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 Pr.79 to 0 to activate fan trip (for models below
22kW capacity).
Displayed when pre-PID is operating with functions set
at AP.34–AP.36. A fault trip occurs when a controlled
variable (PID feedback) is measured below the set value
and the low feedback continues, as it is treated as a load
fault.
Operates when the external brake signal is provided by
the multi-function terminal. Occurs when the inverter
output starting current remains below the set value at
Ad.41. Set either OU.31 or OU.32 to 35 (BR Control).
Displayed when at least one of the two safety input
signals is off.
Protection Functions for Communication Options
Displayed when a frequency or operation command
error is detected during inverter operation by controllers
other than the keypad (e.g., using a terminal block and a
communication mode). Activate by setting Pr.12 to any
value other than 0.
