7.12 Fault description and Fault reset:
F01 HW Over Current
The AC drive detects an abnormal increase in current. The maximum allowable hardware current is
300% (9A). When the drive output has exceeded this limit, the “F01” fault code will display on the
parameter unit display.
F02 Over Voltage
The AC drive detects that the DC bus voltage has exceeded its maximum allowable value, 400V.
When the DC bus voltage has exceeded this value, the “F02” fault code will display on the
parameter unit display.
F03 Heatsink OverTmp
The AC drive temperature sensor detects excessive heat. When the Heat Sink temperature has
exceeded 95
o
C, the “F03” fault code will display on the parameter unit display.
F04 Drive Overload
The AC drive detects excessive drive output current. The AC drive can withstand up to 150% of
rated current (4.5A) for 1 minute. When this limit has been exceeded, the “F04” fault code will
display on the parameter unit display.
F07 Motor Overload
The AC drive detects an excessive motor load. When the value of maximum allowable motor load,
which is the setting value of Pr.#99 multiplied by 150% for 1 minute, has been exceeded, the “F07”
fault code will display on the parameter unit display.
F13 Ground Fault
The AC drive output is abnormal. When the output terminal is grounded (short circuit current is 50%
more than the AC drive rated current), the AC drive power module may be damaged. The short circuit
protection is provided for AC drive protection, not user protection.
F14 Under Voltage
The AC drive detects that the DC bus voltage has fallen below its minimum value, 150VAC. When
the input voltage has fallen below this value, the “F14” fault code will display on the
parameter unit
display.
F33 Auto Reset Trials
When the AC drive auto-reset a fault unsuccessfully, the “F33” fault code will display on the
parameter unit display.
F100 EEPROM failure
When the internal memory IC cannot be programmed, the “F100” fault code will display on the
parameter unit display.
NOTE: All the above Faults are re-settable by change the Value of Parameter 110 to 1 and use the
following procedure:
