LC Done
Load Check Done
Load Check Done Alarm. This
alarm is displayed after the LC set up
process is done. The alarm will clear
when the Down command is pressed
and complete the LC set up process.
1. None. X
LF
Output Phase Loss
An open phase occurred at the
inverter output.
1. Check for broken wires in output
cable.
2. Check for open winding in the
motor.
3. Check for loose terminals
X
LF2
Output Current
Imbalance
Output Current Imbalance. One or
more of the phases in the output
current are lost.
1. Check for faulty wiring or poor/
loose connections on the output
side of the drive.
2. Correct the wiring.
3. Measure the line-to-line
resistance for each motor phase.
Ensure all values match.
4. Replace the motor.

1. May not require corrective action.
2. Check the Limit Switches
position.
3. Check the Limit Switches
condition.

Maintenance Reqd
Maintenance Required Alert.
Running time has exceeded C12-05
1. Reset timer by H01-0x = 5A or
depress Mode/Service key three
times and enter within 2 seconds.
X
OC
Over Current
Over Current Detected. Output
current exceeds 200% of inverter
rated output current.
1. Check for a phase-to-phase short
in the motor or wiring using a
megger.
2. Extend the acceleration/
deceleration time.
3. Check torque limit setting.
4. Please reference troubleshooting
encoder related faults on page 6-
16.

Heatsnk Over temp
Overheat Pre-Alarm. Heatsink is
overheating. The temperature of the
inverters heatsink exceeded the
setting in L08-02.
1. The inverter cooling fan has
stopped.
2. Reduce the ambient
temperature.

Overheat Fault. There are two
situations that result in an overheat
fault. The first occurs when the
measured heat sink exceeded
105°C. The second is a result of a
fault in the internal 24 VDC cooling
fan.
1. Ensure that the heat sink cooling
fans are functioning.
2. Ensure that the heat sink is free
from dirt and debris.
3. Ensure that the inverter’s
ambient temperature is within
specification.
4. Replace the 24 VDC fan
5. Replace the heat sink
