LCD Display Type Description
multi-function terminal. Set one of the multi-function input
terminals at IN-65-
71 to ‘4 (External Trip)’ to enable external
trip.
BX Level
Displayed when the inverter output is blocked by a signal
provided from the multi-function terminal. Set one of the multi-
function input terminals at IN-65-
71 to ‘5 (BX)’ to enable input
block function.
H/W-Diag Fatal
Displayed when an error is detected in the memory
(EEPRom), analog-digital converter output (ADC Off Set) or
CPU watchdog (Watch Dog-1, Watch Dog-2).
EEP Err: An error in reading/writing parameters due to keypad
or memory (EEPRom) fault.
ADC Off Set: An error in the current sensing circuit
(U/V/W terminal, current sensor, etc.).
NTC Open Latch
Displayed when an error is detected in the temperature sensor
of the Insulated Gate Bipolar Transistor (IGBT).
Fan Trip Latch
Displayed when an error is detected in the cooling fan. Set
PRT-
79 to ‘0’ to activate fan trip (for models below 22 kW
capacity).
InFan Trip Latch It occurs when an abnormality is detected in the cooling fan
inside the inverter with inverter capacity of 110 kW to 500 kW.
Selecting PRT - 79 code to 0 will work.
Thermal Trip Latch
Triggered when the input temperature is higher than the
temperature set by the user.
Lost KeyPad Latch
Triggered when a communication error occurs between the
keypad and the inverter, when the keypad is the command
source, and PRT-11 (Lost KPD Mode) is set to any other value
than ‘0’.
Fuse Open Latch
If an input stage fuse breaks with an inverter of 315 kW or
more, a fault will occur.
