Fault Detection
Faults are detected for drive protection, and cause the drive to stop while triggering the fault output
terminal MA-MB MC. Remove the cause of the fault and manually clear the fault before attempting
to run the drive again.
Fault Name symbol Description Cause
Memory Data Error Err
EEPROM write error -The power supply was switched
off while parameters were being
saved to the drive.
External Fault EF
External Fault at multi-function -An external device has tripped a
fault function.
-I/O wiring is incorrect.
-Incorrect multi-function contact
input setting
Output Phase Loss LF
Phase loss on the output side of
the drive. -The output cable is disconnected.
-The motor winding is damaged.
-The output terminal is loose.
-An output transistor is damaged.
-The no-load current (E2-03) is set
too high.
-The Motor contactor is not set up
correctly.
Short-circuit SC
Drive current exceeded short-
circuit detection level (maximum
allowable current) -Accel/decel ramp is too short.
-The current level increased due to
a momentary power loss or while
attempting to perform a fault reset.
-The encoder and drive phase
sequence are not the same.
(Interchange A, B of the encoder)
Overcurrent OC
Drive current exceeded
overcurrent detection level -The Load is too heavy.
-Accel/decel ramp is too short.
-The current level increased due to
a momentary power loss or while
attempting to perform a fault reset.
Overload (oL1) oL1
Drive current exceeded motor
overload detection level -The Load is too heavy.
-Accel/decel ramp is too short.
Overload (oL2) oL2
Drive current has been 2 times
greater than the current value sets
in E2-01 parameter -The Load is too heavy.
- The motor current is set
incorrectly
Over Temperature oH
The temperature of the heatsink
exceeded the overheat detection
level -The surrounding temperature is
too high.
-the Load is too heavy.
-The internal cooling fan is
stopped.
Over Voltage ov
Voltage in the DC bus has
exceeded the overvoltage
detection level. -The Deceleration ramp is too
short and regenerative energy is
flowing from the motor into the
drive.
-Fast acceleration ramp causes the
motor to overshoot the speed
reference.
-Drive input power voltage is too
high.
-The braking resistor is not
connected, or wiring is wrong.
-The braking resistance ohm is
higher than standard values.
