Fault Tracking
Fault type
1. The connection of the control
board is not good
2. Auxiliary power is bad
3. Some board component is
broken
4. The keypad circuit is
abnormal.
1. The motor capacity does not
comply with the inverter
capability
2. The rated parameter of the
motor does not set correctly.
3. The offset between the
parameters from autotune and
the standard parameters is huge
4. Autotune overtime
1. Error of controlling the write
and read of the parameters
2. Damage to EEPROM
1. PID feedback offline
2. PID feedback source
disappear
1. Braking circuit fault or
damage to the braking unit.
2. The external braking resistor
is not enough
The actual running time of the
inverter is above the internal
setting
setting running time.
The keypad is not in good
connection or offline;
The keypad wire is too long and
Keypad
there is strong interference;
Part of the communication
circuits of the keypad or main
board have fault.
Possible cause What to do
1. Check the connector and
repatch
2. Change the board
3. Change the keypad
1. Change the inverter mode
2. Set the rated parameter
according to the motor name
plate
3. Empty the motor load and
reidentify
4. Check the motor connection
and set the parameter.
5. Check if the upper limit
frequency is above 2/3 of the
rated frequency.
1. Press STOP/RST to reset
2. Change the main control
panel
1. Check the PID feedback
signal
2. Check the PID feedback
source
1. Check the braking unit
2. Select proper braking resistor
Ask for the supplier and adjust
the setting running time.
Check the keypad wire and
ensure it is normal;
Check the environment and
eliminate the interference
source;
Change hardware
