8.2 Fault Display
When a fault occurs during running, the operation panel displays the fault code such as
shown in the following figure.

1. Increase the setting of P3-11 (V/F oscillation suppression gain)
by 10 gradually. The permissible maximum setting here is 100.
1. Decrease the setting of P3-01 (torque boost) by 0.5% gradually.
1. Increase the setting of P0-15 (carrier frequency) by 1.0 kHz
gradually. Note that increase in carrier frequency will result in an
increase in the leakage current of the motor.
1. Set rated motor voltage (P1-02) and rated motor frequency (P1-
04) correctly.
2. Decrease the setting of P3-01 (torque boost) by 0.5% gradually.
1. Ensure that P3-23 (voltage limit selection) is set to 1 (enabled).
Increase the setting of P3-24/P3-25 (frequency gain/voltage gain
for voltage limit) by 10 gradually. The permissible maximum
setting here is 100.
2. Decrease the setting of P3-22 (voltage limit 770v) by 10 V
gradually. The permissible minimum setting here is 700 V.
1. Increase the setting of P3-20 (93-20 factory default set 20) by 10
gradually. The permissible maximum setting here is 100.
2. Decrease the setting of P3-18 (P3-18 factory default is 150%) by
10% gradually.
The permissible minimum setting here is 50%.
Fault reason
Ground fault or short circuit
exists in
the output circuit.
Control mode is FVC or
SVC but motor auto-tuning
is not performed.
Acceleration time is too
short.
The over current stall
prevention
parameters are set
improperly.
Solution
Error settlement

Check whether short-circuit occurs
on the motor, motor cable or
contactor.

Set motor parameters according to
motor nameplate and perform motor
auto-tuning.

Increase acceleration time.

Ensure that current limit is enabled
(P3-19 = 1).

The setting of current limit level (P3-
18) is too large. Adjust it
between 120% and 150%.

The setting of current limit gain (P3-
20) is too small. Adjust it
between 20 and 40.
