Tra Cứu Lỗi Biến Tần Inverter LS Dòng G100

OHt Over Heat Latch Displayed when the temperature of the inverter heat sink exceeds the specified value.
OC2 Over Current2 Latch Displayed when the DC circuit in the inverter detects a specified level of excessive, short circuit current.
E4t 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.65–69 to 4
(External Trip) to enable external trip.
B4 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.65–69 to 5 (BX) to enable input block function.
HWt 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 NTC Open Latch Displayed when an error is detected in the temperature sensor of the Insulated Gate Bipolar Transistor (IGBT).
FAn 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 22 kW capacity)
PID 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
4br 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)
OH Overheat Pre
Alarm		 Latch When the user has set Pr-78 to 2: Free-Run or 3: Dec, pre-overheating warning trip of inverter occurs if the inverter temperature exceeds the temperature set by the user in Pr-77
