Err.05
Deceleration
overcurrent
(software)
1. Deceleration time is too
short
2. Load inertia torque is too
big
3. Inverter power is too small
1. Extend deceleration time
2. Add external energy consumption
braking unit
3. Selection inverter with bigger
class power
Err.06
Constant
speed
overcurrent
(software)
1. Load with jump or
abnormal
2. Grid voltage is too low
3. Inverter power is too small
1. Check load or reduce load
jumping
2. Check grid input power
3. Selection inverter with bigger
class power
Err.07
Acceleration
overvoltage
1. The inverter output
circuits exist grounding short
circuit
2. The control model is
vector and has no parameter
identification
3. Low voltage
4. Whether there is a sudden
load in running
5. Small frequency inverter
selection
1. Eliminate outside faults
2. Doing motor parameter
identification
3. Set the voltage to normal range
4. Cancel the sudden load
5. Selection inverter with bigger
class power
Err.08
Deceleration
overvoltage
1. High input voltage
2. In the process of
acceleration, there is an
extant force to drive the
motor running
3. Acceleration time is too
short
4. No installation brake unit
and brake resistor
1. Set the voltage to the normal
range
2. Cancel the external power or
installation brake resistance
3. Increase the acceleration time
4. Installation brake unit and resistor
Err.09
Constant
speed
overvoltage
1. High input voltage
2. In the process of
deceleration, there is an
extant force to drive the
motor running
3. Deceleration time is too
short
4. No installation brake unit
and brake resistor
1. Set the voltage to the normal
range
2. Cancel the external power or
installation brake resistance
3. Increase the acceleration time
4. Installation brake unit and resistor
Err.10
Undervoltage
1. Instantaneous power
failure
2. The voltage of the inverter
input is not in the scope of
the specification
requirements
3. Bus voltage is not normal
4. Rectifier bridge and buffer
resistance is not normal
5. Driven board abnomal
6. Control panel abnormal
1. Reset fault
2. Adjust the voltage to normal range
3. Seeking technical support
4. Seeking technical support
5. Seek technical support
6. Seeking technical support
