Description
Over Heat
Latch
Displayed when the temperature of the inverter heat
sink exceeds the specified value.
Over
Current2
Latch
Displayed when the DC circuit in the inverter detects a
specified level of excessive, short circuit current.
External Trip Latch
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.
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 Pr.79 to 0 to activate fan trip (for models below
22kW capacity).
Pre-PID Fail Latch
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.
Ext-Brake
Latch
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).
Safety A(B)
Err
Latch
Displayed when at least one of the two safety input
signals is off.
