Display Description Possible reason corrective-measures
Current detection
circuit fault
1. Poor contact of the control board
connector.
2. The auxiliary power supply is
damaged.
3. The Hall device is damaged.
4. The amplifier circuit is abnormal.
1. Check the connector and
reinsert the cable.
2. Search for factory
maintenance.
3. Search for factory
maintenance.
4. Search for factory
maintenance.
Motor to ground
short circuit fault
Short circuit of motor to ground
Check the motor or change the
cable or motor
Motor
auto-tunning
error
1. The capacity of the motor does not
match the capacity of the inverter.
2. Improper setting of rated motor
parameters.
3. The deviation of the self-learned
parameters and the standard parameters
is too large.
4. Auto-tuning timeout. 1. Replace the inverter model.
2. Set rated parameters
according to the motor
nameplate.
3. Make the motor empty and
re-identify.
4. Check the motor wiring and
parameter settings.
EEPROM
reading-writing
error
1. An error occurs in the reading and
writing of control parameters.
2. The EEPROM is damaged. 1.Press STOP/RESE key and
search for factory maintenance.
2.Search for factory maintenance
Accumulated
running time
reaches fault
Cumulative running time to set value
Use the parameter initialization
function to clear the record
information.
Accumulated
power-on time
reaches error
The cumulative power-on time reaches
the set value.
Use the parameter initialization
function to clear the record
information.
Load failure
The running current of the inverter is less
than 11-64.
Check whether the load or 11-64,
11-65 parameters are in
accordance with the actual
working conditions.
PID feedback
disconnection
fault
1. PID feedback disconnected.
2. The PID feedback source disappears.
1. Check the PID feedback signal
line.
2. Check the PID feedback
source.
Wave-by-wave
current limiting
fault
1. Whether the load is too large or the
motor stalls.
2. Inverter power is too small.
1. Reduce the load and check
the motor and mechanical
conditions.
2. Select the inverter with higher
power.
Contact the service provider
Buffer resistor
failure
Whether the input power is abnormal Check the input power
Power-on
initialization
abnormal
1. Whether the input power supply is
abnormal.
2. The power supply or device is
damaged.
1. Check the power supply.
2. Seek service.
