Possible Causes What to Check and Suggested Measures
(2) A high intensity noise was
given to the inverter while
data (especially initializing
data) was being written.
Check if appropriate noise control measures have been
implemented (e.g., correct grounding and routing of control
and main circuit wires). Alternatively, perform the same check
as described in (1) above.
Î
Improve noise control. Alternatively, return the initialized
function code data to their previous settings, then restart the
operation.
(3) The CPU did not operate
normally.
Initialize the function code data by setting H03 to 1, then reset
the alarm by pressing the
key and check that the alarm
goes on.
Î
This problem was caused by a printed circuit board (PCB)
(including the CPU) malfunction, so it is necessary to
replace the PCB. Contact IMO.
[ 13 ] E 2 Remote keypad communications error
Problem A communications error occurred between the remote keypad and the inverter.
Possible Causes What to Check and Suggested Measures
(1) Break in the
communications cable or
poor contact.
Check continuity of the cable, contacts and connections.
Î
Replace the cable.
(2) A high intensity noise was
given to the inverter.
Check if appropriate noise control measures have been
implemented (e.g., correct grounding and routing of control
and main circuit wires).
Î
Improve noise control.
(3) The remote keypad
malfunctioned.
Check that alarm
E 2
does not occur if you connect another
remote keypad to the inverter.
Î
Replace the remote keypad.
(4) The RS485
communications card
malfunctioned.
Check that alarm
E 2
does not occur even if you connect
another remote keypad to the inverter.
Î
Replace the card.

E 3
CPU error
Problem A CPU error (e.g. erratic CPU operation) occurred.
Causes What to Check and Suggested Measures
(1) A high intensity noise was
given to the inverter.
Check if appropriate noise control measures have been
implemented (e.g. correct grounding and routing of control
and main circuit wires).
Î
Improve noise control.
(2) The printed control circuit
board in the inverter
malfunctioned.
