Specimen ;
“CO FBE4 01 0000” ; under normal; 0Hz
“CO FBE4 15 0203” ; under over.C trip
“CO FBE4 15 C203” ; under OC.Drive trip.
“CO FBE4 15 4103” ; under OC.Accel trip
“FBE4” or “FBE2” is 1 byte data, the data is hex data. Example “4103”; “03” has no meaning.
Resolve “41”h bit by bit,
“41”h -> “0100 0001”b
if you found “xxxx xxx1” ; this means Over current detection from CT (CTU or CTW)
if you found “xxxx xx1x” ; this means Over current detection from Rsh
Standard operator is not available on this trouble shooting.
(2) Overload (E 05)
Phenomena: Overload (detected by CT) of the inverter.
This error can be reset 10 seconds after the E05 came out.
Cause: Motor load is heavy.
Remedy: Reduce the load and/or increase thermal level and/or use bigger capacity of
frequency inverter.
Cause: V-Boost value is high.
Remedy: Reduce V-Boost value or increase thermal level and/or use bigger capacity of
frequency inverter.
Cause: Set wrong value for electronic thermal level [b12] and/or electronic thermal
characteristic [b13].
Remedy: Set suitable value.
Cause: Set wrong value for the reactive current of the motor.
Remedy: Set suitable value. Reactive current value which should be input by function mode
is a value measured at 50Hz (60Hz) without load.
Way to Reset: A
(3) Braking Resistor Overload (over voltage) (E 06)
Phenomena: Over Voltage detection after BRD%ED was run out.
Cause: BRD selection is not suitable.
Remedy: Check BRD %ED, BRD resistor ohm, BRD resistor Wattage, BRD resistor wire,
machine inertial, operation cycle.
Way to Reset: A
