Error Status Codes and Error Trip Conditions
The digit to the right of the decimal point in the error code (such as E01.4)
indicates inverter status at the moment the error occurred. Use the Up and
Down arrow keys to scroll through the trip condition parameters.
E21
Inverter thermal trip • Inverter internal temperature is above
the threshold
E23
Gate array error • An internal inverter error has occurred
(CPU / gate array IC)
E24
Phase failure detection • One of three lines of the 3-phase
power is missing
E30
IGBT error • Instantaneous over-current on any
IGBT (output transistor) device
E35
Thermistor • Thermistor input, [TH] and [CM1], is
over the temp. threshold
––––
Under-voltage (brownout)
with output shutoff
• Low input voltage caused the inverter
to turn OFF the motor output and try to
restart. If unsuccessful, a trip occurs.
Automatic restart and phase
loss
• Inverter is restarting, due to an over-
current, over-voltage, under-voltage, or
a phase loss event.
E6x
Expansion card #1 error • 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.
E7x
Expansion card #2 error
