NOTE: If an EEPROM error (E08) occurs, be sure to confirm the parameter data values are
still correct.
E24
Phase failure detection
One of three lines of the 3-phase power is missing.
E30
IGBT error
When an instantaneous over-current condition
occurs on any IGBT (output transistor) device, the
inverter alarm trips. then it turns the outputs OFF
in order to protect the circuitry.
E35
Thermistor
When a thermistor is connected to terminals
[THM] and [CM1] and the inverter has sensed the
temperature is too high, the inverter trips and turns
OFF the output.
––––
Under-voltage (brownout)
with output shutoff
Due to low input voltage, the inverter turns its
output OFF and tries to restart. If it fails to restart,
then the alarm trips to record the under-voltage
error event.

An error has occurred in an expansion card or at
its connecting terminals. Please refer to the
