IMPULSE•G+Mini Advanced Instruction Manual – March 2014
6-7
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.
LL1
(flashing)
Lower Limit 1 Err
Lower Limit 1—SLOW DOWN
Indicator.
Lower Limit 1—SLOW DOWN is
input (switch status is changed).
1. May not require corrective action.
2. Check the position of the Limit Switch.
3. Check the condition of the Limit Switch.
4. Check the conditions of/for input terminal
H01.XX (U01.10).
LL2
(flashing)
Lower Limit 2 Err
Lower Limit 2—STOP Indicator.
Lower
Limit 2—STOP is input (switch status is
changed).
1. May not require corrective action.
2. Check the position of the Limit Switch.
3. Check the condition of the Limit Switch.
4. Check the conditions of/for input terminal
H01.XX (U01.10).
MNT
Maintenance Reqd
Maintenance Required Alert.
Running time
has exceeded C12.05
1. Reset timer by MFI=5A or depress Mode/
Service key three times and enter within 2
seconds.
OC
Over Current
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.
OH
(flashing)
Heatsnk Over temp
Overheat Pre-Alarm.
Heatsink is overheating.
The temperature of the inverter’s heatsink
exceeded the setting in L08.02.
1. The inverter cooling fan has stopped.
2. Reduce the ambient temperature.
OH1
Heatsink MaxTemp
Overheat Fault.
There are two situations that
result in an overheat fault. The first occurs when
the measured heat sink exceeds 105°C. The
second is a result of a fault in the internal
24VDC 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 24VDC fan.
5. Replace the heat sink thermistor(s).
OH2
(flashing)
Overheat 2
Overheat Alarm.
Signal is input by external
terminal. H01.XX=39
OH3
Motor Overheat 1
Motor Overheating 1.
Thermistor analog input
detected motor overheating. See L01.03
1. Check the motor rated current value, E02.01.
2. Increase cycle time or reduce the load.
OH4
Motor Overheat 2
Motor Overheating 2.
Thermistor analog input
detected motor overheating. See L01.04
OL1
Motor Overloaded
Motor Overload Fault.
Inverter output
exceeded the motor overload level.
1. Ensure drive is programmed with proper
motor full load Amps (E02.01).
2. Reduce the load.
OL2
INV Overload
Inverter Overload Fault.
Inverter output
exceeded the inverter overload level.
1. Reduce the load.
2. Extend the acceleration time.
OL8
Klixon
Klixon Circuit Alarm.
Input by MFI data 56 or
57.
1. Check motor for overtemp.
2. Check Klixon circuit.
OPE01
kVA Selection
kVA Setting Fault.
Inverter kVA setting range
is incorrect.
1. Check O02.04 constant for proper kVA.
OPE02
Parameter Range Setting Error.
Parameter
settings are set outside the parameter range.
1. Press enter to view parameter.
2. Change parameter to appropriate setting.
