Description
Under Load
Latch
Displayed when the motor underload trip is activated and the
actual load level is less than the set level. Operates when PRT-27 is
set to a value other than ‘0’.
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’.
