Probable Cause(s)
• Inverter internal temperature is above
the threshold
• An internal inverter error has occurred
(CPU / gate array IC)
• One of three lines of the 3-phase
power is missing
• Instantaneous over-current on any
IGBT (output transistor) device
• Thermistor input, [TH] and [CM1], is
over the temp. threshold
• Low input voltage caused the inverter
to turn OFF the motor output and try to
restart. If unsuccessful, a trip occurs.
• Inverter is restarting, due to an over-
current, over-voltage, under-voltage, or
a phase loss event.
• An error has occurred in an
expansion card or at its connecting
terminals. Please refer to the manual for
the expansion card for additional details.
