No Motor Trip Setting Details
Code Description
PRT-32 No Motor Level,
PRT-33 No Motor Time
If the output current value [based on the rated current (BAS-13)] is lower
than the value set at PRT-32 (No Motor Level), and if this continues for
the time set at PRT-
33 (No Motor Time), a “no motor trip” occurs.
If BAS- 07 (V/F Pattern) is set to “1 (Square)”, set P RT-32 (No Motor Level) to a value lower than the
factory default. Otherwise, “ No Motor T rip” due to a lack of output current will result when the ‘ No
Motor T rip’ operation is set.
10.2.17 Low Voltage Fault Trip 2 During Operation
Group Code LCD Display Parameter Setting range Unit
PRT 82 Low Voltage2 00~11 00 : default Bit
If input power is disconnected during inverter operation and internal DC voltage decreases
lower than a certain voltage, the inverter disconnects the o
utput and displays low voltage “2 ”
on the keypad.
Even if the voltage increases and goes back to the normal state, unlike a low voltage fault, it
remains in a fault state until the user unlocks the fault state.
If PRT- 82 (LV2 Enable) is set to “01,” and if the input power is disconnected during inverter
operation and the internal DC voltage drops to lower than a certain voltage, the inverter stops
output and displays “Low Voltage2.” Unlike the low voltage trip (L ow Voltage), the low voltage 2
(Low Voltage2) trip will not be reset even after the internal DC voltage of the inverter has
recovered to above the trip level. Therefore, you must reset the inverter to reset the trip. The
