Ground short circuit
18
Er.GF
1. Motor burnout or insulation aging
2, the cable is damaged and contact,
short circuit
3. The distributed capacitance of the
terminal and motor cable is larger
motor cable
4, bad hardware
1. Confirm the insulation
resistance of the motor. If it is
turned on, replace the motor.
2. Check the power cable of the
motor to eliminate the fault
point.
3, reduce the carrier frequency,
install the output reactor
4, seeking technical support
module temperature
detection fault
20
Er.tCK
1, temperature detection line broken
2, drive board is faulty
3. Main control board is faulty
4, the environmental temperature is too
low
1. Check the thermistor wiring
2. Ask for technical support
3. Ask for technical support
4, manual intervention to drive
the temperature rise
Current
detection fault
21
Er.CUr
1: The HALL device is faulty.
2: The drive board is faulty.
3: The control board is faulty
1: Replace the faulty HALL
device.
2: Replace the faulty drive
board.
3: Ask for technical support.
Encoder offline
22
Er.PGL
1. motor locked
2. encoder pulse setting wrong
3. encoder offline
1 check motor and mechanical
condition
2 set correct parameter for
encoder
3 check encoder connecting line
Motor
over-speed
25
Er. oS
1: The encoder parameters are
setincorrectly.
2: The motor auto-tuning is
notperformed.
3: The over-speed detectionparameters
are set incorrectly
1: Set the encoder
parametersproperly.
2: Perform the motor
auto-tuning.
3: Set the over-speed detection
parameter correctly based on
the actual situation.
Too large
speed
deviation
26
Er.DEV
1: The encoder parameters are
setincorrectly.
2: The motor auto-tuning is
notperformed.
3: The detection parameters of toolarge
speed deviation are setincorrectly.
1: Set the encoder parameters
properly.
2: Perform the motor
auto-tuning.
3: Set the detection parameters
correctly based on the
actualsituation.
Motor
auto-tuning
fault 1
27
Er.tU1
1: The motor parameters are not set
according to the nameplate.
2: The motor auto-tuning times out.
1: Set the motor
parametersaccording to the
nameplateproperly.
2: Check the cable connecting
between the Frequency inverter
and themotor.
