CPF03
CPU Serial Err
Control Board Connection Error.
Connection error between the control board and
the VFD. Can be caused by a connection error, or
the VFD failing to operate properly due to noise
interference.
Connection Error:
1. Turn off the power and check
the connection between the
control board and the VFD.
2. If the problem continues,
replace the control board or
the entire VFD. Contact
Magnetek for instructions on
replacing the control board.
Noise Interference:
1. Check the various options
available to minimize the
effects of noise.
2. Counteract noise in the control
circuit, main circuit, and
ground wiring.
3. Use only recommended
cables or other shielded line.
Ground the shield on the
controller side or the VFD
input power side.
4. Ensure that other equipment
such as switches or relays do
not cause noise. Use surge
suppressors if required.
5. Separate all communication
wiring from VFD power lines.
Install an EMC noise filter to
the VFD power supply input.

CPF06
EEPROM Error
EEPROM Memory Data Error.
An Error in the
data saved to EEPROM. Can be caused by an
error in the EEPROM control circuit, or the power
supply being switched off while parameters are
being saved to the VFD.
Error in the EEPROM Circuit
1. Turn off the power and check
the connection between the
control board and the VFD.
2. If the problem continues,
replace the control board or
the entire VFD. Contact
Magnetek for instructions on
replacing the control board.
Parameter Save Interruption
Reinitialize (A01-05 = 5432).

CPF07
CPF08
Terminal Board Err
Terminal Board Connection Error.
There is a fault connection between the terminal
board and the control board.
1. Turn off the power and
reconnect the terminal board.
2. If the problem continues,
replace the control board or
the entire VFD. Contact
Magnetek for instructions on
replacing the control board.

CPF20
CPF21
CPU Err
Control Circuit Error.
Hardware is damaged.
1. Cycle power to the VFD.
2. If the problem continues,
replace the control board or
the entire VFD. Contact
Magnetek for instructions on
replacing the control board.
