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
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
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).
Err
Displayed when at least one of the two safety input signals is
off.
Protection Functions for Communication Options
Command
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
Displayed when the I/O board or external communication
card is not connected to the inverter or there is a bad
connection.
