Review the power system.
Check that MCCB has been
turned on or no poor contact.
The acceleration time is too short.
Boost voltage too high
Check the motor is locked or the
load is too heavy
Disconnecting the output wiring
U.V.W.
Restart (Run) the inverter check for
the same message
Check for sudden change in load
Check that the ambient
temperature is too high
The load GD
Power supply voltage is too high
Check around the noise source.
Power supply voltage is too high.
Rework with previous process.
Check for the same message.
Input voltage is too low.
The load is exessive.
Output U.V.W. open
This is normal
Check point

Suggested remedy
Turned on or Replace MCCB
Increase the acceleration time
Reduce CD21 contents
Reduce the load factor
Repair
Eliminate sudden change in
load
Reduce the ambient
temperature
Set the deceleration time
2
suitable for load GD
Reduce th voltage within
specified range
Remove the cause
Reduce the voltage
Repair
Increase input voltage
Reduce the load
Check output U.V.W. circuit
or setting CD93=0
Check communication circuit
or communication code
Setting CD19
