Troubleshooting
10-2
AC10 Inverter
Fault Description Causes Possible Solution
time
∗ Check whether the communication line is
connected reliably
FL Flycatching Fault Flycatching failure
∗ Track again
∗ Contact manufacturer
PCE PMSM distuning fault
*motor parameters measurement is
wrong.
*load is too heavy.
* Measure motor parameters correctly.
* Decrease the load.
GP Earth fault
Motor cable is broken and
short-circuit to earth
The insulation of motor is broken
and short circuit to earth
Inverter has fault
∗ Change motor cable
∗ Maintain motor
∗ Possible solution refer to OC, OC2 and
ERR4
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?
Too big with load?
Correct wiring
To 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 VVVF
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
