LCD Display
Type
Description
Over Current1
Latch
Displayed when inverter output current exceeds 180% of the
rated current.
Over Voltage
Latch
Displayed when internal DC circuit voltage exceeds the
specified value.
Low Voltage
Level
Displayed when internal DC circuit voltage is less than the
specified value.
Low Voltage2
Latch
Displayed when internal DC circuit voltage is less than the
specified value during inverter operation.
Ground Trip
Latch
Displayed when a ground fault trip occurs on the output side of
the inverter and causes the current to exceed the specified
value. The specified value varies depending on inverter
capacity.
E-Thermal
Latch
Displayed based on inverse time-limit thermal characteristics to
prevent motor overheating. Operates when PRT-40 is set to a
value other than ‘0’.
Out Phase Open Latch
Displayed when a 3-phase inverter output has one or more
phases in an open circuit condition. Operates when bit 1 of
PRT-
05 is set to ‘1’.
In Phase Open
Latch
Displayed when a 3-phase inverter input has one or more
phases in an open circuit condition. Operates only when bit 2
of PRT-
05 is set to ‘1’.
Inverter OLT
Latch
Displayed when the inverter has been protected from overload
and resultant overheating, based on inverse time-limit thermal
characteristics. Allowable overload rates for the inverter are
120% for 1 min and 140% for 5 sec.
No Motor Trip
Latch
Displayed when the motor is not connected during inverter
operation. Operates when PRT-
31 is set to ‘1’.

Signals
LCD Display
Type
Description
Over Heat
Latch
Displayed when the temperature of the inverter heat sink
exceeds the specified value.
Over Current2
Latch
Displayed when the DC circuit in the inverter detects a
specified level of excessive, short circuit current.
External Trip
Latch
Displayed when an external fault signal is provided by the
