Power supply voltage
abnormal
2: Energy feedback load
3: Braking resistor
incorrectly set
1; Check the power supply
voltage
2; Install b
raking unit and
resistance
3: Affirm resistance setting
again
OU3
Over voltage
during constant
speed
1: Decelerate time is too
short
2: Power supply voltage
abnormal
3: Over load
4: Braking resistor
incorrectly set
5: Braking parameter is
incorrectly set
1: Increase deceleration
time
2: Check the power supply
voltage
3: Check braking unit and
resistance
4: Set Braking resistor over
again
5: Correctly set parameter,
e.g. braking tube voltage,
etc.
