Code
Fault
Description
Possible Cause Solution
100
Overspeed
protection
(protection
against
exceeding the
maximum
speed limit)
Encoder parameter error or
interfered
Check Encoder circuit
Load mutation Check causes of the external load mutation
Overspeed protection
parameter error
Check parameters
101
High-speed
over-current
motor
Low voltage power grid Check the input power
Running load mutation Reduce the load mutation frequency and magnitude
Abnormal motor parameters
setup
Set motor parameters correctly
Encoder parameter error or
interfered
Check Encoder circuit
102
Earthing
protection
Connection error Correct wiring errors according to user manual
Abnormal motor Test earthing insulation before replacing the motor
Over-current leakage of
converter output side against
earthing
Ask professional technical personnel for Ispection
103
Capacitance
aging
Converter capacitor aging
Ask professional technical personnel for Ispection
104
External fault
Failure signal on external
input
Check the external cause of the malfunction
105
Unbalanced
output
Converter output side has
connection exception, miss,
or disconnection
Follow the operational rules and check the wiring of
converter output side, eliminate ignored connection and
disconnection
Unbalanced three-phase
motor
Check motor
106
Parameter error
Parameter error Modify the inverter parameters
107
Current sensor
fault
Driver board hardware
failure
Ask professional technical personnel for Inspection
108
Braking resistor
short circuit
short circuit of external
braking resistor
Check the braking resistor connection
109
Current
instantaneous
value is too
large
When Ia, Ib, Ic is not in
operation, instantaneous
value of three-phase current
is too large and reports alarm
Ask professional technical personnel for Inspection
112
IGBT
short-circuit
Short circuit in periphery Check whether the motor and output wiring is short
circuit, and whether the earthing is short circuit
