OLU
Overload protection
Problem
Temperature inside inverter rose abnormally.
Possible Causes
What to Check and Suggested Measures
(1) Temperature around the
inverter exceeded that of
inverter specifications.
Measure the temperature around the inverter.
Î
Lower the temperature (e.g., ventilate the enclosure well).
Î
Reduce the load.
Check the accumulated running time of cooling fan (E52=2).
Refer to Chapter 3, Section 3.8 "Reading Maintenance
Information."
Î
Replace the cooling fan.
(2) The service life of the
cooling fan has expired or
the cooling fan
malfunctioned.
Visually check that the cooling fan rotates normally.
Î
Replace the cooling fan.
Check if there is sufficient clearance around the inverter.
Î
Increase the clearance.
(3) Air vent is blocked.
Check if the heat sink is clogged.
Î
Clean the heat sink.
(4) Load was too heavy.
Measure the output current.
Î
Reduce the load (e.g., reduce the load before overload
occurs using the overload early warning (E34)).
Î
Decrease the carrier frequency (F26).
Î
Enable overload protection control (H70).
(5) The acceleration/
deceleration time was too
short.
Recalculate the required acceleration/deceleration torque and
time from the moment of inertia for the load and the
deceleration time.
Î
Increase the acceleration/deceleration time (F07, F08, E10,
E11 and H54).
(6) The wires to the motor are
too long and caused a
large amount of current to
leak from them.
Measure the leak current.
Î
Connect an output circuit filter (OFL).

E 1
Memory error
Problem
Error occurred in writing the data to the memory in the inverter.
Possible Causes
What to Check and Suggested Measures
(1) The power supply was
turned off when the
inverter was writing data
(especially initializing
data), and the remaining
control circuit voltage was
not high enough to enable
writing of data.
Check if pressing the
key resets the alarm after the
function code data are initialized by setting the data of H03 to
1.
Î
Return the initialized function code data to their previous
settings, then restart the operation.
