detects a specified level of excessive, short circuit
current.
Displayed when an external fault signal is provided
by the multi-function terminal. Set one of the multi-
function input terminals at IN-65-71 to ‗4 (External
Trip)‘ to enable external trip.
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.
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.).
Displayed when an error is detected in the
temperature sensor of the Insulated Gate Bipolar
Transistor (IGBT).
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).
Triggered when the input temperature is higher
than the temperature set by the user.
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‘.
General Fault Trips
Triggered when the damper open signal or run
command signal is longer than the value set at AP2-45
(Damper Check T) during a fan operation.
