Encoder
Fault
Err20
1: The encoder model does not
match.
2: The cable connection of the
encoder is incorrect.
3: The encoder is damaged.
4: The PG card is faulty
1: Set the encoder type correctly
based on the actual situation.
2: Eliminate external faults.
3: Replace the damaged encoder.
4: Replace the faulty PG card.
EEPROM
Read and
Write Failure
Err21
Damaged EEPROM Chip
Replace the main control board.
Inverter
Hardware
Malfunctions
Err22
1: Overvoltage;
2: Overcurrent.
1: Deal it as overvoltage error;
2: Deal it as overcurrent error.
Ground
Fault Errors
Err23
Ground fault of the motor
Change electric cables or motors.
User-Define
d Fault 1
Err27
The user-defined fault 1 signal is
input via Terminal X.
Reset the operation
User-Define
d Fault 2
Err28
The user-defined fault 2 signal is
input via Terminal X.
Reset the operation
Reach the set
total
Power-On
Time
Err29
Accumulated power-on time
(F8.13) reaches the set value
(F4.16).
Clear the records using the initiation
of parameters.
Offload
Errors
Err30
Operation current of inverter is
smaller than F9.64.
Confirm the removal of load or if
parameters setting of F9.64 and
F9.65 matches real situation.
PID
Feedback
Lost
During
Operating
Err31
The PID feedback is lower than
the setting of FA.26.
Check the PID feedback signal or
set FA.26 to a proper value.
CBC Errors
Err40
1: Excessive load or motor
stalling;
2: The model of inverter is too
small.
1: Reduce load and inspect the
motor and mechanical conditions;
2: Use the inverter that has a higher
power level.
Large Speed
Deviation
Err42
1: The encoder parameters are set
incorrectly.
2: The motor auto-tuning is not
activated.
3: F9-69 and F9-70 are set
incorrectly.
1:Set the encoder parameters
properly.
2: Perform the motor auto-tuning.
3: Set F9.69 and F9.70 correctly
based on the actual situation.
Motor
over-speed
Err43
1: The encoder parameters are set
incorrectly.
2: The motor auto-tuning is not
activated.
3: F9.67 and F9.68 are set
incorrectly
1:Set the encoder parameters
properly.
2: Perform the motor auto tuning.
3: Set F9.67 and F9.68 correctly
based on the actual situation.
