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‘.

Description
Over Heat
Latch
Displayed when the tempertature of the inverter
heat sink exceeds the specified value.
Over Current2
Latch
Displayed when the DC circuit in the inverter
