Review the power system.
Check that MCCB has been
turned on or no poor contact.
Turned on or Replace MCCB
PF01
Power device failure
during acceleration
The acceleration time is too short. Increase the acceleration time
Boost voltage too high Reduce CD21 contents
Check the motor is locked or the
load is too heavy
Reduce the load factor
Disconnecting the output wiring
U.V.W.
Restart (Run) the inverter check for
the same message
Repair
PF02
Power device failure
during constant
frequency operation
Check for sudden change in load
Eliminate sudden change in
load
Check that the ambient
temperature is too high
Reduce the ambient
temperature
PF03
Power device failure
during deceleration
The load GD
2
is excessive
Set the deceleration time
suitable for load GD
2
Power supply voltage is too high
Reduce th voltage within
specified range
PF04
Power device failure
during stand-by
Check around the noise source.
Power supply voltage is too high.
Remove the cause
Reduce the voltage
EEP1 EEPROM access error
Rework with previous process.
Check for the same message.
Repair
EEP2
EEPROM check-sum
error
LOLO Low voltage
Input voltage is too low.
The load is exessive.
Increase input voltage
Reduce the load
