Fault
CPF02
A/D Conversion Error. An A/D conversion error
occurred.
CPF03
PWM Data Error. There is a problem with the
PWM data.
CPF06
EEPROM Data Error. There is an error in the
data saved to EEPROM.
CPF07
Terminal Board Communications Error. A
communication error occurred at the terminal
board.
CPF08
EEPROM Serial Communications Fault.
EEPROM communications are not functioning
properly.
CPF11
RAM Fault.
CPF12
FLASH Memory Fault. Problem with the ROM
(FLASH memory).
CPF13
Watchdog Circuit Exception. Control circuit
damage.
CPF14
Control Circuit Fault. CPU Error (CPU operates
incorrectly due to noise, etc.)
CPF16
Clock Fault. Standard clock error.
CPF17
Timing Fault. A timing error occurred during an
internal process.
CPF18 and
Control Circuit Fault. CPU error (CPU operates
incorrectly due to noise, etc).
CPF19
CPF20 and
RAM fault, FLASH memory error, watchdog
circuit exception.

CPF22
A/D Conversion Fault. A/D conversion error.
CPF23
PWM Feedback Fault. PWM feedback error.
CPF24
VFD Capacity Signal Fault. Entered a capacity
that does not exist (checked when the VFD is
powered up).
CRST
