still correct.
L300P Inverter
Probable Cause(s)
One of three lines of the 3-phase power is missing.
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.
When a thermistor is connected to terminals [TH]
and [CM1] and the inverter has sensed the temper-
ature is too high, the inverter trips and turns OFF
the output.
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.
The 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
