error
contents
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
W.V.U.
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 inertia is excessive
Over voltage
Check around the noise source
Power supply voltage is too high
Communication reset error
Rework with previous process, if
same message happen again.
Rework with previous process, if
same message happen again.
