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