AC10 Inverter
Fault
Description
Causes
Possible Solution
O.L2
Motor
Overload
 Load too heavy
 Reduce load; *check drive ratio
 Increase motor’s capacity
PCE
PMSM tuning fault
 Load is too heavy
 Motor parameters measurement
is wrong
 Decrease the load
 Measure motor parameters correctly
P.F1.
Input Phase Loss
 Phase loss with input power
 Check if power input is normal
 Check if parameter setting is correct
PF0
Output
Phase Loss
 Motor is broken
 Motor wire is loose
 Inverter is broken
 Check if wire of motor is loose
 Check if motor is broken
Note: No P.F1 protection for single-phase and three-phase under 5.5kW.
Only above 22kW inverters can trip into OC2
Flashing LEDs
Possible Solution
FWD LED Blinking
Inverter is waiting direction command
Table 10-2 Motor Malfunction and Counter Measures
Malfunction
Items to Be Checked
Counter Measures
Motor not Running
Wiring correct?
Setting correct?
Too big with load?
Motor is damaged?
Malfunction protection occurs?
Get connected with power
Check wiring
Checking malfunction
Reduce load
Check against Table 10-1
Wrong Direction of Motor
Running
U, V, W wiring correct?
Parameters setting correct?
Correct wiring
Set the parameters correctly
Motor Turning but
Speed Change not
Possible
Wiring correct for lines with given
frequency?
Correct setting of running mode?
Motor overloaded?
Correct wiring
Correct setting;
Reduce load
Motor Speed Too
High or Too Low
Motor’s rated value correct?
Drive ratio correct?
Inverter parameters are set in-corrected?
Check if inverter output voltage is
abnormal?
Check motor nameplate data
Check the setting of drive ratio
Check parameters setting
Check V/HZ
Characteristic value
Motor Running
Unstable
Too big load?
Too big with load change?
Phase loss?
Motor malfunction.
Reduce load; reduce load change,
increase capacity
Correct wiring
Power Trip
Wiring current is too high?
Check input wring
Selecting matching air switch
Reduce load
Check inverter malfunction
