Chapter 6 Troubleshooting
171
Fault
Display
Name of Protection
Possible Cause to Fault
Countermeasure
SP0
Output phase loss or
imbalance
Output R,S & T phase loss
or imbalance
Check the output
connection line
Check the motor and
cable insulation
CCF1
Control circuit fault 0
Transmission between the
frequency and the keypad
cannot be established
within 5s after power is
supplied (when power is
just supplied)
Re-pull out and re-insert
the keypad
Check the connection
line
Replace the keypad
Replace the control panel
CCF2
Control circuit fault 1
The frequency and the
keypad communicate once
after power is supplied, but
the transmission fault
afterwards last for at least
2s (in operation)
CCF3
EEPROM fault
EEPROM fault with the
control panel of frequency
inverter
Replace the control panel
CCF4
AD conversion fault
AD conversion fault with
the control panel of
frequency inverter
Replace the control panel
CCF5
RAM fault
RAM fault with the control
panel of frequency inverter
Replace the control panel
CCF6
CPU disturbance
Serious disturbance
MCU reading & writing
error with the control panel
The communication line is
connected reversely or the
dialing switch dials
incorrectly
Reset via the
button
STOP
RESET
Add the power filter at
the power side
additionally
Seek the technical
support
PCE
Parameter copying error
②
Error with the parameter
copying between the
keypad and EEPROM of
the control panel
EEPROM of the control
panel is damaged
Repeat the copying
operation
Replace the control panel
Seek the technical
support
HE
Current detection fault
Fault with the frequency
inverter current detection
circuit
The Hall elements are
damaged
Replace the frequency
inverter
Seek the technical
support
Notes:
①
The small/medium-power inverters (Type 3022G/3030P and the below) have not the Uu2 fault
(undervoltage with the control circuit) and the Uu3 fault (poor charging circuit).
②
Only the selectively-configured LCD keypads have the function of parameter copying, while the standard
LED keypads have not the function.
